First, there are a few fuses that need to be checked and the starter relay. We need to start with a few checks.
First, take a look through this link. It explains in general how to test a starter.
If you look below, I attached the wiring schematic for the starting system. I will explain how it works.
First, I highlighted the wiring involved. The black wire that runs from the battery to the starter motor will provide 12v to the starter at all times. This is the larger, heavier gauge wire on the starter motor.
The other wires I provided show how power goes from the ignition switch to the 20amp crank fuse, through the neutral safety switch, to the starter relay, then to the starter motor S terminal. That should only have 12v power when the key is in the start position. When the starter relay gets power from purple wire with a white tracer, it closes the circuit in the relay and power travels from the red wire in the pic to the purple wire leading to the S terminal on the starter. That, in turn, engages the starter motor.
With that being said, we first need to check fuses. All fuses and the starter relay are located in the under-hood fuse box. The following need checked:
Ign A (maxi-fuse).
Also, if there is no power to the ign A fuse, we will need to check the 175-amp battery maxi-fuse.
If you look at pic 3, I highlighted the fuses in the under-hood fuse box to check. Also, I highlighted the relay. When you check these fuses, it is important to not only check the fuse for integrity but also confirm it is getting power to and from it. Here is a link to help:
As far as the starter relay, once you confirm the fuses are good, you can either check the relay or if there is another one with the same part number, switch them. Here is a link that explains how to test a relay.
Let's start with this and let me know the results. Also, please feel free to let me know if you have questions. I never know if the description and directions are helpful.
