My 02 Olsmobile Alero won't start

The other day while driving, I noticed that when i pressed on the gas petal i wasn't accelerating so i pulled of to the side and my car shut off and now it wont start... the TRAC OFF and security lights are on. First thoughts are maybe the fuel pump, but any sugeestions and help are greatly appreciated...

Welcome to AF, engine size here is critical. Number 2, is the Sec. lite staying on? does the engine crank over?

I have an Ecotec 2.2 Engine and yes the security light stays on solid (isn't blinking).

...the engine cranks over but immediately shuts off

Sounds like a Passlock problem maybe. Passlock prevents fuel from getting to the engine when it thinks the wrong key is in the ignition. Search here, many people have had this problem.

Hey nire227, try this !

Security relearn procedure:

1) Attempt to start the car by turning the key to the Start/Run Position.
2) Observe that the vehicle fails to start and that the security light is illuminated.
3) Release key to the 'ON/Accessory' Position. (DO NOT turn key to the 'off' position.)
4) Allow the vehicle to sit with the key in the 'ON/Accessory' Position for no less than 11 minutes.
5) Turn key to off position and allow the vehicle to remain in the 'OFF' position for no less than 30 seconds.
6) Repeat #1 - #5 for 3 cycles.
7) On 4th attempt, car should start.

NOTE : Since this is a fairly long procedure, I would limit all electrical sources, such as disconnecting headlights, to prevent discharge of battery.

NOTE 2 : It is SAFE to wait LONGER than the allotted time, but it is not safe to wait less time. I.e. 12 minutes instead of 11 minutes should be safe; however, waiting 10 minutes instead of 11 minutes is not safe.

Properly executed, this procedure should take approximately 35 minutes to complete

I have had good luck using that exact procedure, but I never had to repeat it more than once. In other words, I only waited 10 minutes one time. Then I turned the key off, and the car would start the next time I tried to start it.
