Theft car system

Started the car and a warning light came on 'theft car system, car may not restart.' we started it and engine worked, and turned it off. Is there something we need to do so this does not happen again?

Dear Hun~ It all has to do with the Vats system in your car. You can bypass it or get a new key or you might need a new ignition cylinder.

99 explorer alarm disables. Motor dies


Anti-theft system can keep vehicle from starting , Alarm is for vehicle content theft , open door without key alarm sounds (horns) ! PATS - passive anti theft system PATS enables and disables the engine from starting ,it will not cause the engine to die ! You have some other kind of problem ! If the vehicle engine doesn't turn over an red light on top of dash flashes fast ,then you have anti-theft system problem !
PATS differs from the perimeter anti-theft system in that PATS enables and disables the engine from starting. If equipped, the perimeter anti-theft system protects the perimeter of the vehicle (doors, hood and trunk) and sounds an alarm.

My 1998 Ford Ranger will not crank or start is it the factory alarm or anti theft alarm? How could I fix it myself


Is the security light flashing while trying to start the vehicle ?
The theft warning system provides the vehicle with protection from unauthorized entry into the passenger compartment and engine compartment (hood opening). It also protects against engine starting through ignition keylock cylinder tampering. If triggered, the system provides both audio and visual alarm signals and disables the starter circuit.
Sorry but you will have to take it to the dealer if it's the anti-theft system

Engine turns over but will not start. warning light is on, car with a key on it


Sounds like the anti theft system/ immobilizer. Try cleaning out the ignition tumbler by squirting carb or engine or brake or electric cleaner into the key hole.

To clarify, the anti-theft system will not kill the engine once it is running. The check gauges warning would be expected if the key switch was on and the engine was not running. No oil pressure was the most likely cause for the warning light.
The anti-theft would prevent the engine from cranking, but since the engine died I would expect to find something mechanical or electrical with the engine. Especially since you just had it replaced.
I would have the car towed to another shop and get it checked out. You may need documentation for a future lawsuit against the previous shop. If you work on it yourself its your word against theirs.
I hope you have a written warranty from the shop that installed the engine.

You need to reset the theft system. To do this, try to start it. It should start and die. Then after it dies and the theft light is flashing, leave the key on for 10 minutes. After 10 min, the theft light should go out. After the theft light goes out, turn off the key. Count to 5, then restart it. Then it should work.

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).

The theft system is set on my 1997 chevy cavalier help


If it is a pass lock system just turn the key to the on position, but do not start the engine and wait 10 minutes until the light stops flashing. Then turn it off and restart it. It should go away. If the light is not flashing in the first place then I don't know.
