I have a 1993 Dodge W-350. Last night, I went to start it up and all the accessory lights come on including "Wait To Start". The key turns to the start position and nothing. Once the key is in the start position, it feels really loose in a turning sense. It goes all the way to the end of the key position and doesen't do anything. The truck has 220,000 miles. Could it be the key switch, fuel shutoff solenoid, etc. ? This is just odd for it to stop starting, TIA.
