Did you go out today only to find out your car wouldn't even try to crank over? Something similar to this?
Some customers may comment that the vehicle will not start intermittently. This comment is referred to as "no crank, no start with complete power."
Additional customer comments may be as follows:
• A clicking noise may be noticed when the key is first turned to the START position, but no noise is heard after the initial start attempt.
• The "Security" light may flash immediately after trying to start the vehicle along with the message "Service Vehicle" in the Driver Information Center.
• The vehicle may not start for at least 10 minutes after the first attempt to start the vehicle. Diagnostic trouble codes (DTCs) B2960 and/or B3033 may be set in history in the body control module (BCM).
When the key is rotated from the RUN to the START position there is a voltage signal sent to the BCM that goes through the PASSLOCK™ resistor in the ignition switch. An inconsistent contact inside the ignition switch between the printed circuit board and the contact finger may cause a no start condition.
Replace the ignition switch. Refer to Ignition and Start Switch Replacement in SI.
Important: The 30-Minute Learn Procedure must be performed after the ignition switch has been replaced. Refer to Programming Theft Deterrent System Components in SI.
Short answer: your ignition switch is bad. You can get a new one from Saturn/Chevy for about $30.
