If you get one click from the starter, either the starter has failed, you have a weak connection to the battery, or the engine is locked.
Do me a favor. At the starter motor, there will be a smaller gauge purple wire. That is the trigger wire. It only gets power when the key is in the start position.
Have a helper turn the key to the start position while you check for power at that wire.
I attached the starter circuit wiring schematic for the trigger wire below so that you have a reference.
Let me know what you find.
