No Start but has 1400 PSI

[6.0 KingRanch]

My 2006 6.0 diesel had a high pressure oil leak. I tore it down and found bad o-rings on the d-plugs so i replaced the d-plugs, stand pipes, even bought the master o-ring kit from victor reinz and did almost every o-ring you can think of. The HPOP also has the updated STC fitting already. I have read every article know on the web. I have AutoEnginuity w/ ford advanced software. I also have tried disconnecting the ICP, fan clutch, belt still no luck. The ICP reads 1408 PSI when cranking and IPR is 54% also CMP and CKP show a value of 1 which tells me theyre in sync. FICM V is 48 and batteries are BRAND NEW and also using a battery charger so they dont die. I need help and Im stumped. I do get a code P2280 ICP circuit too low which is odd but i cant seem to find any wire chaffing and not to mention its an 06 which didnt have all those prob the 03-04 had with the harness. I live in central FL and do not trust Ford nor any other shop to have them tell me whats wrong. PLEASE HELP.

Also I have 56 PSI fuel pressure and no blown fuses. Anybody??

There should be 2 sync readings one for the cmp &ckp and one for pcm to ficm sync.
Other than that you should be starting if all readings are as given.

Does it pass the injector buzz test sounds to me like multiple bad injectors, Any smoke while cranking, any codes

ok so after all day of trying multiple things i came to realize my icp showed 1400PSI but my icp Voltage on the other hand showed 0. so after extensively tracing wires down i found that culprit to be a bent prong on the icp itself which caused the ficm to think it was unplugged even though it was physically connected which gave the false icp psi reading. now the new reading is a big fat "0" for the ICP PSI. i guess my next step is to do an air test to rule out any leaks even though i replaced d-plugs stand pipes and inlet and outlet o-ring for hpop, plus o-ring and screen kit for the ipr. any other suggestions? would the icp read at least some sort of pressure even if it had a leak somewhere. if the ipr was bad and not closing like it should would that cause 0 psi and also a bad hpop would that also cause a o psi or would you still have some sorta pressure with those bad as well?

all injectors passed and no smoke while cranking

If the IPR has failed fully open allowing the HPOP output to drain back into the pan you would get no oil pressure to the oil rails. It would be dumping as fast as the pump puts it out

What is the IPR duty % now that the ICP is plugged in

IPR is 14.84 with koeo and 84.77 while cranking. but i have read somewhere that those values are what the ficm is telling the ipr to do and not what ipr is actually doing. is this true?

ficm sync is also a value of 1 while cranking
