Check your neutral safety switch on the transmission. It is either loose or out by a hair, that is why it work only some times.
If the starter makes no attempt to crank the engine and you did not disconnect the negative battery cable from the battery during the clutch job, maybe the battery drained from something left on while you had the truck apart (ignition left on, doors left open, etc).
the symptoms you describe sound like a starter problem. replace it and your problems will be through!

it could be the control module
if clicking but not starting dead battery if it starts it's one of the many relays that open and close during startup
A bad battery terminal(s) connection, bad ground, bad ignition switch, bad starter.

Seized engine? Loose or corroded battery cable? Bad starter solenoid on inner fender wall? Bad neutral safety switch? Bad ignition switch?

I had this problem on my disco 1. Turned out to be the alternator, which was replaced and the problem was fixed.
check the battery voltage, check battery cables, check ignition switch(where you turn the key), or check the crankshaft position sensor. cheers
