This sounds like a simple answer, but it may be the key. I have a a '97 Aurora and the key stopped working. It wouldn't crank or anything. I used the other key I had, and it started right up. I then took the "non-working" key and cleaned it with rubbing alcohol a little (with a paper towel... NOT directly in the alcohol), and it then worked. On and off this would happen over the winter. All summer it's been fine. -Lori
Check your ingnition cylinder ...
maybe ignition modual
Check the ignition control module.
might be starter relay, or the crank circuitry from the switch or to the starter from the relay. I would trace back from the starter to the starter relay back through the neutral safety switch to the ignition switch.
I would suspect the ignition switch has failed. This is the ignition switch not the tumbler assembly that you insert the key in.
The neutral safety switch is bad, the ignition does not recognize it is in park. Your ignition switch may be bad.
The ignition switch in my wife's 98 accord went bad a few month ago. The car would randomly shut off while driving, then it wouldn't start back up for another 15 mins or so. It would crank, but not start. It's an automatic. To diagnose that the ignition switch was bad, I had the car in gear (D), turned the key to the "start" position. The car is not going to start until I put it into neutral or park. Then I'd slip the leaver into neutral, the motor would crank and start up, then I'd slip the leaver back into Drive (so the starter motor would stop).
Sure as long as it is still in working order.
check the ignition switch , it might be bad and may need to be replaced.
I am working on changing my 93 Explorer ignition switch now. As soon as I figure it out I will let you know. :-) Still working on it.
Posible relay problem
Are you talking about the electronic ignition module or the ignition switch? The ignition module sits in the engine compartment and is part of the ignition system (coil, spark plugs, etc). The answer is no if this about what you're referring. The answer for the ignition switch will depend on the vehicle you have. Some, like late model Fords, you don't. Push in the retaining pin and the ignition switch comes right out (you still need a key though). Others you need to take off the steering wheel to replace the switch.
