Answer 1

You will have to get the code(s) checked in the PCM and BCM to see what has been caught and is acting up. Most of the problems associated with this car's theft system were related to a voltage drop inside the ignition switch. The only fix is to replace the ignition switch in the dash. If you have aftermarket alarms or auto start devices installed, that can also cause a ton of grief.
