2003 6.0 dies then hot, no restart???
Heres the story, I have a customer bring me a 2005 F250 with a 2003 6.0 engine in it. His egr cooler failed and I drained about 3-4 gal of water out of the crankcase. He said he brought in from a trip and the next morning the truck wouldnt crank over (because of the water on the pistons). I deleted the egr cooler and it ran perfect for about 20-30 mins at a idle and when I put it in gear it died and wouldnt restart. Once it cools down, it starts right up. I once again started it and let it run and it will die once it gets so hot. I put my scanner on it and monitered FICM voltage, ICP and IPR. Ficm voltage is perfect but the ICP reads about 100 psi while start while it is commanding 650-700 psi and the IPR goes to 100% duty cycle. So I am assuming I have a high pressure oil leak. I end up replacing the HPOP, oil pump cover, the line off the pump, flex lines under the valve covers and the IPR. I start it and it is doing the same damn thing. I thought too that maybe the ICP may be a issue since whoever installed the 2003 engine in a 2005 truck had to extend the ICP harness to the rear of the engine. I unplugged it to which it should default at 650-700 psi and which it did so I assumed it was good. I am at a total loss here. I work on these trucks everyday in my little independent shop and I have never had a issue like this that with these symptoms these parts dont fix. Where do I go from here?? Any help is greatly greatly appreciated. Thanks
