Our trusty car decided not to work yesterday. My wife was out with my son, and when they got to the car to go home, it wouldn't start. I drove over to take a look, and everything was working (starter turned, fuel geting to fuel rail etc.) but it wouldn't fire up. I checked all fuses related to fuel and ignition and everything checked out. I disconnected the battery to see if that would reset something, and it almost started, but no luck. Had a mechanic pick it up to look at it and when I spoke to him that afternoon, he said it started right up. could this be a passlock issue, and if it is how do I fix it?

Bueller?

If this was a pass lock issue you would need the proper tools to diagnose what is actualy the problem.

When it fails to start agian try the security relearn.
1) Attempt to start the car by turning the key to the Start/Run Position.
2) Observe that the vehicle fails to start and that the security light is illuminated.
3) Release key to the 'ON/Accessory' Position. (DO NOT turn key to the 'off' position.)
4) Allow the vehicle to sit with the key in the 'ON/Accessory' Position for no less than 11 minutes.
5) Turn key to off position and allow the vehicle to remain in the 'OFF' position for no less than 30 seconds.
6) Repeat #1 - #5 for 3 cycles.
7) On 4th attempt, car should start.

NOTE : Since this is a fairly long procedure, I would limit all electrical sources, such as disconnecting headlights, to prevent discharge of battery.

NOTE 2 : It is SAFE to wait LONGER than the allotted time, but it is not safe to wait less time. I.e. 12 minutes instead of 11 minutes should be safe; however, waiting 10 minutes instead of 11 minutes is not safe.

Properly executed, this procedure should take approximately 35 minutes to complete.


But its usualy the lock cylinder or ignition switch, could even be both.
Also if thier are many things hanging from the key chain(s) this will also cause starting issues.

Thanks for the response. The problem hasn't come back yet, but when it does I will try your suggestion.
