hpop or stand pipes
trying to figure out whats wrong with my truck. ran good all day, shut it off and would not restart. no codes. when using the scanner is see that im only getting about 375-390 psi(at icp) i know it wont start below 500. i let it sit for a while, about 4 hours and it did start but after shutting off it would not start again. for some history it has been kinda cutting out at high throttle like when passing someone, it also started kinda funny for a few days, almost like it wasnt getting enough fuel. i have a new ipr i was going to install tonight but dont really think its the problem. any suggestions on where to go and how to tell if its the hpop or stand pipes would be great. thanks Brian

I would check the IPR first then air test the HPO system to see if you have a leak. What's the IPR duty cycle (%) while cranking? Also, since you're getting some ICP then I'm thinking leak before HPOP.
