I have a 92 Regal. Yesterday it would not start at all. I turned the key to run and there was no radio, no clock, no gauges. The headlights didn't even have power. I jumped it off another car for 2 minutes and it started right up like there was no problem. The charging system is working just fine and I did not leave any interior lights on, nor was the glovebox light on. This was my moms car prior to me and a Buick Dealership replaced the ECM saying this was the culprit. My aunt has the same car and she had the same problems and a dealership preformed the same fix. What I dont understand is how the car was completely dead, even the headlights, yet it took only 2 minutes for the battery to be charged to crank it over. The car cranked over with no problem, and this was after removing the jumper cables. Anybody have this same problem and what was the fix?

Those lousy side-terminal batteries have such small contact area that when a little part gets some corrosion, not enough current is available to energize the car. Take your battery cables apart and clean them with the proper wire brush terminal cleaner. If the bolt has excessive corrosion on the threads see if the battery is leaking acid onto the threads.

Switch the battery first.
The dealerships love to tell you it'ds the ECM charge you $ 350 and really it's the battery, cable or corrosion.
The ECM has NOTHING TO DO WITH headlights, radio.
The condition you are describing is a no volts condition. Please check the ground cable connection to the chassis also.

I checked the battery and terminals for corrosion over the weekend. I could not find any. All the battery terminals were tight and corrosion free. The tops and side of the battery were clean. The battery was purchased in May of 2005. I check all the relays and connections on ther underhood relay center and they are all in good shape. The car has not died or acted up since then. The only thing left for me to do is perform a lad test on the battery. I am still in the dark as to why it acted up. We have had some pretty cold mornings up here and the car has been starting normally.
