My problem started yesterday when my 03 3500 quit running yesterday on the highway, bad enough we had to haul it home. I automatically started thinking it was the fuel jelling up (the temp was about 5 degrees). So I put it in heated barn and let it thaw out. Drove it about ten miles and it started doing it again. In both cases it simply sounds like it's running out of fuel; start sputtering and missing real bad and then will slowly die. It will sometimes restart, others not. I will guess you guys are thinking it's the lift, but it can't be I replaced that with a FASS a few months ago. Alright, here is the kicker I did the key thing 3 times and that showed code P0234, which means the turbo was overboosted. To me, the problem I am having and this code don't seem to match. Any info will be of help.

 

How many miles? Is it still under warranty?

 

Did you try a fuel filter???

 

78,000 miles on it and it's still under the cummins warranty. and i just changed the fuel filter about 2 weeks ago

 

My 95 is doing the same thing! It was around 5 degrees here in Ct. last night and I woke up an the truck started fine but had the same exact symtoms as yours. My cure is going to be to change out the fuel filter and this time put some sort of fuel tretment in it. I forgot to do it,first time in thre years I owned the truck!

 

my threw a code once that sent it into limp mode, i think it was turbo related...but im not sure which one.

the code might however be totally unrelated. try clearing it and see it if returns

Good to see someone understands you dont start replacing sensors and what-not everytime you see a code.....troubleshoot.

 

I agree to that

 

I finally limped the truck to the closest dodge dealership and showed them what is was doing. This was on a friday so it sat until the nest monday. They put their tester on it and it did not show any codes. The technician drove it over 40 miles with no issues at all. I should mention that the the temp then was 40-50 degrees, not like 10 degrees before. To me this makes no sense that before it would barely run now it runs fine.

 

are you using any type of anti gel additive?

 

I was not running an anti-gel the first time the truck messed up. After thawing it out I did add some. The funny thing is my dad and I buy our fuel from the station and he ran in the same temperatures and he did not have any issues. After it originally happened I automatically thought it was gelling because my FASS pump seemed to really be struggling to push it through.
