I haven't been reading much here lately, my truck had been running perfectly until tonight. I got in it started just fine, backed out of driveway and made it about 1 ½ blocks and it died. I rolled to the curb and tried starting it, it would crank a little then start and run for about 4 or 5 seconds then die. I let it sit for about 20 minutes then tried it again, it started and ran for almost 30 second then died again. I have about 45 miles on it since last fill-up. I always get fuel at the same place. The outside temp. was about 28, and I know it wasn't jelling. I have started the truck at -25 and never had problems. It didn't show anything in the DIC. I have worked around and worked on Diesel Equipment for the last 25 years and it was just like I had ran out of fuel. I drove it yesterday and it had got down to 26 the night before. The will call the dealer in the morning. Is it possible that the fuel lift pump went bad. Yes this is Wyoming and the weather can change real quick. In the last 2 weeks I have seen 80 degrees, 12 inches of snow and then it got down to 23 degrees. In Wyoming if you don’t like the weather just stick around for 15 minutes. Summer is the 4 days skiing is the worst!!!!
:help:

i saw this once with my truck. all i did was open the gas cap and let the pressure out. then it started right up and was fine. something with the sudden change in temperature created a vacuum keeping the fuel from running through the system.

the other thing i would check, is the priming of the fuel filter. they have found some fuel filters with tiny pin holes on the bottom of it, causing it to lose prime. look into this as this may be your issue.

good luck and let us know how it turns out.

BIGMoe we are in the same boat weather wise. It has been in the 70's and now 26F.

Maybe they stopped blending your fuel do to the warm weather? Now the cold hit and you have fuel problems. Even though it is not gelled it could still form ice. Maybe at the pickup or on the filter face?

You need some Power serviced 911 ( red bottle) . Maybe a filter change? Do you run an aftermarket filter without a filter heater?

Remove the bleeder screw on the OEM filter head and pump? Is there fuel there?

Bronco, You may be right about the fuel filter. I just got a call from dealer, they picked it up this morning. They have 3 Duramax's in with the same simptons. All of us filled up at the local Flying J. I am still healing up from major back surgery so I didn't really feel like messing with it. I had to walk back home, and "that was work." The dealer said he would let me know what they find as soon as they get it in. The fuel filter was just changed about 1000 miles ago, and I do not have an aftermarket filter. I do run Power service 911 when it is really cold.

Just for your information, my wife and I are die hard Bronco fans. And I just seen what your weather is like on Denver TV.

:mad: :mad: :mad: :mad: Just got back from the dealer, the tank had about a quart of water in it. They had to remove the tank and drain it, and replace the sending unit. The water froze and messed up the plastic screen on the bottom of sending unit. I contacted Flying J and they told me they check their tanks daily and haven't seen any water present. If they have any more complaints they will let me know. It is kind of hard to prove were the water came from although the last 5 tanks came from that Flying J. :mad: :mad: :mad: :mad: :mad: I guess it sucks to be me right now. By the way there was quite a bit of rust in the bottom of the filter houssing. the element was only dark on about the bottom 1/3.

BIGMoe >Water in fuel not good ! we have had the same weather here in the northeast. This is the worst weather you can have for water condenseing in a tank or on any metal that might be cold. The other day here in VT my tractor,in my equipment shed, looked like someone turned the water hose on it and it's been in the shed all winter. It was about 70 outside so the air was warm. I had to open the big shed doors just to get some heat inside to dry out the tractors. This time of the year I try to buy fuel at night when it is still a little cool as it comes out of the ground still cold even on a hot day, Thus; It could condense water in the tank on a hot humid day. so it is hard to say where the water in your tank came from.

BIGMoe,

Would you happen to have receipts from those last 5 tankfuls? I would really push them for payment of repairs by filing a claim!! It must have cost you some real $$'s :mad::mad:

i will let u know that even if there is water in their tanks their not going to admit it because it would mean big trouble for them. i should know i worked at a fuel company

I personally wouldn't run Power Service 9-1-1 as a regular course of action for anything but emergencies. It does contain alcohol as quoted directly from their web site, "Contains the type of non-harmful alcohols recommended by diesel engine manufacturers for removal of water in diesel fuel systems". They even make it a point to state "Diesel 9·1·1^® , as its name implies, is the product diesel-engine operators call on when they have a fuel emergency." In an emergency is one thing but there are better products to deal with small quantities of water and lower the clouding point which do not contain alcohol. Somewhere on this board are posts referencing GM's no alcohol in the fuel system position, but I'm too tired to go search for them.

WIF sensor never went off? Guess those never work, surprised they keep putting them on these trucks. Don't think I ever heard of someone having theirs go off.

There was only about a tablespoon of water in the bottom of fuel filter. I condition would of been warmer, it may have got enough into the filter to set off the WIF. My dealer did me a favor and did the fuel sending unit under warranty as I had complained about the gauge not reading right so all I really had to pay for was the new filter and some trouble shooting time, and towing it to the shop. My insurance will cover that under my roadside assistance. Glad I didn't have to pay for the whole thing. I will end up having to pay for 1 1/2 labor and the fuel filter.
:) I am fortunate to have a dealership that appreciates their customers, and treats them right. It could of cost me a lot more. :)
:beerchug: I will have to take donuts next week. It pays off for me!!!

glad to hear it wasn't anything major and you were taken care of. do you use any additives? if not, may be time look into using them.

NCMIC, I do use Power Service in the colder months. I brought up fuel additives to the Tech that was working on my pickup. He gave me something to think about. I asked him what I should use to keep the rust from getting into my fuel filter. He said that is the purpose of a fuel filter is to catch things like that. He said if the service stations would keep their fuel cleaner it would help more than anything. The rust and crud isn't being formed in our tanks it is coming from the stations. The additives are not going to eat the rust and crud and make the fuel clean. Some do make the crud fall to the bottom of the tank, but the only way to keep the fuel cleaner is better filtration. I do plan on installing an additional filter, and most likely it will be a "Nicktain". I am also thinking about adding a electric fuel pump close to the fuel tank. The way The General has the Duramax set up I don't feel is the best as far as fuel delivery to the engine.
