Question about 2008 Chevrolet Cobalt
Everything works but the car won't start and the anti theft symbol comes up.
Put the key in the ignition and turn to run position (do not crank over engine) and let it set for about 10 minutes, repeat up to 3 times, if this still doesn't let you start you will need the dealer to reprogram the systems control module.

You can start it by putting into program mode...try to start, then turn it to off..,,then turn it to on (not start)..leave it on for 15 min...turn it to off for 2 min..and start..
This will reset the signal from the bcm to the pcm of the car.
you most like ly have a problem in the start switch key reader...It has to be replaced as a unit
Or it could be your bcm or pcm...very very expensive... try this first... If it does not work off to the dealership..don't even try to give this to a garage to fix. Gm has the software to reflash your computer.

On a 2003 Chevy Maibu the theft system light comes on and blinks when the system is triggered. The car will not start and the fuel pump cuts out. You must turn key to on and have all doors closed. Keep the key to on for 10 mins til theft light turns solid and then disappears. Then turn key to start and it should fire up.
