No Start After Headgaskets w/ ScanGuageII

Hey guys I have an 05 f250 harley edition. I just finished doing headgaskets after the previous owner put black onyx gaskets in it, when he deleted and studded the truck. The truck ran fine before teardown, besides the blown headgaskets. About 4k miles before i bought it the previous owner had ford put in a new hpop, 8 new injectors, STC fitting, and new stock replacment turbo. After buying the scan guage and seeing my IPR reading was 84.5% on crank. I pulled the Ipr and saw the small piece of screen misssing from the old oil cooler screen blocking it. After reinstall the truck fired as soon as it built oil pressure, but it was really cold that night and when it tried to go into high idle it started running rough and i had to cut the truck off bc i saw smoke which was just from me cracking my cac tube. Damn plastic tube. Now it wont refire. I pulled the IPR again but it had no trash on it but my reading is back at 84.5%. ICP is hitting 500psi and trying to start and the pressure continuously climbs.

My question is could the IPR valve be bad and when i took it apart and physically moved the plunger it started but has down frozen up again? Or could the sensor part be bad and by luck it started that one time? Based on the fact the hpop, updated stc fitting and oil cooler and all is relativly new and wasnt taken apart during the gasket job, why or what could be leaking...

Ipr reading 84.5 at crank
ICP 500-2xxx something psi as soon as it hits 500
FICM Main Power 49.5-50v keo
I have logic and crank and cam sensor sync
I also have enough rpms to start

Voltage at crank in the 10volt range ? Need 8 volts for FICM to come on.
The crank time will over time come up to 85% on IPR.
But the IPR can be damaged and causing the problem.
