While driving engine shut off momentarily, ran good for while then it quit. Restarded drove about 1 mile and surged and then quit. did this a couple more times finally it would not start. Checked fuel pressure by loosening fuel line there was good spray. rotor and cap looked good. gat gas on the tank. It will attempt to start just that. Next mornig started right away. It was at fast idle but as soon as i gave it some gas it will quit. It will start imidiatley. Any clues?

 

Maybe the ignition module located inside the distributor under the rotor. Heats kills them since it's an electrical part. They can be tested at local auto parts store, new one like $35. Make sure you use the dielectric grease on the plate - if tests good, grab a $1 pack of dielectric grease to regrease it before install. New unit hould come with grease.

 

TY the check engine light have been on for a while I extracted the code 43 which is related to the ESC I will check it.

 

A leaking injector can cause warm starting problems as it will flood the engine when sitting. If it sits for a longer time, the fuel seeps past the rings and it will start normally.

 

Well changed ecm temp sensor knock sensor fuel filter, fuel press good spark good. I am going to try replacing PROM mine is ARPM the closest one i found was ATFM . Anybody knows if this will work? 1990 3.1 camaro auto. No cruise control or any other power accessories. Put new plugs, all look like burning rich except for #6. By the way timing was checked twice. Any Ideas?

 

Did you remove and have that ignition module tested? Most parts stores will test for free, but I've never tested them, I just replace them.

 

I replaced the ignition module and no fix.

 

ohm out your injectors? whats the actual fuel pressure? a spray can happen at 10 psi.
