[QUOTE="haligen, post: 1509275, member: 19816"] A manual gauge in the reservoir plug hole shows 40psi cold. I'll assume that the LPOP is functioning as it should. I double checked all the wiring, getting battery voltage to the IPR connector (which is new) with KOEO, then I made a quick pigtail harness and went directly to the battery. No change in HPOP pressure while cranking. I need to get a 4k pressure gauge to check the HPOP manually. Right now I'm using a spare ICP sensor with an adapter to fit it to the HPOP discharge hose.
