You need to find out what fault code is causing the security light to come on
that's why the vehicle will not start
repair that and the vehicle should start
hope this helps

POSSIBLE - * MAF sensor (Mass Air Flow Sensor) has gone BAD causing car to start then shut back off . * Security has kicked in ( Due to changing stereo system or battery went dead or didn't have one on it for a little while .
FIXES - *Replace Mass Air Flow Sensor (in between the throttle and the air filter box) . * Take to Dealer and have computer Flashed/Reset if SECURITY is at Fault . I recommend the MAF sensor

I have a 2000 blazer when driving down the road it will shut off then turn the key off for few second and start right up and the battery is always dead down we change the fuel pump and filter and its is...


Almost sounds like a Alternator issue or even a bad battery might want to have them checked. If your alternator is going out the battery may not have enough juice to keep the fuel pump going this is the reason it will shut off. If your battery is bad then it will not hold the charge.

These vehicles are known for faulty antitheft systems. When they start to fail, the car turns off the fuel injectors as a theft deterrent. Next time it stalls, look for a light on the dash that says SECURITY or ANTITHEFT. If you see this light, this link will help you.

I changed fuel pump and fuel filter. My battery went dead. I took battery out and recharged. Now I'm locked out by my security, Engine won't turn/start. I think I'm locked out by security system.


Turn the car on, dont try to start it, let it set ten minutes, turn it off dont take the key out. do this three times. on the third time turn it off then try to start. this will reset the security. Make sure you have everything turned off when you do this. as the battery will drain. It is a good idea to put the charger on the battery as you do this.

1996 Pontiac Grand Am will start but won't stay running


Either security chip in the ignition switch has failed or the security system has triggered. Try turning the key on and let the security light flash till it goes on steady. If it does not start, change ignition lock.

Will not start


Open the air filter container. Spray some starting fluid in and see if it starts. If it starts, it is the fuel filter or fuel pump or both.
