SECURITY LIGHT COMES ON WHEN DRIVING,EVERYTHING IS OK BUT AFTER MAYBE 4 OR 5 TIMES OF SWITCHING OFF THE ENGINE, NEXT TIME TO TURN KEY TO START ENGINE TURNS BUT FUEL IS SHUT OF. PASS LOCK OPERATES. WE THEN TURN IGNITION ON FOR 12 15 MINUTES BEFORE COMPUTER RESETS AND ENGINE WILL THEN FIRE UP. CAN THIS PART OF THE SECURITY SYSTEM BE BYPASSED?

There is a pretty standard procedure for resetting the security in GM vehicles. This is it.

Perform the re-learning procedure

1. Turn ON the ignition, with the engine OFF.
2. Attempt to start the engine, then release the key to ON (vehicle will not start).
3. Observe the SECURITY light, after approximately 10 minutes the light will turn OFF.
4. Turn OFF the ignition, and wait 10 seconds.
5. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes ( the vehicle
6. is now ready to relearn the Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK).

Start the engine (the vehicle has now learned the Sensor Data Code and/or password).

Your specific vehicle does not actually claim that this works. This is for a few years after your vehicle, but it is worth a try. If it doesn't work, then you may actually have a failure on your hands that needs to be addressed. More info on this site. http://www.diy-gm-security.com/

go to your jag dealer,we cant help you

I can't find a reset for that year of Corvette. It is a Passlock system. So maybe the normal 30 minute procedure will work.

Perform the re-learning procedure

1. Turn ON the ignition, with the engine OFF.
2. Attempt to start the engine, then release the key to ON (vehicle will not start).
3. Observe the SECURITY light, after approximately 11 minutes the light will turn OFF.
4. Turn OFF the ignition, and wait 10 seconds.
5. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes ( the vehicle is now ready to relearn the Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK).

If the engine does not crank, and assuming the battery is charged and the security light is not on, the three most common problems are a faulty starter, neutral safety switch, or key switch.
You would need to know if the starter has battery voltage when the key is in the start position the next time it will not crank.

Next time this happens, check to see if the SECURITY light shows up on the dash. The security that comes on that vehicle can actually kill the motor if its not comminicating properly.

there maybe a few things, how many miles, check the timing belt and timing.

this is a fairly simple fix, you will use a method called 3-10's:
step 1 is to turn key on engine off.
step 2 is turn key to start briefly then let off (maybe a second and then just let off key)
step 3 remain inside vehicle do not touch anything for approx. 10 mins. then on your message board the security will quit blinking .
step 4 at this time you will turn the key off for FIVE mins. and turn back on.
repeat step 1-4 TWO more times, after this time you can turn the key off once again and your done the next time you cycle the key, the fob should be programmed to your computer. good luck

go back the trunk put the key in and turn it resets the system worked on mine found it out googal
i keep take the battire off and didnt work it go off when it get hot but this works the trunk are turn the key resets it strange

The fab key activates the security system in the car, the ignition pass lock may need to be reset to your ignition key's. It Takes about 30 min to do. Try resetting the pass lock to read your ignition keys. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK. Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself. Good luck and hope this helps. The ignition keys has a resistor value for the ignition to read and after a few years the resistance may change and the Pass Lock has a had time reading it's value so you have to reset the pass lock to read the keys again.

You have a Pass lock problem. There are 3 wires from the Ignition switch that reads the ignition key, if you have lot's of other keys on your key chain. That puts extra stress on the ignition lock switch, which in turns wear out the wires in the lock that reads the key.
The dealer will cost over $500.00 to replace the lock and key's to match. I got a good friend at a lock smith to over ride the system by running a diode across the 3 wires, but now i have no pass lock.
Try this, it might help if the wires are ok, it's to reset the pass lock that the dealer will try and still charge you hundred of dollars since they want to change the lock and key's for you.
Good luck and hope this helps: The relearn process is pretty simple and will take 30 minutes, if it'll work for you at all since your problem doesn't sound like a computer issue.

The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to Crank.

Important:
Turn the Ignition Switch OFF.
The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password.
7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles.
Without a scan tool you may have momentary starter interruptions while history clears itself.
