if the vehicle starts then stops and the anti-theft light is flahing you may need to re-set the pass-key system to do this you will need to atempt to start the vehicle and when it stalls leave the key in that position and watch the anti-theft light. it should flash on and off for about 5 to 10 minutes. when it stops flahing turn the ignition to off then try to restart your vehicle

Your car is equipped with a system called PASSKEY standard on all GM cars and light trucks, try the following procedure to reset the system, the battery being dead will trigger the system.

1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the passlock system to recognize your key.

SOURCE: 96' sunfire changed engines 2.2 starts dies theft light comes on

The problem is the new PCM you installed does not have the correct VIN number of your car.
You may be able to relearn the VIN using the preceedure below, however, there is no gaurentee it will work. You may have to have a dealer reset the VIN for you by way of a scan tool.

1) Instert key into ignition and rotate to run position (do not try to start engine)
2) Leave the key in the run position for 10 minutes until security light stops flashing.
3) Turn ignition key to off position for 10 seconds ( no more, no less)
4) Turn ignition to run position again for 10 minutes until security light stops flashing and repeat step 3 and 4 for (1) more cycle.

The process is a security verification step for the VTD system. ( Vehicle Theft Deterent)

Give it a try, let me know.
Regards,

SOURCE: How to remove or bypass the factory installed anti theft vehicle immobilizer.

in the 1996 sunfire GM uses an anti theft lock system. It can be triggered by all sorts of things. In order to relinquish this you must have a key to turn the ignition. These are not coded just plain cut keys. Once you attain this you put the key in and turn the ignition to the ACC position and wait ten minutes (theft lock light will turn off), turn off and take key out. You MUST do this 3 times and then the theft lock will be disarmed.

I have a 1999 sunfire gt and it starts runs for a second and dies,my anti theft light on my dash is not blinking it just stays on,does anybody know a way to bypass the anti theft so that my car will r


Yes, unfortunately this is very common on GM vehicles. Go to this link for everything you need. Rule of thumb is this. If the light is flashing, the problem will be In the ignition or the smart transponder key. If the light is solid, the problem is in the TDM (theft deterrent module). This is the main computer for the theft system. There is a full bypass method on this link listed under PERMANENT FIX. This is what you will need. It will bypass every aspect of the system 100%.

no but what you have bad is your remote start brain box that is triggering the anti theft. i suggest taking to a auto electronic place for servicing or stop using remote start.

How do you reset the theft system (for the car, not the radio) on a 1996 pontiac sunfire se. the battery went dead and the car has been sitting for a month now. the car will not start with the key. it will...


Your vehicle is equipped with the Passlock theft-deterrent system.
Passlock is a passive theft-deterrent systemT. he system is armed once the keyi s removed from the ignition. Passlock enables fuel if the ignition lock cylinderi s turned with a valid key. If a correct key is not used, fuel is disabled.

During normal operation, the THEFT SYSTEM light will go off after the engine is started. Ln the unlikely event that the engine stalls and the THEFT SYSTEM light flashes, wait until the light stopsf lashing before trying to restart the engine. Remember to release thkee y from the START position as soon as the engine starts. If after several tries the vehicle still does not start, the vehicle may need service. At this time, you may also want to check the fuses. See your Pontiac dealer for service.

If the THEFT SYSTEM light comes on while the engine is running, a problem has been detected and the system may need service. See your dealer for service. In an emergency, call the Pontiac Roadside Assistance Program at 1 -800-ROADSIDE or 1-800-762-3743.

This ans other details can find it in this link for 1996 Pontiac Sunfire - Owners Manual.

I hope helps (remember to rate and comment this).

Securetylightison and wont start have fuel/spark trys to run then stops cycle key then start then shuts off admidiatly


your car was build with an anti-theft devise from GM, inside the ignition key is a micro-chip, when you insert the key in the ignition cylinder, the sensor inside the cylinder will measure the resistance of that micro-chip inside the key, if there is a match the engine will start, if no match the computer will think someone is trying to steal your car & shut it off.
try using another ignition key (spare key) if this doesn't work most likely the tiny wire inside the ignition cylinder is broken therefore the ignition cylinder will need to be replaced.
