Won't start when hot. New IPR, New oil
My 7.3 won't start when it's hot. It would only build 2-300psi of high pressure oil. Tried cleaning both of the IPRs that I had and finally replaced it with a new ford one this morning. Has 11 miles on an oil change (did the same thing before changing the oil too).
Before putting in this new IPR I had codes for the high pressure oil pressure above desired and at idle it was ~2700psi at 8.2% IPR dc. Seemed to point to a stuck IPR. Since replacing it I haven't gotten any codes, but now it still won't start (I'm guessing I'll have some new ones once it does start though).
Where do I go from here? Chase down IPR wiring? Lpop?
