CEL on? Check the main oil level. Take off the oil cap and smell for burned wiring smell. Check the IPR wiring really well and see that the IPR solenoid coil nut is tight. Check the fuel pressure when cranking. Cheers!

O ring would smoke a lot wouldn't it? There is no smoke and oil is brand new, everything acts as it should, just don't fire on its own, and won't stay running without constant throttle

Ok smoke a lot if the o-ring that separates the high pressure oil from the fuel is bad, the high pressure oil goes into the fuel and back to the fuel filter and tank, this may cause a blueish tint to the exhaust, you're burning the oil and fuel together. You we also be using oil.

How black was the fuel filter , old dirty oil black with broken o-ring to boot.????

I would also check the IPR as mentioned before. I believe you have low high pressure oil pressure. Could be bad o-ring on the IPR or it could be stuck.

I hope someone with more hands on can jump in here and help out.

Good Luck

Its a IPR issue man. easiest way to check without taking it out is if you have a spare injector harness clip laying around (same thats used for the IPR) connect 12v to it and connect to ipr. listen closely if you hear a click its only gonna happen once.

if you dont hear anything buy a new IPR valve.

I had the same issue with My 7.3s... been there done that!

pull out 140 from the bank and order a new guy.
