Running with ipr unplugged
I have a 96 ford 7.3 and recently put rebuilt injectors, new ipr,icp sensor,pcm and a few other parts on it. The truck starts right up but blows alot of white smoke and after a few minutes the check engine light comes on and starts running really rough. Had it hooked up to a computer and found that the fuel pressure goes to maximum within a few minutes of running and that's what I'd throwing the engine light on. We unplugged the ipr and it starts right up so the guy said it is the high pressure oil pump......any thoughts on this assumption?? If it matters the oil pressure sensor is buried on low till you give it some throttle then it goes to normal so it could use a lpop.

About 20 miles on the injectors and I had a scanner on it the fuel pressure is around 350 then after a min or two it spikes to 3500

I'm not so sure about that because it was a $9,000 computer he plugged in and I seen it with my eyes that the fuel pressure went to 300 psi that's why he was thinking bad hpop because we unplugged the ipr and the truck still runs so he was thinking something internally must be bypassing the ipr

Icp is new and ipr is new. That's why he is assuming hpop because he said it should go into default with the ipr unplugged
