This could be a few things. The starter relay, a fuse, the starter, and the list goes on.
The first and easiest thing to do is see if it will start in neutral. There could be an issue with the park/neutral safety switch.
If it still doesn't start, I need you to check the ign A fuse and the starter relay. See pic 1. They are both in the underhood fuse box.
In addition to checking the fuse, make sure there is power to it. Here is a link you may find helpful:
Also, switch the relay with a different one in the box having the same part number. If there isn't one, here is a link that explains how to check one:
IF everything checks good, then we need to determine if there is power to the starter. On the starter, there is a heavy gauge wire direct from the battery. It always has 12v. There is a smaller wire that only gets 12v when the key is in the start position. You will need a helper to check it. If the smaller wire does get power, the starter is bad.
Here is a link that will help you:
Let me know what you find or if you have other questions.
Take care and God Bless,
