Before you pull the IPR Get the Idle and 2500 rpm Info
So you have to Crank Each time Cold 3 times??
SO you must fill the system each morning type deal??
and Does it Misfire upon Warmup??
If so it could be possible a Injector Oring going out or honestly any oring throughout the HPO System could be failing and draining
or even the HPO Pump could be Failing your IPR% Is very High for IDLE

I will do that tomorrow. And yes, when I go out in the morning to start the truck, it fires right up, it doesn't misfire or anything like that. Truck will run completely fine till I shut her down. Then she usually won't start till the next morning. And yes hahaha I twisted my shaft. I went out to start it one morning and it would barley start and it would run super rough blow white smoke like a forest fire, and it ended up being the shaft twisted making everything off timing

I have a 2003 6.0 that's having a hot start issue and was wondering if anyone can help me out. I have a scangauge 2 and these are the readings I have. It will start in 3 cranks when cold and the icp is at 1200 psi and ipr DC is at 50%. Hot idle is icp 790 psi and ipr DC is at about 27%. Then when I try to hot start it icp is at about 390 psi and ipr DC is 84.7%. But what I don't understand is the truck runs completely fine and at wot icp will jump right to 4000 psi and ipr doesn't go above 65% DC. Can anyone have any ideas what's going on here?

So Far the IPR is the most likely culprit IMO
I get mine from top I just pull turbo I can get my hand in there from bottom plus I have lift
you can get IPR turbo On probably take longer fighting stuff in the way though
I have changed ICP with turbo Installed But you ICP sensor seams Good guess more to the point it can be worked on turbo in place
