you should check your electric fuel pump pressure, your mech. pump is new so its probably ok. double check that tho. inspect the stand pipe o-rings i would replace as necessary.

If you are doing injectors, I would replace the stand pipes - the new ones have the upgraded o-rings. I would also replace the dummy plugs and put in the one piece fitting on the HPOP discharge (replace the STC fitting). Sometimes low pressure in the HPO system can cause injector codes to be thrown - IIRC. Perhaps a Tech can confirm or discount this perception of mine (based on memory unfortunately).

BTW - you only have one fuel pump - the HFCM. A new HFCM (pump) does nothing much for the system pressure when you have a weak fuel pressure regulator spring.
