If you are hearing the starter relay click, chances are it isn't a power problem before it. Did you check fuse 40 in the under-hood fuse box? If not, check that. Also, confirm there is power to and from it. Here is a link you may find helpful.
If the fuse is good, I need you to check for power to the starter motor. At the starter, there will be a large red wire which has 12v at all times. Be careful not to short it. Additionally, there will be a smaller brown wire with a green tracer to the starter. That only gets 12v with the key in the start position. Have a helper turn the key to the start position while you check the smaller wire for 12v. If you get power, the starter is bad. If there is no power, let me know and we'll work backward to see where power is lost.
Here is a link you may find helpful when checking the wiring and checking the starter:
I attached the wiring schematic below for the starter circuit, so you have a reference.
Let me know what you find or if you have other questions.
