I drove my 2003 Monte Carlo SS yesterday with no problem. However, I do have a security light on and a low engine oil light. Something is killing my battery over a couple of days. This was going on before I had an aftermarket sound system installed. Is there a way to disable the Passlock security system. Car seems to not be getting fuel. But if I keep my foot on the gas, it on. As soon as I take it off, it dies.
