I do know the fuses are good........as far as the ignition switch goes, you can take the key out when the car is running but that has been like that since I bought the car 4 yrs ago. I'm leaning towards some type of solenoid inline between the brakes and shifter. Some type of safety catch or something. You can tell the button is locked by the way it feels when you try to press it, and there is no jigglin' or pulling or pushing that is going to move it. The connection is broked somewhere. The car sets low with ground effects and I don't have the equipment at home to get it off the ground enough to check underneath.
