1988 cav. z24 stalling

we recently aquired this car. we knew when we got it that it stalled
but we thought wwe could fix it. several months and parts later it
still stalls.

no rhyme or reason. Ran great first few times i drove it. Would
stall only at idle or full stop. Would start right back. then the
battery got low. Replaced it still wouldn’t run. Now it won’t stay
running.

Replaced idle speed module, ign. coils, spark plugs, wires, fuel reg.,


Any thoughts?

First of all when it stalls, do you have spark?, fuel? Try spraying carb
cleaner into the intake see if it keeps running.

Yes we have spark and fuel. Sometimes it will run for as much as ten
minutes, and in gear. then stalls out and will not restart.

If you have injector pulse/fuel getting into the cylinders and spark is it
has to run, something is missing how do you know the injectors are pulsing,
you need a noid lite or some way to cofirm injector pulse and fuel delivery
to the rail.

You would think so but it doesn’t. We are getting a code scanner
tomorrow. Maybe that will tell me what is wrong with it.

I know it it getting fuel you can smell it. But it isn’t flooded.
What ever is wrong with it has a 30 year chevy vet and many other
mechanics stumped. I know it will be something stupid in the end. I
was hopeing maybe someone with a similar problem would surface.

I will let you when I find maybe it will help someone else.

I have an '88 Z-24 and it would mysteriously die, would then re-start
but if you put any throttle ressure on it at all, even in neutral, it
would die...to make a long story short, I had it towed to a shop and
putting a new ecm on it was what finally fixed the problem (no codes due
to this).
Another thing they are notorious for is the crankshaft position sensor
connection becoming fouled with oil, hence neither the injectors nor
plugs will fire since the computer doesn't "know" the engine is being
cranked since there's no pulses from the crank (the tach won't move
during cranking when this is the case, which is a clue) but I don't
think this is the problem in your case now but it's just kind of a FYI.
Let me know what the problem finally was (either post or email me).

These 2.8 multiports also have a separate, cold-start injector.
This is an additional fuel injector in the intake manifold that
improves cold starting by spraying additional fuel into the intake
manifold during cranking.
It is not ECM controlled.
It is activated by the cranking system and is controlled by a timing
mechanism.
It does not activate if the engine temp is above 68° F.
But the reason I'm mentioning it is that when it does activate it
would produce the gasoline smell you mentioned even if the injectors
aren't pulsing.
