2004 Saturn Ion 4 cyl Front Wheel Drive Automatic

My wife's Ion, usually on cold mornings, occasionally will not start. It usally turns over a once or twice before not turing over at all. The battery is fairly new and was load tested (checked fine). Lights do not dim during starting attempt. Usually when I give it 5-10 minutes and retry, it starts up. When it first fires up, after not starting initially, it will die if you do not give it gas. It only does this after it fails to start. The car has 100,000 miles on it. Thanks for your help in advance.

Try this info, Some customers may comment that their vehicle will not start. 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 car 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 BCM.

Cause
When the key is rotated from RUN to START there is a voltage signal sent to the BCM that goes through the PASSLOCK resistor in the ignition switch. This voltage signal may have an early ignition switch bounce (when going from RUN to START) that the BCM interprets as a failure in the PASSLOCK system and disables the starting circuit. Replace the ignition switch. Post back with any other questions.
