Hi, the most likely cause is the range switch on the transmission, but it could also be the relay or the ignition switch. You can diagnose by interrogating the socket under the starter relay using a 12 volt test light. The starter relay is probably in the box under the hood by the air filter box. Just pull the relay out, connect your test light clip to ground, and probe the socket while someone holds the key to start. If the ignition switch is good, there will be 2 hot terminals in the relay socket. Next, move the test light clip to battery positive and probe the socket again. Assuming the transmission is in park, there should be one terminal that lights the test light brightly and one that lights it dimly. If there is no bright light, the range switch is bad. If there is no dim light, the wire from the relay to the starter is bad. Finally, if all of the tests are good, the relay is bad. Please let me know the results of your tests for repair advice.
