when testing EFI we do the tests and if one thing reads wrong, we do more testing to find out what is cause.
new $400 ECU fails;'
all other tests pass. (ECT, MAF, 180f water temps, scan tools tests, all pass, 02 stuck lean)
all but FPR tests, and not complete, all tests not done. (the full vacuum test NOT DONE)
what if 4x prof. cleaned injectors $88 does not cure the problem, ?
the FPR was $60 at rockauto, and is the cheapest fix on fuel pressure, and most or many are bad know, we know that, seen here vast times. NOW.
the FPR is complex in that it can fail many ways, for sure 22 years old why skip the KEY PART>? (the ECU can not test (DTC) it like on modern cars)
