There is a fuse for the theft system, try pulling them out for a bit. Other than that leave the key in the On position for 30 mins as it's a security issue. Sometimes unlocking the drivers door with the key may help.

SOURCE: 96' sunfire changed engines 2.2 starts dies theft light comes on

The problem is the new PCM you installed does not have the correct VIN number of your car.
You may be able to relearn the VIN using the preceedure below, however, there is no gaurentee it will work. You may have to have a dealer reset the VIN for you by way of a scan tool.

1) Instert key into ignition and rotate to run position (do not try to start engine)
2) Leave the key in the run position for 10 minutes until security light stops flashing.
3) Turn ignition key to off position for 10 seconds ( no more, no less)
4) Turn ignition to run position again for 10 minutes until security light stops flashing and repeat step 3 and 4 for (1) more cycle.

The process is a security verification step for the VTD system. ( Vehicle Theft Deterent)

Give it a try, let me know.

Try starting it with the shifter in neutral. You might have a bad
Neutral safety switch.

My 96 sunfire will not start

Sure it is not getting any fuel? Then that is the problem. Check out fuel delivery system and components such as fuel pump, filter, injectors being fired, etc.

If the Vat system was activated the car would start but then almost right away after wards shut the engine down. But if you have had the battery disconnected you might just want to check out resetting it for "in case."

I have a f150 2000 v8 triton motor, i drove it the other day it started fine, than I went to start it again and it wouldnt start, than it started when i took to garage they said it was fuel pump and

If the anti-theft light is flashing, I would think it is a problem with the key or the anti-theft system. The system would kill the power to the fuel system.

Changed out battery to new one now car will not start with key but can jump solinoid and start 97 sunfire 2.4l

Are you getting any anti theft lights? The sunfire is pretty similar to the cavalier, and I worked on a 96 that had a problem with the passlock system.

If you are not familiar, you can turn the key but nothing happens. There is a yellow "anti-theft" light that blinks on the gauges. There is a resistor in the ignition switch that sends a signal to the computer to tell the car to start.

Your problem sounds similar, and since you just changed the battery, you may have reset the system. To re-enable it you unfortunately have to go to the dealer. I searched EVERYWHERE and found no quick fix for it, and I took the cavalier to the dealer as well. Hope thats not your issue, but if so let me know I will try to help however I can.

1996 sunfire replaced motor engine won't fire.Auto theft light stay's on don't blink stay's on

If the theft light isn't blinking then it likely isn't the problem. Does it start and die or just crank and won't fire?
