1989 Pontiac Formula 350 that won't start. New plugs, fuel pump, ECM, injectors are good, has spark. Out of options!

Was the distrubutor ever removed? If so was it put back correctly? Have you tried to start it with anything else like starting fluid or WD40 ?

Thoughts:

. Test all under hood and under dash fuses with a test light or multimeter.

. Replace the Ignition Control Module--you may have spark but it may not be firing when the ECM directs. These are problematic components.

. Check each cylinder's compression, if the problem persists.

Anyone that has this problem, check the harness behind the distributor. Mine was open.

Thanks to you two that posted! I thank you very much!

irocbradley, try the same procedure as recommended above:

. Test all under hood and under dash fuses with a test light or multimeter.

. Replace the Ignition Control Module--you may have spark but it may not be firing when the ECM directs. These are problematic components.

. Check each cylinder's compression, if the problem persists.
