Engine Stalls

[fixkick]

ok ,knife edge stalls, right foot, cannot save it.
and is not the maf the tests are ok

id say spark ends, is the cause.
ECU fuses bad, rusty or with internal cracks,
if the ECU looses power, even the CEL goes dead,
as the engine stalls ,
the tacho will go dead,from say 800 to 0rpm
then the cEL must come on, does it, if not, the ECU just lost power
if the pump lost power the RPMs fall slower, and right foot can help here,
the knife edge stalls are: (LIKE A CLIFF FALL)
lost power to ECU, the scan tool goes dead at the same time, connected at the time it stalls
if the distributor fails. if the scan tool is connected, and CEL comes on, at stall, guess what, you see CKP, CMP or spark lost DtC ERRORS.
LET IT STALL ,DO NOT TURN OFF THE KEY, SEE THE ECU TELL YOU WHY IT STALLED. (all but fuel pressure can be reported, let it)

BELOW 200 RPM The ecu thinks engine is dead, then turn on the CEL, NOW ,AND FOR SURE 0 RPM
You can push start this car, keyon ,CEL on
or graVITY START, ON A hill, dumping clutch in 2nd ,gear, key on ,CEL on;

you are losing spark, (random)
are all engine grounds good? under the hood, there are many, and any found loose are bad news for EFI.

owning a scan tool makes diagnosis more easy
ecu lost comms
ECU shows errors, at stall.
ECU CEL DEAD AT END OF STALL.
P03XX Errors.

ours has FI fuse, IG-coil fuse and the dome fuse for ecu memory
not sure on 99. names of fuse.
fuses can have hair line cracks, and are a horror if true.
