1994 Pontiac Grand Am Car will not start

Watch the headlamps with the key in the start position. If the lites stay bright and no reaction, it sounds like an open circuit to the starter. My first thought was the neutral switch. Could be other issues? You could use a remote starter button at the starter solenoid, the leads might be long enough to get you out from under the vehicle, just to see if the starter will crank, you don't have to use the key. Make sure the tranny is in park or neutral and a functional e-brake is set.

Where applicable, I didn't look at your security system?
