No battery problem either


My guess is that after it ran out of gas, the key was in the forward position for a while and you unknowingly interrupted the antitheft system. Try to reset it.

RELEARN PROCEDURE:
Turn the key on, with the engine OFF.
Try to start the engine, then release the key to ON, Engine will not start.
Watch the security telltale, after about 10 mins, it will turn OFF.
Turn OFF the ignition, and wait 5 seconds.
Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes. You must turn the ignition OFF for 30 seconds before attempting to start the vehicle after the 3 cycles. Then start the engine .

How do I reset the security system on my 2002 grand am gt. I tried changing the factory radio and now my security system doesn't work


You can try this re-learn procedure, if that doesn't work you will need to bypass the security system. I hope you bought the wire harness adapter for that vehicle. They need 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
  6. The vehicle is now ready to relearn the Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK.
  7. Start the engine (the vehicle has now learned the Sensor Data Code and/or password).

1992 Buick lasbre. Bypassed security module . Turn ignition switch to run waited 15 minutes and car still wouldn't run and security light still on.


why not stated the symptoms.
cranks ok, or not. Dead starter?
wont start at all
or starts for 2 seconds but stalls, or ???????

IS this a STOCK security? system?
if your car has security engine cut out, that needs to be fixed
or in rare cases (bypass/modified/hacked)
on most cars only early systems are hackable. (ask why,)

there are many causes. but #1 is , does it crank ok.?
there are many ways for the security systems to fail (and friends)
the shifter PRNDL switch loves to fail. killing cranking, try cranking in neutral, bingo?
then there is the security system. and the funky keys they use.
if real serious, DIY, get the FSM , and see all the tests there for the
sec. modules.
or alldata.com

many old cars 92 the online documents are bad. poor
the FSM is not poor its dead accurte,
buyone, on ebay used, or near nothing.
on old cars, this IS THE BEST advice.....

Starter wont ignite


Maybe your security system is causing a problem? There are usually ways to see if starter motor will crank the engine, but, if security system is involved, even if we crank it, it probably still won't start.
I can help with testing if you want to try it, just to see if it will crank?

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...


The most common reason for this condition is a faulty ignition switch. It loses contact momentarily while cranking, causing a voltage loss to the security system and starts the 10 minute security timer in the computer. It will not start until the timer runs out. Usually the key has to be left on after a start attempt for the ten minutes. Some cars require 30 minutes. I hope this helps you and please rate this,

Chevy cavalier wont start randomly! makes one click and a humm sound my lights come on the radio comes on but the car just wont start, ive had battery replaced along with the ignition switch, fuel pump,...


Ok then, from your description and the
make/model/year of the car you have there,
it appears you've reset the VATS.

The car's security immobilizer
reader at the key switch
does not recognize the coded
chip in the ignition key any longer.

You can try to put the key
in the ignition, turn to the on position &
wait at least 10 min like that.
(Do not turn off the key switch before
10 minutes as elapsed!)

Once done, the key is re-programmed and
should allow the fuel injectors to work again.
The car would start now if corrected.

In some cases, the VATS (GM'S VEHICLE ANTI THEFT SYSTEM)
will re learn the code this way, and will then
allow the restart, however if this does not work,
then you can simply tow it to any GM vehicle dealer
to have the service department re code it.

There is a permanent solution though.
Adding the PLJX Self learning Bypass module (59.95)
will bypass the PASSLOCK system in your vehicle
for good. See this at www.PASSLOCK2.com

Good luck I hope method 1 does the trick!

Here is the 30 min relearn:

Ignition keys relearn takes about 30 min to do. 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.

Most likely there you have a security system VAT (Vehicle Anti-Theft) module. If you try to bypass this the car will not start. Have a mechanic or yourself get to the main wiring harness to the ignition in the steering column under the dash, unplug it and use another ignition with a key in it to learn the security system code first before trying to start it.
