Questions
Possible for a bad ipr that forscan is showing 65% closed but actually is open and sending oil to crankcase while cranking motor? Also can a good lpop keep up with a hpop with a bad ipr? Seems hpop reservoir remains full if I physically top off and let sit but after cranking motor reservoir empty’s. I would think a bad ipr should still pull some oil pressure and not zero.

With a dead IPR coil, you should see about 100 - 200 PSI on ICP
if HPOP res is empty after cranking, then you have a LPOP issue, low oil level, stuck pressure regulator, cracked pick up tube, clogged pick up tube

I came across something late last night...could have been this morning. I also don't remember al the details of the thread, but... I saw a mod on one of the forums mention one time the top injector seal, possibly the metal ring failed causing the system to not build proper pressure to fire up

@robjs111 hate to bring this back to the top but did you ever figure it out? Would like to know what the outcome was for the memory bank. I seen it's been about a month since you logged in.
Thanks🇺🇸🇺🇸🇺🇸🇺🇸
