The car im talking about is agrand am se 2000 v-6 3.4 motor,fuelpump comes on and it cranks up ,but want stay running, what could it be ?


Anti-theft system , is the security light lit on the instrument cluster ?

The vehicle theft deterrent system is designed in order to prevent vehicle theft by disabling the fuel injectors unless the lock cylinder is correctly engaged by a mechanical key. The theft deterrent system uses the following 4 components for theft prevention:
• The lock cylinder
• The ignition switch
• The body control module (BCM)
• The powertrain control module (PCM)
When starting the engine, the PCM searches for a password from the BCM through the Class 2 serial data circuit. If the password is not recognized or not present, the PCM will disable the engine. Two modes of tamper detection are provided:
No password received
The engine will start and stall quickly. SECURITY telltale will flash on the instrument panel cluster (IPC) and then stay ON steady.
Incorrect or disable password received (More than 3 invalid passwords are received)
The engine is disabled for at least 10 minutes and the SECURITY telltale will illuminate solid on the IPC during the 10 minutes.
After the vehicle has passed theft detection, the PCM will continue normal operation.
Auto Learn
Time required, approximately 10 minutes.
Insure that the battery is fully charged.
Use the scan tool in order to clear the DTCs.
Turn the ignition switch from the OFF position to the CRANK position attempting to start the vehicle. The vehicle will start and then stall.
Leave the ignition switch in the ON position while observing the security indicator.
When the security indicator turns off, which can take up to 10 minutes, turn the ignition switch off. Wait 10 seconds.
The BCM and the PCM will learn the new code on the next start attempt.

You can't do that an expect the vehicle to start , software programmed in the computer system . If the engine PCM doesn't see a pass word or coded message from the BCM or anti-theft module . IT will disable starting and or fuel injetor control .
Important: Due to component variability, the vehicle theft deterrent (VTD) system must have the learn procedure performed regardless, if the vehicle starts on the first ignition cycle after a VTD repair.
All codes in the theft deterrent module must be cleared for a relearn.

They do sell by pass modules you can find on the internet , in some cases it cheaper to have it fixed proper by a qualified repair shop . It just depends what the original problem was . You how ever just complicated matters by changing thing's .

One is under the hood in the engine compartment an Rear Fuse Block
Left rear of the passenger compartment, under the rear seat ! There are a couple of fuse's , but they power up the ignition an the PCM ,so you can't pull those ! Beside that if the PCM does not get a fuel enable signal from the anti-theft module the vehicle won't start . You can't just disable thing's on this vehicle ! If you have security light on steady or flashing you need to take it to someone who has a diagnostic scan tool that can check DTC'S - diagnostic trouble codes ! A code reader can not access these type codes !
Vehicle Theft Deterrent (VTD)Circuit Description
(VTD) Theft Deterrent System Components
Ignition Key (Transponder) The ignition key for the (VTD) theft deterrent system is a typical ignition key with a transponder pellet located in the plastic end of the key. The ignition key transponder value is used to determine if a valid ignition key is being used to start the vehicle, there are approximately three trillion different transponder values available. This vehicle has two types of ignition keys.
?€¢
Master key (black plastic end) which can start the vehicle and lock/unlock all door locks, all storage compartments and the rear compartment lid lock.


?€¢
Valet key (gray plastic end) which can start the vehicle and unlock/lock all doors, but can not unlock/lock the storage compartments, or rear compartment lid lock.

Important: The transponder values are not readable and can not be serviced separately.
Theft Deterrent Module The theft deterrent module contains the software for controlling the VTD System. The theft deterrent module uses the following inputs and outputs to control the VTD system.
Inputs ?€¢
Battery voltage from the underhood fuse block PCM/BATT fuse, circuit 240 (ORN).


?€¢
Ignition start voltage from the ignition switch, circuit 1390 (WHT).


?€¢
Ground, circuit 450 (BLK).
Outputs Password exchange with the PCM (fuel enable), class 2 message circuit 1807 (PPL).
Powertrain Control Module (PCM) The PCM verifies that the passwords received from the theft deterrent module via the class 2 serial data line are valid. If a password is invalid the PCM disables the fuel delivery system. If the password is valid the PCM enables the fuel delivery system.
Starter Relay The starter relay is controlled by the PCM module via class 2 serial data (CKT 1807 PPL). If the theft deterrent module measures the correct transponder value, the PCM module switches the starter enable control (CKT 447 YEL) to ground. The relay is energized if the ignition switch is in the START position and the gear selector is in the PARK or NEUTRAL positions.

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).

YOUR THEFT DETERRENT DONT RECOGNIZE THE NEW KEY AND SWITCH.YOU NEED TO TAKE TO DEALERSHIP LET THEM REPROGRAM IT.BECAUSE WHEN SECURITY LIGHT COMES ON WHILE DRIVING CAR THE THEFT DETERRENT SYSTEM AND PCM THINK CAR IS BEING STOLEN WHICH IT COULD SHUT OFF FUEL PUMP DISABLING CAR IN TRAFFIC WHICH CAN BE DANGEROUS.
