I have a 1988 Cutlass Supreme Classic (RWD) and with a viper alarm and it wont start. I turn the key and it turns all the way but it feels like theres not much resistance like usual and when turning the key the car makes no effort whatsoever to crank up. I dont hear any clicking noises or anything and with the key turned all the way the radio doesnt come on and none of the guage lights are on but the dome light comes on and the lights that come on when you open the drivers door still come on so the battery should be good. what could be my problem? broken ignition switch?
