96 grand prix se engine problems
\015 Have a 96 grand prix 3.1 v6 that doesnt run correct. we changed the plugs. we have pulled the plug wire off of the ignition coils while car was running four of the terminals let out spark to the metal bolt nearby so they are working, the last coil we did this with did not spark from either terminal. we switched coils and the coil that didnt work now works and the one that did work now doesnt. we had the ignition module checked and autozone diagnosed it as working. what is the next thing to check on???\015
Your problem may be a faulty (shorted) ignition coil housing assembly (the white plastic cover housing the coils its bolted to the aluminum cover) change that along with the spark plug boots ( the boots are optional but I recommend it) that should get your Grand Prix running smooth.\015\012\015\012Good luck and keep me posted, be glad to help
Check crank sensor.using scanner.it controls coils firing.
