If the starter isn't engaging with the key, there are a few things that need to be checked. First, will it start in neutral? If not, then I need you to check a few fuses.
If you look below, I attached the wiring schematic for the starter circuit so that you have a reference.
First, in the under-hood fuse box, check ignition fuse 11 and crank fuse 46. In addition to checking the fuse, confirm there is power to them. Both fuses will require the key either in the run position or start position.
Here is a link you may find helpful:
If both fuses are good and have power to and from them, then we need to check the powertrain relay and the ECM Cont relay 31. If there are other relays with the same part number, switch them to see if it makes a difference. If there isn't, here is a link that explains how to test a relay:
If the relays are good, then go to the starter and check if the purple wire at the starter gets power when the key is in the start position. You will need a helper for this.
Let me know what you find. Also, the last pic shows the fuses and relays to check.
