Ok guys well I'm new here and i tried to look for a post that might help me out with what I have going on, if I missed it I'm sorry. I just got a 2004 dodge ram 3500 cummins has 180k on it, ran good when i first got it. Had it almost 2 weeks and was making a 3 hour drive to south Florida. I was on the interstate for most of the way and truck didn't really give me any problem. Has soon as i got off and stated hitting red lights and all the stop and go the truck was having a really hard time getting back up to speed. Went along for maybe 4 to 5 more miles. Then it decided it didn't wanna run anymore. so it died..... I had it towed to the shop and they said it wasn't priming up. so they put a new "lift pump" is what he called it then it started priming. well then it would start but only run for about 10 mins then it would die. and if started right after it died it would then run for only about 45 sec. They said it was the "cp3" pump so that got replaced. Still same problem run for 10 mins then die. Long store short they've replaced the lift pump, cp3 pump, fuel pump, fca, tps, fuel pressure sensor, and they tested the injectors while inside the truck and now tested them out side of the truck..... does anyone know what it might be?????PLEASE HELP ITS BEEN 2 MONTHS...

 

Did you figure this out? Having the same issue after lift pump died.

 

7 year old thread, and that is his 1 post..... You would be much better off, starting your own thread, tell us what the problem is, what troubleshooting you have done, and any parts you have replaced.
