my guess is
you fix cars. but?
no fuel pressure gauge
no hand vacuum pump with gauge.
then wonder why you cant test FPR ? 50 is wrong!
buy a new FPR, save on gauges, sure. (and 5 times cheaper than rebuilt ECU)
no full scan data presented, all sensor readings with 02 stuck at 1vdc high,rich, and hot engine and closed loop failing
no data, no way to help you at all, I am sorry.
the FPR must do as post 6 shows, my graph is off a 1996 same as yours, and is correct.
keyon is not 50 PSI , it is not in spec,
so that confuses the H3LL out of the ecu and the injectors over inject hugely
9 PSI more that mine, huge over pressure, huge.
