Looks like the security system (PassKey) is having problems, it's typical on those cars and it can get worse till the car wont start anymore. You can find a great write-up here: http://newrockies.ca

1998 sunfire want start


is the security light lit? try a different key to start.
if no start do the following.
try to start car then let go of key do not turn it off.
wait 15 min for security light to go out.
turn key off wait 5 seconds then try to start again.

the passkey system is not the best design, a little wear on the key and it won't start, if the tumbler wears out it won't start.

Truck stalled wouldn't start.


I can understand you being frustrated.
There really is no way to tell if the fuel pump was the problem at this point.
If the security system fails, you should see "security" light up on the cluster.
The key lock has a sensor that reads the chip in the key. If the sensor fails or the chip fails the computer won't let the vehicle start.
Most of the time when the security system is at fault, the vehicle won't start, but it won't cause the engine to stall.
You might want to have someone check the fuel pressure and spark at the plugs if you don't see the security light on the cluster.
Could be the fuel pump relay and a list of other things.
I would probably check the computer for trouble codes too.

Have an Oldsmobile 1997 Achieva security light stays on and won't everyhing but still won't start , would like to know would the Pro VATS Full Bypass work on it.


If the security light is on, then you have a failed antitheft system. This light is only for this. If you bypass the system, your car will work perfectly again.

Cherokee won't start it cranks but won't start and security light comes on


i dont know if this helps, but i know in some models, the security issue is caused by the key itself. if there is an rfid chip in the key and it is not responding to the computer, the motor will not start. try using your VIN to get a new key made at a dealership.

I have a 2001 Olds Intrigue that won't start every once in a while. When it won't start the security light flashes so GM told me it was the passcode and I would have to change the ignition switch...


you can not bypass the security in that car, it is built into the main computer, they have problems with the ignition switch screwing up and the only way to start it while the light flashes is to turn the key to ON but don't crank engine, leave on for 10 to 15 minutes until light goes out then start car.

Factory alarm started acting up a few days ago, now car won't start. only hear single click noise. managed to jump started it once


Could be the battery is dead or dieing. When batteries start to go they will cause the security to act up. Plus other things

When I try to start car, it won't start and security light blinks. I'v e had to ignition switches put on before and I had a new key made. Car still won,t start.


If any of the gauges are blinking and going haywire and the security light flashing then the instument cluster is faulty.But if it is just the security light flashing then its in the switch.If you only had the switch replaced then you need a new ignition lock cylinder because its worn out.
