My 1998 Sunfire 2200 Sfi Starts Up 4 3 Secounds Then Shuts Off Why? The Theft System Stays On

There is either a problem with your key or with the anti theft system in the car.

Do you have more then one key? Try the other one.

If not you will probably have to take the car to the dealer.

Check your harness of wire under the front bumper (about 75 wires)you should find some of them with corrosion or cut.just put it back together you should be ok
