[QUOTE="golfer, post: 774251, member: 266"] yes. The factory HPOP is a piston pump..so they have very tight tolerances. 40-50psi cranking "ICP" pressure is just your LPOil pressure...so your HPOP is literally dead...not 'weak'... further..since you are seeing SOME kind of reading for ICP...that means you have LPOil pressure...the HPOP&LPOP just happen to be the exact same...since the pump is just sitting there as a vessel. you could have spun the inlet/outlet plate inside the pump...your could have grenaded the piston housing/barrel...broken the shaft, or any number of other internal mechanical failure. but you can rule out the IPR...if the IPR were bad, you'd see (depending on cranking rpm)...(up to about) 275psi..still a no-start...but anything in the 200's could be indicative of a bad IPR...anything under 100psi, and the IPR is probably not the culprit.
