Q: Car won't start due to anti-theft system

asked by on

My car won't start. I think it is because of my GM anti-theft system.

GM’s anti-theft system reads the transmitter in the car key to verify that its the correct key starting the vehicle and will kill the car after it has been running for about 3-5 seconds, but it will still start up. If the car cranks and doesn’t start at all I would look into other parts like fuel and spark, have a mechanic verify your problem and fix it appropriately.
