Well, the anti-theft system should prevent the engine from cranking and starting. So if it will crank and start then die, it could be a long list of things. You would need to figure out if it is fuel or ignition related to proceed.
The security light usually means the computer is not accepting the chip in the key. Either the chip is bad or the sensor in the lock cylinder.

Try resetting the security. Turn the key to on and leave there for 10 minutes. Does the light go off? If it did go off, try starting the car. If the security light stays on, or comes back on with key on and won't go out within seconds, you will have to get the system diagnosed. The theft deterrent module in GM cars is very expensive.
Here is a site with information on disabling the system, by buying a module for under $200 that entirely bypasses the security:

SOURCE: car starts run's 3 seconds shuts down

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.

PASSKEY LOCKOUT RESET GM CARS 1999 UP
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: 97 pontiac bonneville se airbag light stays on all

Here's a quick check list for most common cost of SRS / Air bag problem.

Dirty contacts on driver and passenger seat belt buckles

Dirty contacts on seat belt connectors (under seats)

Dirty contacts on driver and passenger sides weight sensors (under seat)

Seat covers

Weight on passenger seat
(Example: grocery package trigger SRS / Air Bag light on the way home.)

I recommend you to pass an vacuum over the contacts and use CRC electronic parts cleaner to rule out connectivity problem.

I DO NOT recommend disconnecting the negative battery connector to clean the code(s).

Without the code(s) the dealer will takes "BILLABLE" time to reproduce the problem.

Please rate my answer if it is useful to you.

Cheers,

Would a plugged fuel line return line cause my 2004 pontiac bonneville to start then run for alittle then stall?


Fuel Pressure regulator ..maybe

Turn the Key to the 'ON' position, the fuel pump should run for about 1 second. listen for it. Do this a few times without trying to start the car. This should pressurize the system. now try starting the car. There may be air in the system from changing the filter.
