Unfortunately only a Mod
could make the move but, not matter, as I said "we found you!"
Not sure what screen you're looking for, or even what it is you took apart looking for it...
Sounds like you are getting fuel into the filter housing OK, now if it IS fuel delivery, it's between there and the injectors maybe. Being it's an all-of-a-sudden
kind of thing hopefully something's just failed....
The two sensors that control that is the ICP and the IPR (they're expensive so you don't want to just go "try" one
) BUT you get FREE
test by unplugging the ICP to allow the PCM to set a default reading and see if it helps (doesn't sound like it either but again it's free)
From there it's maybe the electrical side of the injection system controlled by the IDM to the injectors themselves through the UVCH plug. If the UVCH was the problem it would be running very ruff because you'd be dropping cylinders and it doesn't sound like you are.
THATS where the scan's gonna help
It will get a code to point you to there it
thinks the problem is!
