Hello I have a problem with my Pontiac 2002 Trans Am - Collector Edition. It does not want any more to start, there is the indicator SECURTITY which east lights, and since average making it function. Can you please say to me what that can come. With my thanks, Cordially Pascal GARZONI

Check the battery voltage with a multimeter. If the battery can't deliver a full 12 volts, the starter solenoid won't even activate. It may be that a cell went dead, causing a direct short inside the battery. Replace the battery if your battery is older than 3 years, or take it to an auto parts store to have it tested. The security light on is an issue many people have when the battery is low and the car won't start.

It is also possible that the security chip on the ignition key is worn. If it isn't making contact properly, the computer won't 'read' the resistor, and won't start. You will need to replace the key to see if this fixes the problem.

I’m happy to help further over the phone at https://www.6ya.com/expert/jeremy_69f3cc28d95bf514
