Your vehicle is equipped with the Passlock®
theft-deterrent system.
Passlock®
is a passive theft-deterrent system. Passlock®
enables fuel if the ignition lock cylinder is turned with
a valid key. If a correct key is not used or the ignition
lock cylinder is tampered with, fuel is disabled
During normal operation, the security light will go off
approximately three seconds after the key is turned to
RUN following an engine start.
If the engine stalls and the security light flashes, wait
until the light stops flashing before trying to restart
the engine. Remember to release the key from START
as soon as the engine starts.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the
engine off. However, your Passlock®system is not working properly and must be serviced by yourdealer.

but the clutch switch is failing and can be jumpered easy, your paper clip. some switches have adjustment or are just fell loose.

Do you know how complex the electronics are on that vehicle ? What happens when you turn the key to start position ?
Circuit Description
Moving the ignition switch to the start position applies ignition voltage to the switch side of the STARTER relay. The powertrain control module (PCM) receives a serial data message that crank has been requested from the body control module (BCM). The PCM then verifies that the transmission is in the Park or Neutral position and that theft is not active and grounds the control circuit of the STARTER relay. Battery voltage will then flow through the switch side of the STARTER relay to the S terminal of the starter solenoid, cranking the engine. Ground for the starter is supplied through the engine block.


Hook up a scan tool an check for codes . All system scan ,all control modules on the vehicle .

Passlock™ System
The theft deterrent system has been incorporated into the body control module (BCM). The theft deterrent system is provided in order to prevent the vehicle operation if the correct key is not used in order to start the vehicle. The ignition key allows the lock cylinder to rotate. The cylinder rotation produces an analog voltage code in the Passlock™ sensor. This voltage code is received by the BCM. The BCM compares the voltage code to the previously learned voltage code. If the codes match, a serial data message is sent from the BCM to the powertrain control module (PCM). The message enables the fuel injector operation.
The design of the Passlock™ system is to prevent vehicle theft by disabling the engine unless the ignition lock cylinder rotates properly by engaging the correct ignition key. The system is similar in concept to the Passkey system. However, the Passlock™ system eliminates the need for any key mounted components. The components of the Passlock™ system are as follows:
• The ignition lock cylinder
• The ignition switch
• The Passlock™ sensor
• The BCM
• The security indicator
• The PCM


Passlock system does not keep the starter from working . Try putting the vehicle gear selector in neutral an see if the starter works then.

No Start Due to Failed Passlock Sensor : Pontiac Grand Am ...

if its not your passlock system then you should get a fuel pump pressure test done on the vehicle

If it doesn't even click and the battery is Ok it could be a fusible link.

The security system is activated. It kills the injector pulse ( signal) and on some modles the starter. You will need to try to relearn the system. First try to start the car, leave the key in the run position for 10 minutes. Cycle the key off, then cycle it to the run position again for 10 more minutes. Cycle it off again, then back to run for another 10 min. after the last cycle turn it off then try to start the car. It is a 30 minute relearn. If this does not work you will need a repair shop to replace the passlock sensor. Good Luck

Try to reset the passlock first. It's free and won't cost you anything to try. My car did the exact same thing and I didn't see the security light on..I'm not even sure it was on but, reseting the passlock fixed the problem. Look at dvj2a's solution.

Yes it is the starter if you have had the battery tested and you are sure that the battery cables are in good shape, no white corrision on posts/terminals.

set it on fire, thats what i did

It was the security Passlock system on my car as well. I did't notice that the security light had come on the first time. Look up Passlock in the owners manual.

1. You can reset it yourself for free by turning the key to accessory position
2. Leave for ten minutes on accessory mode.
3. Turn car off completely
4. Try to restart.

This fixed my problem on my own after I paid to have it fixed and it happened again the next day.
