Customer Question
Our 2002 Chevy Silverado...

Our 2002 Chevy Silverado 1500 is having issues with the security light flashing the truck will turn over but shuts off right away.

Mechanic's Assistant: Does the light flash, blink or stay solid? Have you tried to reset the security system?

The light flashes I got it to start and run earlier but went out to start it again and it won't start again

Mechanic's Assistant: Are you fixing your Silverado 1500 yourself? What have you tried so far?

It just happened this morning we don't have the money to take it in so we are going to try to work on it tomorrow. With the wind chill advisory tonight we can't mess with it

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

The gas gauge hasn't been working right for sometime either

This condition is most likely caused by a faulty passlock sensor inside the ignition lock cylinder housing. You can try a relearn procedure by turning the key on and waiting ten minutes. The security light will go off once the relearn procedure is done. Once this happens, the vehicle will start and run. If the problem remains, the ignition lock cylinder (Which includes the passlock sensor for the security system) will need to be replaced.
