white smoke and wont rev past 2500

Well i just got this thing running a few minutes ago after it quit out of no where. ran fine up until that point.

I replaced the cps, idm, new fuel filter, checked every fuse, oil is full, hpop oil is full, putting out good fuel pressure.

now... It wont rev past 2500rpm and if i rev it that high it blows alot of white smoke. every now and then it sounds like it wants to stall too.

any ideas would be greatly appreciated. lol this is my first diesel and ive only had the truck a little under a month.

What color is the fuel in the fuel bowl? If it is dark colored or your filter looks dark(black) then you may have bad injector o-rings. Put it on a scanner and see what the duty cycles are and psi readings on the high pressure side are and post back. You could have a bad ICP. IPR, HPOP could be going. There are many possibilities here.

Re: white smoke and wont rev past 2500

sonds like somethin else may be goin on but you know theres also a screen in the fuel bowl that needs cleaning,on the drivers side of the bowl you will see the hole with the screen in it.you may be able to just scrape it clean but if you want take it out to clean you need to remov the fpr

Re: white smoke and wont rev past 2500

alright well my buddy just brought his edge evo over so we could use the scanner it has. shower a cps code, some kind of exhuast code. cleared them ( i replaced the cps). Still did the same thing

Well we put it on the 3rd level on the programmer and the thing ran perfect. reved up past 2500, no white smoke, and idled perfect.

lol, any ideas?

Re: white smoke and wont rev past 2500

The programmer is now telling the PCM to deliver more fuel for a longer period of time which means in stock for it wasn't getting enough fuel. Sounds like a fuel restriction to some degree. The exhaust code may be the EBPV code for a clogged tube or broken sensor. When you say after clearing the codes it did the same thing do you mean that the cps code and the exhaust code came right back? If so then you still have a problem with the CPS and should be looked into more thoroughly.

Re: white smoke and wont rev past 2500

both codes stayed off. the one was just a exaust back pressure code.

I had travis dykes (awsome dude) from 2L motorsports hook his computer up to it and every checked out fine.

He told me to try a diffrent idm. That maybe the one i have is better then my last but still not all there.

If not that, then more then likely injectors.

Re: white smoke and wont rev past 2500

What kind of mileage do you have on your truck? It could be injectors or injector o-rings. It most likely isn't the IDM if you changed it out and it still did it. The likely hood of two IDM's being bad is fairly uncommon.
