alright, so we have an 04 dually with a piece of **** 6.0L... it takes 3 times turning over to start. once it get running as soon as you accelerate it dies... again, again, again... after about 20-30 minutes at idle it runs fine. then once ur goin down the road it dies, it may run for three hours just fine and then just quits. starts right up fine and then once you get goin it dies< even at high speeds and under loads... can any of you help?

Im not a tech, but mine died randomly on the highway and turned out to be a High Pressure Oil Switch. The injectors need high pressure oil to fire, and if it isnt getting it, your truck wont run.

Ya know, I guess I got a good one, bought a 2004 with 41,000 now has 72,000 haven't had one issue.......been running Motorcraft dino 15w-40 just changed to Mobil 1 diesel 5w-40, you wouldn't believe how much easier the engine turns over and starts, motor is quiter and the turbo spins quicker

Its either your cam sensor going bad or your high pressure oil pump. I had my high pressure oil pump die on me, in the drive thru at stake in shake, it was a costly repair. Try the cam sensor first its cheaper.

thanks for the help guys, this truck has been nothing but hell. typical 6.0, first coolant in the heads, then egr, then blown motor, new motor, another egr, and now this... we did the censor... that isnt it. guess well check the hpop

cam sensor on 6.0 dont go out , if this truck has no codes it sounds like two things to me , fuel pressure or maybe an icp sensor , need to get a scanner on it and see what it doesnt have and run a fuel pressure test
