Engine knock started two days ago. didn't drive it yesterday. Started it today and knock was worse with white smoke. Shut it down. Started it this evening with efi live hooked up. It started with knock and smoke, then it shut down. nothing on efi but I am a novice with its capabilities. Stereo and clock were acting up and time reset. ECM? I am going to start looking in service manual but any insight would be greatly appreciated. This doesn't look good.:eek:

try draining your fuel filter to make sure you dont have water in it -- its been a while since my brother inlaw had water in his dodge but his simptoms were similar to yours. check your oil to see if you have fuel in it -- if so you better get it in . your right -- it isnt looking good

did it just stop sudden. hows your oil.

it stop suddenly. i was stepping on the accelerator to raise the rpms and it stopped dead. i get a click when i turn the key but that is it. i have disconnected the batteries 10 minutes ago or so. i am going to reconnect and see what happens. i will check the fuel filter and it does have oil. no puddle under it either.

is there fuel in the oil? you might want to return your tune to stock, my truck would not start and when i remove the chip it started right up.

i did return to stock tune after it died. i didn't want to forget, the stealer would blame me for sure. thanks

keep us informed-- i hope it works out!

no go yet. batteries are at 50%. charging now. Ice/sleet starting. I'm south of Chicago. About two weeks ago I replace a directional pulley and serpentine belt. I don't think this has anything to do with it, but I don't want to leave anything out. Thanks

i lived there for a while - only place i have ever been where a scarf has froozen to my face. try priming the filter after every few turns of the key. my gauge was off and i ran mine dry it took at least a half a dozen times.

Still wont start. When I turn the key you can hear the starter hit but no turn over. sounds like that concrete breaker (just not as loud, but with that hollow thud). If that makes any sense. Please tech guys a little help please.

update:P0340 code camshaft position sensor circuit bank 1 sensor "A". didn't find any bad fuses either.

Ouch!!

Well, at least your pretty close to Eric. That's who I'd go to with it.

Mongoosefun, where are you located? Maybe I could help ya out, but it's sure sounding like big motor problem. Could be a million things. I'm in Manhattan, if you're close, I'll swing by.

Not filter prime, it won't crank. The "hollow thud" is the bendix hitting the flywheel and stopping, from the sounds of it.

I'd pull the Glow plugs out and see if it will turn over. If the cylinders are full of coolant it will lock up. If you continue to try and turn it over you might bend a rod. I would def pull the plugs and see if it's coolant. If it's not then it doesn't sound good. Sorry!

Sounds like it is locked up. Probably a "hydraulic" issue. Maybe either fuel from a stuck injector or coolant from a head gasket. Maybe a warranty issue?

I would talk to a few people before you choose your dealership if it is possible warranty work. A trip on a trailer to the "right" dealer would be cheaper than a tow to the wrong one who will give you tons of aggravation.

Does it try to turn over at all or does the starter just go click, click when you hit the key?

I live on the state line IL/IN outside of Beecher. It does not turn over at all. just the thud.

How much screwing around with the EFI have you done? If the cam sensor is bad more than likely the timing is way off and it will not light.

Hence the white smoke unburnt diesel and knocking.WHEN it ran

Depending on what you have done with the EFI and the timing being way off you may have at this time caused contact with piston and valvetrain and are now in a hydro loc situation with broken parts in the combustion chamber NOT allowing the crank to make full revolution. If YOU muffed with the timing table (sounds like it) which has caused the code and the contact well...

In other words your screwed.

Well, if you decide you need a hand, let me know. Beecher's about 15-20 away from me, through the back roads of course! :)

Here's a good test for you. Have someone else sit in the truck. You go keep your eyes on the pulleys. Have them hit start and watch to see if there's ANY movement at all. If there is, chances are you're hydrolocked (pulling the gloplugs and cranking will evacuate anything in cylinder)...if it doesn't move at all, you've got a real problem. WATCH carefully, the movement may be hard to see.

I used a basic efi program from Kennedy. I didn't do anything crazy, because i was afraid of blowing the trans. I am one of those guys who goes into a rubber room with a steal ball and end up coming out with two pieces. If you make I can break it. Thanks for the help so far. tomrex I'll give it a try. be back soon.

OK there was some movement and I heard an electrical current noise. the kind you hear when you are hooking the battery back up. It was around the passenger side battery. The plot thickens.

Ok, dont get your hopes up, but now its time to take out the glo plugs and crank it. watch to see what comes out the holes. if it turns over freely with them out, you have bad head gaskets and coolant is leaking into the cylinders. if it doesnt crank...internal atomic bomb went off and it's time for major motor work. :)

keep in mind, also, if colant comes pouring out the holes, the truck still needs work...but its a lot better than bottom end work like a busted rod or crank.

Are you sure you don't have a bad battery! I have had many problems with bad batteries over the years & with the electronics now really wacky things happen. Actually I had an alternator that went to over charging, clear up to 18 on the volt meter. The D max just shut down. Had a heck of a time getting it to restart after that.

Throw some PB Blaster or some kind of penatrant on those glow plugs before you pull them. Don't wanna break one and add to your dilema.

Well the batteries are new and the glow plugs came out (didn't break any). When my wife turned it on for me I heard that electric current sound. Could an electrical short cause this type of scenario?

Did the motor turn over??? or was it that goofy electrical noise being made? a short could definatly give you running issues if the pump doesn't know what to do. i know this may sound crazy, but double check both batteries and that the cables are attached to the correct posts. after that, start chasing where that electrical noise is coming from.

Also check the big wire that goes to the starter...if that one's shorted to something, there will be a big drain and a ot of noise!

We may have found one of the problems. First I have been charging the batteries when they are disconnected because of the draw (they would be at 50% on the charger), thanks for asking though. Second I was going to disconnect the wires on the solenoid and starter to clean them up. I tried to loosen the small nut and outer shell cracked off. Now before we get into my breaking everything I touch I barely put any pressure on it. So, I know I need that.
The batteries are odyssey pc1500 red top.

There have been two cases that I've seen a starter short out internally. if this happened, it may very well be draining your battery and cutting all sorts of power to other things as well. Sorry to hear you've got the fingers od death today...i'll keep my truck right the hell away from you!! just kidding. ANyways, did you happen to find where that noise was coming from?

Not yet. I called it a night. I'm gonna pull the starter and go from there. Thanks again for the help. The internet might actually be good for something besides porn. I know that's crazy talk. Thanks again I'll keep everyone updated.

any updates on this?

Oh, the suspense!! :D

I know...i wana know what it is just incase i experience it.

Here I am, cold and a little wet. Starter is in, no change. By the way, in my haste I may have left a glow plug in on drivers side behind the steering shaft. So, I misinformed you yesterday when I wrote there were no broken glow plugs, because there is now and I can't get the darn thing out. I am charging the batteries again. The one on the passenger side was almost dead. Once that is done I will see if it turns over. This is all I have for now. I'll try to keep you more up to date. Thanks

P.S. tomrex I may have to take you up on your offer tomorrow or Fri. I promise I won't touch your truck. hehehe

if you broke off a glowplug tip in there, DO not try to start it. That little bugger is sitting on top of the piston and could do more damage yet. if you just twisted off the head of it and the rest is still threaded in there, you're still ok to crank. Let me know, I don't have to be in to work until later in the evening. :)

I just twisted off the head. Put some liquid wrench on and letting it sit. Thanks

phew. thank god. That can get disastorus (sp) quick! Batteries up yet?

I am slow charging them. They have been up and down a lot the last couple of days. I think I am just postponing the inevitable. I still got to get that plug out.

I have to surrender, I need to get this truck in and fixed by a pro. I live just south of Chicago and need to find someone or some place that is reputable. If anyone has some suggestions please let me know.

You want me to stop by and take a look at it?? It doesn't hurt, and worst case scenario, it still has to go to the shop.

Dan, next course of action...if you really want to know is to pull the oil pan off and find out what smoked itself. For everyone else, turned the motor backwards, by hand, and then hit the key. Turned a half a tun and stopped with a clank in the same spot. No fun, sorry man. :)

Trade it in..these trucks suck....mine was doing that also after idling I never found fuel in my oil and it never had power lose but it would sometimes some a bunch at idel after a while....then my glow plug fell in the #8 cylinder at 101000...well see if GM honors the warranty...they want 1000 just to see the big picture...


Go Dodge...

Duraquez

What?? Nobody dropped any glowplugs in the motor! Some are good, some are bad - that's the way it goes. Trust me, there are bad Dodges, Ferds, and Yota's too. I've had a few Cummins trucks, two were good, one was bad. :)

Hey, Thanks for coming over and giving me a hand.

Not a problem at all, wish I could have helped more. Did you wind up pulling that pan off, or are you going to leave it to someone else?

people like you piss me off

Yeah no shit. Dont come to a mainly all duramax forum and talk smack. You get a defective truck now and then, dont tell me dodges never have a problem either. I dont see how a glow plug would drop in the cylinder unless it was snapped and left there and maybe rattled its way down the threads. Mine has 95000 and recently had injectors done by WARRENTY and I didnt pay nothing, it has a ppe level 4 tune on it now and it runs great. Dodge-a quick, evasive movement, as a sudden jump away to avoid a blow or the like. Its in dictionary, look it up. Btw dodge trannies were never really any good in the past but I dont know about now. I wouldnt chance it. No disrespect to any other dodge owners out there but just this jerk off.

I don't care if they want to bash GM products, do it in the right place. This poor guy's got an expensive list ahead of him to get his rig back on the road. The idea of forums is to give people a hand when the need it, when you can. Talking shit is part of it, but be a man about it...don't smack someone when they're down. Go pick a fight with someone who has something to fight back with.

I would first try to look and see if there is anything on the front end that you can look into. The water pump, oil pump etc are all gear driven off the front end. You could look and see if you have the shear pin problem which in theory could get the valve train off time. I think if you do a search there are pictures and instructions on how to remove the crank position sensor and try to wiggle the gear inside. At this point with the knock and the fact the starter won't turn it over, I would not attempt to start it anymore unless you can confirm that its not trying to eat a valve.

Read back. Locked her up tighter than a drum now. We got the engine to roll backwards by hand a half a turn or so by hand - then turned the key, rotated back to original position and stopped with a clank. There is no turning it back or forwards now. Broken rod or a bomb went off. Either way, it's no fun.

Time to find a motor from a wrecked vehicle. Possibly even an lly with low miles with improved injectors. Search for the thread where Rick Delance converted one of his lb7's to an lly. Save your money on tear down and inspection and just re power. BTW I think the starter solenoid was damaged from the torque of the stater and the impact of the bendix/drive gear slamming against the flex plate, which had become the immovable object.

Starter's brand new...even if the bendix was stuck in the flywheel, you should be able to turn the whole kit and kaboodle backwards!

Wow! I would love to know what locked it up.

You may want to ask what Mvnvltn's motor did. I think he had shear pin problems as well.

my bet is on a sheard cam pin..

I'm betting on the torque converter. I was watching this thread because I had the same thing going on. Even posted because I thought it might be head gaskets, injectors, or glow plugs. I found the problem tonight! I pulled the wheel covers and while I was listening for where the noise was coming from the motor locked up and the torque converter busted a hole through the bell housing.

That's not normal... Any pictures of the carnage?

My guess is, there is some fluid in the cylinder that the glowplug is broken in and that is what is causing your lockup. Get that glowplug out then turn the motor over by hand if you can...but don't force it.

I heard it in person. After i got it to roll backwards, turned the key - it turned just as far as I turned it back and stopped with a mechanical clank from the bottom end. I didn't stick around to pull off the pan, but my guess is a snapped rod, now jammed in a tight spot with the crankshaft.

When I locked my motor up tighter than a nun, it would just make this nasty "EERRRRRRRR" sound. Once I removed ALL the glowplugs she turned over by hand pretty easily and shot oil out both rear cylinders.

Just seems alot easier than pulling the pan off and looking at this point. Also, he said he was going to take it to a shop of some kind...I would imagine they would rather him not pull the pan and start taking this truck too far apart, because at that point I can see them charging him more to "find" his parts.

Here is the carnage......:(

WHOLLY CRIPE, what were you doing to that thing?? I've never seen that before...too bad there's a first time for everything. :( Sorry man.

Engine was at idle while listening to driver side when it went.

I put some pics in my garage if you guys are interested.

Any word from Mongoose on what his problem is?

Nodda peep.

My son bought this truck. It looked like one bolt fell out of rod cap. The other one then snapped off. No damage to block. Crankshaft is crap.

Sorry feel for you Mongoosefun, Had same thing happen to my '01 last fall, just quit and had same situation, wouldn't turn over, found it had dropped valve in #3 cylinder. At first figured on rebuild but ended up replacing engine due to cost of parts. I do have complete set heads for LB-7 if you should need some [been thru machine shop and checked after purchase] that I bought off guy who had cam bearing go out in his LB-7 and he made mistake taking to dealer with his programmer still on truck so they denied all warranty on engine with 40k. Good Luck!:(
