1996 Pontiac Grand Prix 6 cyl Automatic 78000 miles
Last week my car died and then when I went to start the car all the dashboard lights would flicker and make the sound that the signal makes. The mechanic found a loose wire and fixed it, they determined that the starter, alternator, ignition switch, battery, cables were all okay. The radiator was replaced last year. I drove the car for five days and the same thing happened again. I drive prety local and do not take the car on any long trips. Both times it took like 30 minutes to jump. And the second time it made the same sounds, the lights flickered and the engine would not turn over. The mechanic is unable to find what is wrong.
Scan for B codes as a first step, then check the connectors at the back of the instrument cluster. Check for loose pins on the cluster, and bent or pushed out pins on the connectors. GM put out a tech bulletin about their connectors, ALL of them! So start checkin!
