Interesting problem, on the starter is a "trigger" wire that originates from the ignition (may run to the power distribution center). When the truck is started 12 volts runs down that wire and activates the solinoid on the starter. Put a 12 volt test light on the trigger wire by the starter, have someone hit the key to start, test light should come on, if not chase wire back and look for a break in the wire or replace trigger wire.

If all cables and battery check out....make sure you have a good ground. If that is all good you need to check if you are getting battery voltage down to the solenoid with the key in the start position. If not most likely it's the ignition switch...if voltage is ok check connections at starter and again make sure ground is good. You should see battery voltage at the solenoid when the key is in the start position....at the battery cable and the smaller wire on the solenoid. If all checks out and still no-start...you need a starter.
