So today got a no start when hot on this new motor that only has 30miles on it... cam sensor is new, icp sensor is new. I know its bad but i have to spray ether to get it to fire and start.
when cranking im getting icp 300 psi with 652psi desired...ipr duty cycle was 80%
when engine finally started, i test drove it and on a straight away at WOT its getting 2100psi which is low right? I mean its struggling to get to 45mph. Engine builder recommended ford or rotella for break in. Oil level is good but man that oil looks thin as hell.
I reused the old hpop because it was “supposedly” new right before the old motor went bad.
Get you a ipr adapter and do a pressure test to clarify its your hpop. Could be other things. It's nice to be sure instead of throwing parts at it. Cheaper to.

I did notice the trans is having some trouble shifting it goes from 1st, 2nd, 3rd and skips 4th and goes to 5th eventually to 6th (MANUAL?) and when it comes to a complete stop it goes to 3rd. It struggles to get out of 3rd too like rpms are up and everything. have to reduce throttle to get it to shift to 5th.... Is this my fraking issue?
I just opened your attachments in the post above. Your ICP pressure is the same as ICP desired, so I do not think it is an issue with the high pressure oil system or HPOP - since the IPR % duty cycle is far from maxed out at 1750 psi. The ICP sensor voltage also matches with the pressure.
As in the PM's, fuel pressure would be the next thing to verify (at WOT).
Mark is of course right. I started from this picture, it shows a too low ICP
Thanks for the post Hartwig! Since I have a few PM's from him, I hadn't opened his first attachment. Clearly that shows an ICP that is too low to start (and it shows a desired ICP less than actual). That is interesting since he can clearly start his engine now - just under powered at WOT. I need to re-visit all of his PM's, but from those, and the most recent two attachments, it looked more like an issue with fuel supply. I think that the last two attachments are after replacing the IPR valve, which may have corrected his "initial" low ICP issue. He is getting a fuel pressure gauge - hopefully he will gave it installed tomorrow.
Did test today at jobsite and i have 50psi of fuel. Driving and at idle...going to do air test with valvecovers off. But im starting to think my hpop is dying
