sorry i missed all those facts (data old and new
Ok i see it now.
so all tests pass car runs like new, LOL
and only the leak down test fails.
my guess is its not injectors,
leaks down how fast from what to what PSI in what seconds.?
do not use the old FPR, its no good, bad to consider using it at all.
if you use the old FPR, all reading will be bad or random, as expected from any diapharm of any kind cracked. and valve badly worn at the same time.
ok the old FPR fails vac leak down
and the cracked diaphragm is now leaking fuel as all do as is the damage progresses fast sure it does and will.
we need to move past all old FPR.
you are down to just 2 things, injectors or pump (and hose)
or lazy way first?
parked key on 10 times
then wait say 30minutes (crossing fingers for intake valves that seal 100% , that can happen with hand lapped valves on new heads)
look in all 4 spark holes for the flood on top of pistons
but doing the test 1 cylinder at a time intake valve open any amount makes for 1 minute test. results.
cheers
the leak down tests fails with fpr hose (fuel return) pinched right? so that means fpr not it , injectors are bad the check valves leaks or the top pump hose leaks or the camps on it are loose.
if you test the injectors to see if they leak, (not easy) then they are not leaking, or get them clean at witchunter.com.
testing MPI injectors on a car is not easy. (bore scope? to spark hole, wet tip of spark plugs) pools of gas on top the piston crowns. test each cylinder 1 by 1,. with its intake valve open, yah , that works wonders to see the river of fuel to piston top..
if the injectors pass ,. the the check valve leaks, if it does, ignore it.
in fact it will get better in time as used. the brand you got is OK !
