Why does my computer reset upon almost all startups? Just put in a new starter and now if I start the car after it's been sitting for a couple hours or more it resets the PCM and the guages reset as well as the tripometer.
Any ideas?

Re: Why does my computer reset upon almost all startups? I dont know if its "resetting " your computer. It just spikes the gauges and resets the trip meter. My 99 TA used to do it only when it was very cold out. There is a TSB out on it. Last month it started doing it everytime I started the car. A weak battery will casue this problem. I changed the battery and problem is gone. Look there.

Re: Why does my computer reset upon almost all startups? There is a service bulletin about the gauges resetting themselfs, I believe the number is 990849009. Two things that I know of that can cause this problem are, a weak battery or a bad gauge cluster. Check with you dealer and see if it's covered under warranty, good luck.

Re: Why does my computer reset upon almost all startups? I had exact problem. It was the battery on its way out the door. Apparently the connectors had corroded, and I also found my battery mount had been completely eaten through by acid, and I need to get the bolt drilled out. Looks like my new one is doing it now too..

Re: Why does my computer reset upon almost all startups? I had this occur on my 99 last year. Dealer replaced my entire front console. They had to talk with Pontiac and Pontiac knew of the issue and sent a replacement console.
When I started the car my trip would reset and my gauges would spike.
Mine was under warranty.
Best of luck
