Hot No Start Please Help
ok late 04 I have replaced hpop, ipr, icp, d-plugs, Stand Pipes, j-tube, nipple cup orings and pulled injectors only found one that has a bad inner seal replaced it. truck starts great cold but still have a Hot No Start! My thought is i may still have a bad ipr. When hot at idle i have seen 544 psi from hpop and 70-80% ipr when i was driving it the other day at 3,000 rpms i was in the throttle a little i had 1461 psi from hpop and 83.9% from ipr. once hot shut it off then try to restart i have 479 psi from hpop and 83.9 from ipr. This leads me to feel that my ipr is bad, i'd like to test it but not sure if there is a way to test the ipr sensor? Any help would be greatly appreciated cause i've about lost my patience with this!
