For the owners manual try, gmownercenter.yahoo.com
You have to register your vehicle, year--make--model all that good stuff. It's free. Follow the links.

As far as the computer, try a relearn procedure.

If the security/theft lite is on when it stalls, leave the key on and wait for the lite to go out, may take about ten minutes, then cycle the key off and try to restart.

That was the reason why I replaced the computer. But right now I don,t know if replacing the computer fixed that problem or not because it won't stay running.

When we took the car to the auto parts store last week they tried to check it with their computer & said that they couldn't get any reading so the computer in my car must need replaced, I did that no it won't run. Other than that I don't know have only had the car for a couple of weeks.

Did you check the data link connector, before replacing anything? Pin 16 has to have voltage or you can't communicate with computer.

The new computer needs to be programmed. The dealership may have to do it.
