SOURCE: Anti-theft

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

Try this first, it 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. Good luck and hope this helps, keep me posted, be glad to help

Okay two weeks ago I was inquiring about a 1996 pontiac grand-am, this car is in overall excellent condition from the ground up. It still is faulty in the anti-theft module or circuit though, when i

Resetting is a temporary fix to a larger problem. A 96 grand am runs the Vats system. These systems do not relearn the key or ignition. They use that "chip" in the key shaft. So the fact that the "reset" temporarily fixes the problem leads to one thing. A failed theft deterrent module. (TDM) In order to fix this problem, you will need to replace the TDM or bypass the system entirely. I would lean toward bypassing the system. That way you never need to worry about it again, can be done yourself, and for cheaper than a TDM. Go to this link and look under PERMANENT FIX.

1996 2.4 grand am acts like its trying to start but shuts off. fuel is getting up to front fuel pump work but car doesn't start

you should have the fuel pressure tested with a gage as if its too low it will not start.without the gage you won`t know the what the pressure actually is.also if you have anti-theft on the car it may have been activated not allowing the car to start.

96 grand am starts for 1-2 seconds and then dies- restart in a few seconds for another 1-2 seconds; new tank and fuel pump

did you change the fuel at the same time as the pump replacement.are you losing fuel pressure/volume that was checked with a gage(have seen it happen with a new pump).does your car have anti-theft on it,it could have set and not allowing the car to start and run.

Theift lite comes on wont let engine run. 1996 Grand AM SE

Common problem is the "chip" in the key wears with time and eventually won't function in the car's VATS (Vehicle Anti Theft System). The chip itself is actually a resistor. The ignition requires a particular resistance before it will allow the car to start. You can test this by trying another key that has the chip. If the other key starts the car, you've identified the problem and need another key. If not, the car has a security issue that will likely need to be diagnosed at the dealer.

Trouble starting once in awhile

it does sound like the anti-theft system. There are only 2 ways to bypass your problem. 1) disconnect the anti-theft system which runs into your ignition, cut the wires to the system and join them back together without hooking it back up to the anti-theft. 2) Bring it back to the dealer so that they can replace your anti-theft sensor. The part is rather cheap but the labor is the killer.
