The truck started not wanting to crank over all the time?

I would first confirm the trigger wire is hot in the crank position.

Here is a guide to help:

If not, I would swap out the starter relay which is located in the main fuse panel under the hood, here are the starter wiring diagrams so you can see how the system works. I also have included how to change the starter out if the trigger wire has power.

This step-by-step guide should help as well.

Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

Thank you! I'll have both checked.

Please let us know what happens.

The starter relay did not fix the problem. It will still sometimes just make a clicking noise but will eventually start.

It really sounds like the starter is bad, but can you confirm the trigger wire has power when the system is in the crank position? I would also use a breaker bar on the front of the engine to see if the engine turns over by hand, also I have seen a locked up front accessory on the engine cause this as well, you might want to try to remove the serpentine belt if the engine will not turn by hand.
