ever auto store on earth has fuel pressure gauge, even Harbor Fright(pun)
no shop working fuel injection can make progress lacking this first gauge.
I bet the FPR is dead. that is whaT i BET, BUT I CAN BE WRONG WITH pressure test data, then guessing ends.
data = cures. = evidence.
The tests are there 5?
keyon (bet you if this test is done first it fails, yes,shunt test is next to see if pump is bad next) key on is the high reading so is first.
idle (lower by 5psi)
wot (rises to near keyon)
shut test proves pump good or bad in 5 minutes work 55psi?
leakdown test is not too important but will find leaking injectors , a far worse horror.
