Is your truck automatic or manual?
Have you tested for voltage at the starter yet?
Ok. The click you are hearing- is it a quiet click or a loud clunk?
Do you have a multi-meter to do some testing?
So you will want to test to see what voltage you have at the battery, should be about 12.5 volts or so and then test for 12 volts at the battery cable running to the starter all the way down at the starter.
Next you will need a helper to test the starter solenoid.
To test the solenoid you will unplug the solenoid trigger wire and then have someone else turn the key to crank while you watch for 12 volts on the trigger wire.
If the starter has 12 volts, the solenoid has 12 volts in the crank position, then the starter has to be bad.
If you don't get 12 volts at the trigger wire of the starter then you should suspect the ignition switch. We can do some testing from there if it looks like you aren't getting voltage at the trigger like you should.
I need to step out into the shop for a little bit. Let me know how the voltage testing goes.
Sounds good. Let me know if you get stuck.
