Answer
Hi Chip, Its quite possable that the starter is bad. Look at the front of the rear valve cover and you should see a connector with a single purple wire. That leads to the starter solinoid. Unplug it and use a voltmeter or 12 volt test light and see if there is power there when the key is turned to start. If so then the starter is bad, If no power then put your foot on the brake and hold the key in the start position while moving the shifter from park to drive. If you get power then the neutral safty switch is out of adjustment. If no power then you will need to trouble shoot the starting and PASSKEY systems further which will require a manual or towing it to the shop. Hope that helps. Bill
