Question about 2001 Pontiac Grand Am SE

1 Answer

2001 pontiac grand am 3.4 V-6 Was running fine, stopped. Tapped on igniton coils, started again. Could tap on them and it would hesitate or stop. All coils with good primary and secondary resistance. All fuses with 0.0 ohms. 12.0v supply to ingition module and ground is good. Crankshaft sensor with 200+ millivolt signal. Had excellent spark from coils, now none; have replace ignition module twice! Turns over great, but NO Spark at coil towers or from module. Noticed a 'static' shock when getting out of car last few times. Could it be sending the spark to the chassis? HELP! Thanks!

Well I can tell you no matter what your gauge says on the groundwires to the system..... you've got a bad ground or a hot touching ground somewhere and I think that you should recheck your steps. Not all books are always correct in their schematics when it comes to your individual car especially if your not the first owner and don't have a complete history of work performed prior to you owning it. ie. stereo, drive lights, electrical modifications or repairs etc. etc. I would start with the body ground myself. clean its application area and make sure you are getting a true metal to metal contact. As with all your connections.
