Here's what it's doing. The regular "diesel knock" that is given with the sound of every diesel motor, completely goes away when I get off the gas. And when I come to a stop at idle, the "knock" is all over the place, and shakes the entire truck. Also, the motor is stock (no tune, etc.) and is blowing black smoke out the exhaust at idle. And when I give it a little gas, it smokes the sh!t out of everything. What's going on with this thing?? I drove it from Texas to NC Friday, and it ran fine for the most part, but did throw an over boost code half way back. The code went away by itself, and the service engine light is not on right now. Whats going on??

Most likely injectors.
Covered under the 200,000/7year warranty.

Well Zeus, I'm not sure..... could be a fuel stop you made on the way back. Here's what I mean.

Last week while traveling in AR I stop at a BP (British Petrolium) to refuel (my first and last one to use). I had 1/2 a tank on my 2003 Dmax so I didn't need a lot of fuel. I just wanted to get a head start on the next morning's departure.

The sign priced diesel at $3.35 a gallon. I pulled in, grabed the "GREEN" handle and filled up... paid and left. Drove about 12 miles to the house and stopped. Got in it about 30 mins. later and drove about 1 mile... stopped.... came back to the house.... left again. Drove about 15 miles... stopped, got out, got back in.... wouldn't start! Turned over just fine but wouldn't fire. I pumped the primer on the fuel filter housing... and it started... gave white smoke out the back and shortly died.

This went on for serveral tries, then I started going over everything I had done in the last 45 miles......? Filled up!

I checked my receipt.... unleaded! From a "GREEN" handle at BP. It seem BP uses a "green" handle for both premium unleaded AND diesel.

I drained the entire tank and made sure I got diesel.... Fired right up... runs great... no side effect that I can tell... gets 22 miles to the gallon @ 65 and 20 @ 70.

Check those receipts!

Fuel injectors, fuel rail pressure regulator, there isn't really enough info there to diagnose the problem. Does the engine lope (rum-rum-rum-) or just idle generally rough? Take it to a dealer, or find someone with a scan-tool able to read balance rates, and that will tell you if its the injectors. check the engine oil, is it over-full, smell like diesel?

I filled up at a BP about 15 miles ago. But the diesel pumps are competely separate from the gas pumps.

The engine lope at idle is all over the place and it shakes the sh!t out of the entire truck.

Zeus, thanks man... I learned that after the fact. Out hear in Texas (most of the time) it's all at the same pump.... black handle, black handle, black handle, "green handle".

I'll be paying attention better in the furture. I've been told you came really mess one up with the wrong fuel.

The engine lope at idle is all over the place and it shakes the sh!t out of the entire truck.

is there a rythm to it? or is it more like a random miss-fire?

is there a rythm to it? or is it more like a random miss-fire?
It's completely random.

alright. Check your oil, make sure its not over-full and/or smell like diesel fuel. Then I'd get the balance rates checked, preferably at a dealer that you trust the service department, as its most likely going to need new injectors. You should be within the time-frame for the special policy injector coverage, and as long as you have less than 200K miles they should be under waranty. You'll know for sure if it is indeed the injectors after the balance rates are checked.

I filled up earlier today at a BP and not only is it a entire differant pump island, it is a yellow handle.

So they Chevy dealership just called me and told me that it is a bad fuel injector, but it is NOT under any warantee!! WTF! They told me the fuel injectors were already replaced on the truck and when they were replaced they only came with a 12 month 12k mile warantee. They also told me that this ONE fuel injector was going to cost me over $1200 to get fixed!!! WTF!!!!!!!!!!!!!!!!!!!!!!!

Did they tell you what was wrong with it? If it is because of high return rates or any other issue that is listed in the special policy, it wouldnt matter how many times it went bad.

do a search for the service bulletein. print it off and take it with you. if that dealer gives you a really hard time, i'd take it to another one. call the gm service line while you're at the dealership and tell them what's going on.

If for some reason the dealership or any dealership won't help you. Someone is selling a set of LB7 injectors in the marketplace.

http://www.dieselplace.com/forum/showthread.php?t=201437

They also told me that this ONE fuel injector was going to cost me over $1200 to get fixed!!! WTF!!!!!!!!!!!!!!!!!!!!!!!

Sorry to hear about your situation.....it's nothing new on this board. The extended special policy only covers very specific failures. Bascially injectors that exhibit high return rates due to cracked cases or ball seat erosion are the failures the special policy covers.

Like others have suggested, ask why it's not being covered under the special policy. I use to have a copy of the special policy but I threw it away with the truck!!! At any rate, I don't remember any verbage regarding to the number of replacments allowed. It simply stated the type of failure and as long as it occured before 200k/7yr they should be replaced.

For now I'll add you to the list of those not covered by the special policy....Sparky?????

That's complete BS. It should be covered. When I had mine replaced, they told me I could have the replaced as many times needed up to 200K/7 yrs. I am sorry that you are having so many issues. That is a great motor and a great truck.

How hard is it to change a fuel injector? The dealership wants $1200 parts and labor to change 1 injector. I found a remanufactured injector for $200. Is this something I can do myself?

if nothing else, I believe that I saw a full set of 8 injectors (or rebuild kits) in the market place for $1200. If no other solution is realized, thats way better than 1200 for one.

How hard is it to change a fuel injector? The dealership wants $1200 parts and labor to change 1 injector. I found a remanufactured injector for $200. Is this something I can do myself?

The hardest part is removing all the hardware to get to the valve cover. One side is easier to get to then the other.

Once you get to the valve covers it's more just time then anything else. Three of my injectors I was able to pull out by hand. One required some prying.

Of course I took mine apart with the engine out of the truck (long story). I would plan at least a full day if not a weekend. Depends on how much wrenching experience you have.

Just my opinion, but if you do the job yourself you might as well replace all 4 injectors. It's a bit of work, even for the Tech at the dealer, and given the LB7 injector problem you might as well replace all 4 at once. It would suck to do all that work and loose another a couple of months later.

So I went back to the dealer today to talk to the service manager. All I have to say is.....ASSHOLE!!! He's trying to pull out everything he can to get me to pay for this. I don't understand. It's not like his dealership would pay for it, GM would. I asked to get the diagnostic in writing. He didn't want to give it to me. His reason for the problem not being associated with the special policy that would cover it....it didn't throw a code. WTF!!! It doesn't have to. The policy says it MAY throw a code. Not 'must' throw a code. And the one part that would immediately link the problem with the special policy is a fuel return flow rate test..........WHICH THEY DIDN'T DO BECAUSE IT DIDN'T THROW A CODE!!! They're suposedly doing the flow rate test now at my request, but I have a feeling the results will be BS anyway.

That sucks. Tell him to eat sh*t and go to another dealership. The are not all bad. I didn't throw a code either when mine went out.

Run, don't walk to a different dealership .... as fast as your black smoke belching truck can get you there!

The stealership gets paid a lot less on a warranty job than on a customer job. AND 5 will get you 10 that he was planning on having GM foot the bill too. If he wasn't an out and out thief, he would have been glad to provide you with the documentation.

And you're wrong, he's not an A**hole - he's no where near up to that level!

His reason for the problem not being associated with the special policy that would cover it....it didn't throw a code.


Never heard of any Injector failures throwing codes...mine didn't.

I think you need to start digging for the Cust. Serv. 1-800 #

Yeah like everyone else said, go to another dealer. My truck needed injectors in March, I went through the same thing you are going through...just go to another dealer.

Please name the dealer and the location!

Sorry to hear your bad luck Zeus.

Either go to another dealer or apologize to the service manager for leaving a footprint on his forehead as you step on it to go over it and talk to a regional GM rep.

The dealership is Reid Lallier Chevrolet in Fayetteville, North Carolina.

I'm already talking with Chevrolet about this.

Please follow up and let us know how Chevy handles the situation.

Well, I just got off the phone with the service manager. It seems our little "pep talk" this morning has given him a change of heart. lol Apparantly, the fuel flow test I requested this morning never got done (BS) and they are going to change the one injector at no cost to me. I'm not bitching, but I'm pretty sure this guy didn't just have a change of heart without some evidence. I'm thinking the pressure test got done....and was infact bad. Oh well, either way, the injector is now being changed. http://www.horsepowerjunkies.com/forums/images/smilies/smile.gif

Excellent, however I would be curious what the return test showed. The dealer did not have a change of heart, do not be fooled. He is not taking a hit on this job to "satisfy" you. If you catch my drift. I would get your free injector and take it to another shop.

Not to be ignorant or anything...But the other injectors are most likely not too far behind. When you go to pick the truck up, I'd demand a return rate test, and take that evidence to another dealer. If it goes in again for the same symptoms, make them do all eight injectors.

So I finally got the truck back after the the dealer hoarding it for 10 days. They changed one injector. The only thing they told me about it....the #6 injector had an internal problem. However....they did charge me $100 to get the truck back. Are any of you having to pay a $100 GMPP Deductible for getting your injectors replaced?

I'm surprised they only changed one injector. All that work they might as well change all the injectors on that side. Cheap bastards. Better find yourself a good dealer cause there will be more troublesome injectors in your future.

Happily, my truck is still on original injectors, but the special service policy has no deductable.

He is ripping you off.

(You should have kicked him to the curb and gone to a different dealer....)

Go back and ask him where it shows the deductable on the special warranty for injectors. If it says nothing demand your money back. If he will not give it to you call GM and report it. Like everyone else said, FIND ANOTHER DEALER

I believe the deductable is $100 when mileage is over 100k.

I would have, but then they would have nailed me with the diagnostics fee, which I'm sure they would have run up on me. I argued with the service lady about the deductable for about 30 minutes. I wanted to see it in writing that there was actually a deductable, but they couldn't show it to me. I tried to call my contact that I have been talking to at GM, but she wasn't available. I'll keep trying to get ahold of her and see what she says.

the TSB state is the reutrn flow rate are bad ALL INJECTOR get replaced not just one or 2

i droped my truck off with a crankcase full of oil and diesel back in OCT.

This bulletin is being revised to include additional model years and revised warranty information. Please discard Corporate Bulletin Number 04-06-04-007E (Section 06 -- Engine/Propulsion System).


--------------------------------------------------------------------------------

Condition
Some customers may comment on the Service Engine Soon light becoming illuminated. Upon investigation, the technician will find DTCs P0087, P0093 or P1093. Additional customer comments may include a lack of power, a fuel smell on the oil dipstick, fuel in the engine oil, fuel coming out of the crankcase breather, the engine cranks but does not run, or a hard start condition. This condition will not cause an engine misfire. Do not apply this bulletin to any diagnostic other than what is identified in the chart below.

Cause
The fuel injectors have internal conditions that may cause them to return an excessive quantity of fuel to the tank, as well as leak fuel into the crankcase. Due to the return flow and/or leakage, the fuel injection pump may not be able to build up adequate fuel rail pressure.

Correction
Important: Before the technician begins diagnostics and repair, be sure to follow the guidelines in Corporate Service Bulletin Number 03-06-04-036 to avoid fuel system contamination.

Follow current diagnostics for the condition the vehicle is experiencing, then reference the table below. If the diagnostics lead to Fuel System Diagnosis - High Pressure Side, follow the diagnostic until the Fuel Injector Return Flow is measured at each cylinder bank return connection (bank to bank).

Condition
Start with this SI Diagnostic in the Diagnostic Information and Procedures sub-section of the Engine Controls Section

Delayed Start
Hard Start

Lack of Power
Lack of Power, Sluggishness or Sponginess

Engine Cranks but Does Not Run

DTC P0087

DTC P0093
DTC P0093

DTC P1093

Important: If the SES light is illuminated, follow diagnostics for the DTC as indicated with the Tech 2.

Important: When installing the new fuel injectors, lubricate the inside of the fuel injector sleeve with clean engine oil prior to installing the injector. Do not lubricate the injector or O-ring seal prior to installation.

If fuel return flow on either the right or left cylinder bank is above the initial fuel injector bank return flow value, then replace all eight (8) fuel injectors using the Fuel Injector Replacement procedure in the Engine Controls section of the appropriate Service Manual.

Record all diagnostic data as outlined on a copy of the attached diagnostic worksheet. The diagnostic worksheet and a copy of the repair order is to be returned with the removed injectors.

After replacing injectors, perform the following steps:

Replace the fuel filter element.
Install all disconnected and removed components. Refer to the applicable procedures.
Start and idle the engine. You may have to prime the fuel system before the engine will start.
Connect a scan tool.
Command the fuel pressure control to 160 MPa with a scan tool.
• If the fuel pressure is more than 145 MPa, the system is OK.

• If the fuel pressure is unable to increase to more than 145 MPa. Refer to System Diagnosis -- High Side Pressure in the appropriate Service Manual.

• Be sure to record fuel pressure readings on the diagnostic worksheet.

Also, the original add time to replace all injectors was overstated, Finally, the number of diagnostic steps have been adjusted because individual injectors are not being diagnosed. The labor time guide will be revised in the near future.


Important: All replaced injectors must be returned to the WPC. IMPORTANT: WAIT TO RECEIVE THE WPC PART RETURN REQUEST PRIOR TO RETURNING THE INJECTORS. Please follow Corporate Bulletin Number 99-00-89-019C that applies to the WPC return procedures. All eight (8) injectors of a single engine must arrive at the WPC boxed or bagged together. A copy of the part request, repair order with technician comments and the completed diagnostic worksheet should be included with the injectors. The tags found in the replacement injector box must be completed and attached to each injector. The WPC will be verifying sets of injectors for high flow rates.

about half way down the TSB;)

I can't believe those cheap EFFERS only replaced one!!:eek::rippedhan That is such BS.

Print off the TSB that was posted above and take it to that service manager and demand all injectors be replaced, the $100 be refunded and a full all out detail of your truck for the inconvenience. Then be sure to call your contact and inform her of the service you recieved, they get bad bolo's from GM for negative remarks from customers. That = less money made at the end of the year.

The thing is, my contact at GM isn't really helping me out much. She's just documenting everything. This whole experience has just put a bad taste in my mouth about this truck as well as General Motors for not helping me with a crooked dealer. I've always been a loyal GM costumer since my first vehicle, but things might be changing soon. And that sucks for me to actually say that.

I read that part word for word to my contact at GM and she all but ignored it. Apparently the dealer stated that "it seems like the truck's computer has been modified." So they are trying to void the policy, and consider changing my one injector a favor. The truck has stock exhaust, stock intake, etc., but they're trying to say it's been programmed. I'm tired of this already and I've owned the truck for 2 weeks.

Magnuson-Moss Warranty Act
US Code - Title 15, Chapter 50, Sections 2301-2312

Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302(C)) . For best results, consider working with performance-oriented dealerships with a proven history of working with customers. If your vehicle manufacturer fails to honor emission/warranty claims, contact EPA at (202) 260-2080 or www.epa.gov (http://www.epa.gov/). If federal warranty protection is denied, contact the FTC at (202) 326-3128 or www.ftc.gov (http://www.ftc.gov/). For additional information, check out the following links:

Federal Warranty Laws
1.The Magnuson-Moss Warranty Act (15 U.S.C. 2302(C))
This federal law regulates warranties for the protection of consumers. The essence of the law concerning aftermarket auto parts is that a vehicle manufacturer may not condition a written or implied warranty on the consumers using parts or services which are identified by brand, trade, or corporate name (such as the vehicle maker's brand) unless the parts or service are provided free of charge. The law means that the use of an aftermarket part alone is not cause for denying the warranty. However, the law's protection does not extend to aftermarket parts in situations where such parts actually caused the damage being claimed under the warranty. Further, consumers are advised to be aware of any specific terms or conditions stated in the warranty which may result in its being voided. The law states in relevant part:
“No warrantor of a consumer product may condition his written or implied warranty of such product on the consumers using, in connection with such product, any article or service (other than article or service provided without charge under the terms of the warranty) which is identified by brand, trade or corporate name...” (15 U.S.C. 2302(C)).

Call a lawyer. They can be expensive but these people you are talking to will open their ears a lot further when contacted by your attorney!

I just checked my oil..........about 5 quarts too much, and I'm guessing it's not oil. There is a faint scent of diesel on the dip stick. 4 days after I got it back from the dealer changing one injector.

I had checked my oil the day it got towed to the dealer. It was fine, right where it should have been, and no diesel scent. This is absolutely rediculous, and GM is not giving me ANY help.

Man I hope you get this figured out, I have had an experience or two like this and I feel for you. Good luck and I hope you get those a-holes straightened out and get your truck fixed.

If that's diesel fuel in your oil, it'll show if you drip some on a clean paper towel if it has fuel in it, it will sort of "wick" up from the oil stain with a lighter color which is the fuel. Please keep us informed.

Where can I take some of the oil to get an analysis done? How much do I need to take?

man take that thing to Raleigh already they will replace it my buddy has blown two motors and they replaced them both under warranty no questions asked and one got replaced after another dealer refused to do it and the rep had looked at it. it's still going right now and he is in the process of getting his 06 motor rebuilt right now.

dude why in the fudge are you still going to that dealer? go to a different one and proceed to tell every1 about that shady dealer!!

I won't go back to that dealer. GM was actually arguing with me, telling me to take it back to that dealer again.....I told them no way in hell.

Man there's like 3 GM dealers over here in Jacksonville, one in Richlands, and I'm sure a few more close to you - take it somewhere with a reputable service department.

I guess you could count yourself lucky. Stationed up here in AK we don't have many dealerships to pick from, its better than it was when I was stationed up here 10 years ago though, then we only had one.

Glad mine is still on its origional injectors, we will see what this winter does to them.

does this special policy cover LLY motors too???

I don't think so. At least not yet. lol This policy is just for '01-'04 LB7's from what I understand.

Please don't tell us the LLY has injector problems!:mad:

I just started having a injector #3 misfire code. same symptoms. didn't turn on the SES light and onstar couldn't find it. My mechanic buddy did with his computer though. Truck has 125K on it. I really don't want to shell out 3 grand to replace them but I can't really wait for GM to add my truck to the list.

I just printed a bunch of stuff off this topic to show my dealer (McEleney Autoplex in Iowa City). They are always real good to me. If mine has the same symptoms as the special policy describes I think they will help me out.

I would probably put money on the fact that once more and more LLY's get to higher milage we will start to hear about more and more injector problems.

LLYs don't have the same injector setup as LB7s do. LLYs have a injector wiring harness issue but thats about the extent of injector problems...

premis, how many miles do you have on your truck? i see its only three years old, so it is still under the 5 year part of the engine warrentee. if it is still under the factory warrentee, it should be fixed for free, or a $100 deductable type thing. and no, the LLY's are not covered under the special bullitin. only the LB7's.
and when you go in, take out the edge. less wuestions to be asked of you, and no possable denial of warentee work do to the edge.

No deductible

Also in the policy statement:

Warranty Information
Important: This labor operation listed below is covered by emissions and is not subject to the $100.00 deductible. Dealer’s will need to use the following information when submitting claims on vehicles still covered under that warranty:
I checked my invoice and I was wrong they didn't charge the 100.00, they did charge 1 hour for changing the NSBU switch and the air filter and there is no note that they changed the fuel filter. the policy states to change it before checking return rates after repairs are made to the injectors.
