car attempting to start while running

Check the bypass, if they cut the yellow wire, try using a different bypass (INT-SL+). One more thing this car, the resistance is in the switch,if the security light flashes, because is loosing the resistance value at the switch,the car will never start if this light is flashing, so what I think is the ignition switch is going bad,and one day the car is going to die while she is driving, there are no recalls from Chevrolet, but I have experience this problem before.
