Nothing happens when I turn the key. The battery is good.

It sounds like the starter motor has gone bad, but to be sure let's check for power at the starter trigger wire.

Here is a guide that can help:

Also try to start the engine in neutral and let me know.

Here is how to change the starter out in case you need it. Check out the images (below). Please let us know what happens. I have included the starter wiring diagrams so you can see how the system works, also please check out the starter relay if the trigger wire is not getting power.

Okay, then we need to check the battery connections and then the fusible links.

Here is a guide to help:

https://www.2carpros.com/articles/everything-goes-dead-when-engine-is-cranked

I would test through the fusible link this guide should help and I have included the power distribution wiring diagrams so you can see how main power is fed into the vehicle.
