My truck is a 96 so this will work on 94 to 98 trucks with the 12 valve engine but I don't see why it wouldn't work on all the CTDs.
If your truck doesn't turn over and you think it is Neutral Safety switch, Clutch switch, Starter relay or the start position on the ignition switch.
You can use a solid wire(house wire) to start the engine. Turn the key to the run postion, go to the PDC (power distribution center) under the hood pull the starter relay put one end of the wire in the female terminal nearest to the battery and the other end into the oppossite terminal (toward the cab) until engine starts.
If your start position on the ignition doesn't work you will have to lift up the rod to the starter solenoid (12 valves).

You can also rule out the starter buy using this method.

I keep a 6 inch solid wire (with insulation on it) in my truck all the time.

The wire in the photo is inserted into the female terminal (hot) the other end is ready to be inserted into the opposite terminal (to starter solenoid and fuel shut off solenoid). You don't have to insert wire end into the female terminals just touch the female terminals.
