Your engine will not run properly below 32 psi. Really want to see it up there in the 34-36 psi range, and pressure should hold with very little drop over the periods of 15, 30 and 60 seconds after you turn off the key.

Thanks for validating. This has really been a pain to get figured out. Almost at a point that I just replace it & hope for the best.Originally Posted by EuropeanAM

Does it hold at whatever pressure you're getting? Separate, KNOWN ACCURATE gauge tried?

It holds steady at 25 psi when running. Does drop a little after shutdown after a few seconds. But only 2 or 3 psi. Gauge is accurate.

Odds of this being an ECU issue?

ECU just turns pump on doesnt regulate psi , needs 34-36 lbs ^^^^^ post number 61...... odds 0

Ok, didn't know if the fuel pump drivers in the ECU would have anything to do with it.
Thanks!
