04 6.0 Hpop pressure problems!!!
Im working on a 04 F-350 with the 03 6.0 it had quit and i check and it had no High Pressure so after replacing the IPR then The HPOP and ICP i have only 235psi then i took the valve covers off and pressure tested the system and found #1 injector blowing out- replced it the tested again i cant hear any leaks yet i still only get around 235-260psi it did jump to 400psi then i heard something blow out the pressure and it was back to 200psi any Direction would be VERY Helpful

There are d-rings in the top of every injector.
I know you replaced the HPOP but did you check the oil tube that feeds from the pump to the block? It can rub the HPOP cover and develop a leak there. There is an updated cover for them. Other than that I would say you need to air pressure check the system. Remember....you have to apply 12VDC to the IPR to close it but only for a very limited time. Something less than a minute IIRC.

Not as far as I know. The connector is the same as a 7.3 injector connector if you want to make a pigtail. If you want to purchase one it's about $12.00: IPR or VGT solenoid connector 6E7Z-12A690-DA 1878512C91

The IPR gets a 12V constant on the red wire when in Start or Run. The PCM controls the duty cycle of the valve by switching the ground(Yellow/Red). This switched ground is pin #2 in the center PCM connector. Verify with a test light on the IPR connector if you're unsure.

Put pressure on it this time i back to the drivers side oil rail and there it was #8 injector and when i pulled it out, the bolt thru the wire harness on the injector was broke in half so i replced that injector and we will see tomorrow if that solves the Problem Thanks Guys for all your help
