03 6.0 No Start
OK, I have an early '03 F250 Crewcab 4x4 Automatic with a 6.0. It has an Edge programmer that I normally run on 3, 4" MBRP exhaust, and a 4" lift with 35's. Otherwise it is stock.
I just had a HP oil leak this last March and replaced the HPOP, IPR valve, ICP sensor and all o-rings on the injectors including oil rail. The truck has run better than ever. I have only put about 3k miles on it since then. When I towed my toyhauler it did great.
About a month ago I noticed a very slight hesitation in the idle, but it didn't even show on the factory tach so I didn't think anything of it. A week later it didn't start after a long crank in the parking lot of Lowes. I waited a minute and tried it again and it started right up and drove fine. A few days after that on the first colder day here (40 degrees) I tried to start it and it just cranked and cranked. I have been super busy so I haven't had a lot of time to work on it. I plugged in my scan gauge II and showed no codes. When I crank it over the ICP is only showing 20-35psi. I thought maybe the IPR was sticking so I put in a new one. When I pulled the old one the screen was pushed in and torn. I figure that was the problem and put the new one in. No change. I am a bit frustrated after such a big tear down only 3k miles ago and now it's down again. The parts I put in then were all International parts and like I said it has run great up until now? I notice the factory oil pressure gauge doesn't move while cranking. Should it? Where can I find out the low oil pressure. I'm not sure I have LOP for the HPOP to pump, but I also figure that would have put up a code or two.
