nice work !
maf ok !
the FPR seems stuck
good, the injectors don't leak
the pump seems great.
pressure, keyon great. 36-43.
40 psi at idle says PFR is DEAD> 30-37 is spec but,,,,, but need to drop from 40 lower. about 6psi lower, its not, the FPR is dead.
and should rize at wide open throttle (vacuum very low, and cause, that too is dead. so double dead FPR.
the PFR is not reacting to vacuum at all., when you start it engine at 19"HG vacuum. the pressure drops, (fuel)
and drops even more.
on this car, id expect.
40 psi key on
35 psi idle
40 wide open throttle (a goal or target, that can not be fully attained, but you see the RISE) (down so fast rpms never get to high)
and if you gun engine and pull a huge vacuum by dropping the throttle fast (25"HG?) then the pressure goes very low, say to 30psi. (closed but not fully there)
i say the FPR is dead.
and acting like above will run very rich, anytime you accelerate and will misfire, heavy. black smoke or hot CAT. effects.
the FPR seems jammed inside, hit it hard to get it to start up (hope) working again, might go a week, who knows.
seems lots of FPR fails of late. old age kicking in,.... many leak... making detection easy.
cheers
and i do hope its the only bad part.
my ugly graph of FPR
this is how it works .
this FPR starts at 36, new in box, keyon. and can drop to 21psi under extreme plenum vacuum conditions,

rap it with back side of screw driver handle, smartly
once fixed car starts running like new car.
i said that wrong, the engine will be way too rich, except at wide open throttle.
because the PFR is stuck there.
