Something has happened to the security, you don't have it anymore. The computer went to default mode and lets the car run. You can either fix the problem(you have to take it somewhere to have it scanned) or remove the instrument panel and take out the light, Or you can live with it..I would just live with it.

SOURCE: security system wont let car start

It sounds like the security system has been activated so you need to roll down the drivers side window and close the door. Reach in and turn on the key to the Run position and leave in on for 10 minutes. After 10 minutes is up, turn off the key and then try to start the car. The car should start. If it doesn't start do the process over again. This usually fixes the problem. There is no way to turn off the security system unless you have a key fob. If you have the key fob, just unlock the car and that will disable the security system. I hope this has been helpful.

SOURCE: abs and traction control light faults after a brake job. 2005 Pontiac grand prix

You have a bad sensor at one of the tires that need replacing that operates ABS and traction control. If you take it in to a shop it will run $130 but they can find which sensor is causing the problem. But if you do it you might have to replace all 4 sensors to make sure you got the right one. Every hard to diagnoses. Its better for the shop cause they can get electrical read outs for each sensor.

SOURCE: starts and runs 3-5 seconds and shuts down

Sounds like your security system is shutting the car down. You should be able to leave the key on for 15 minutes and it will reset itself. Make sure you are using factory keys, and they are in good condition.

My 1994 pontiac grand prix is not starting intermitently. My security light is on my dash and won't go off. It normally will start after a few minutes, but it is happening more and more. I got a new key...


There is no way to override the security system that I know of.You probably have a bad ignition cylinder.This is the part that the key goes into.Unless you know the resistance of that key and then you need to get a resistor of that resistance and put it in the wiring from the ignition cylinder on the wire that goes to the pcm.This will enable the pcm to allow fuel to the engine.Hope this helps.Good luck.

1994 gp 3100 ,wont start, turn key getting all the dash lites but starter not engaging, security lite is flashing, the car was drove to my hse i know it runs any ideas, battery is new, key is a #7.with key...


You need to set the parking brake, Turn the key on let it sit like that for 10 mins. the sec light will either start flashing or will stay on or go off when done (This will reset)
REPEAT 3 times!
Then you should be able to start the car after the 3rd time!
