My 97 Bonneville 3.8l just 3 days ago wouldn't start because of 0-10 degree weather. It did crank but acted like it was back firing 2-3 times and then threw check engine light and won't crank now, the battery has 12 volts, but won't even attempt to turn over engine. i rented a Autoscanner from Autozone and it says there are no codes stored. any help would be helpful.
check engine light with no crank on 1997 Pontiac Bonneville
Any time the car won't crank and the key is on, the Check Engine Light is on. May be have a tow truck give you a jump to see if your car will turn over. Not sure why it back fired, but first get it to turn over correctly and then go from there.
thanks for the reply dandd... i've tried jump starting, it seems electrical system is "locked out from turning motor over"??? i'm ckecking to make sure i've got 12v at starter, but any other ideas would help. thanks
