Truck Won't start with key
 

1992 scab 5.8 4x4. turn the key and nothing happens. I can short the fender mounted solenoid out with a screwdriver with the key to on, but won't start with key. I don't get a click or anything. I turn headlights on and turn key to start and the lights don't dim at all. Is this my ignition switch or solenoid.

got it, replaced solenoid. Thank you ford for mounting on wheel well
