7.3L Quiting while hot and not restarting (it's not the cam sensor)
Truck is a 2002 F350.
First time it quit on us going to the airport coasted to a parking spot and left it a couple days. It cranked right back up and drove a bit and quit just like the Cam sensor problem, it has the new sensor in it. We bought a new sensor of course and replaced it with zero change runs till hot then quits. A mechanic we trust suggested it was the fuel lift pump so we replaced it and it ran for 300 miles just fine and is now acting the same as before. I'm buying a fitting today so we can check the pressure at the filter housing to make sure the new pump is holding pressure. The truck is not throwing a single code.
Parameters when trying to start hot:
ICP floats around 185 +-5 I know this is low,when I unplugged the ICP sensor it went well above 1000 I think it was 1500 plenty high enough for the ECM to think it should start, no parameters changed besides the ICP pressure
IPR demand I think was 15%
Injector pulse width is .6ms
More facts about the truck: We just cleaned the IPR even though when cold it cranks and runs perfect, checked the ICP sensor by removing the plug from it with no change.
