93 F-150 just clicks when I turn the key
truck wouldn't start so I tapped the starter and it started. I have since replaced
the starter, solenoid (on the fender wall), ignition switch and the battery. I still
only clicks.
Sounds like you're getting voltage to the solenoid, but not the amperage to the starter. Try thoroughly cleaning all electrical connections, especially at the battery. Easiest and cheapest first thing to do.
Check the connector with the main hot wire itself to the starter they have a pinched on connector the wire corrodes inside of the connector and stays firm wiggle the wire see if it starts
