I'm sorry I no longer have the snap on fuel,pressure rig in my possession. So running test are not available.
when testing it I removed it from the rail and bench tested the FPR and it held vacume no leak down?
I'm still not sure what your saying, you say my fuel pressure is to high at 40psi when 36 to 43 is spec?
Also one there is no vacume applied to the FPR while running its natural to see a higher reading?
Motor has good vacume reading 19-21 in/hg
One another note i checked for ground at the ECU on the sensor ground pin to verify ECU is getting a proper ground , checked out good. Also checked the ect reading at the sensor and at the ECU and checked out good.
I'm leaning back to having an injector problem even know there is no miss. Going to remove them and clean them and bench test them.
