Hi,
Do you mean when the key is turned to the start position, the starter doesn't engage? Please explain.
If that is the case, confirm fuse 5 in the power distribution box under the hood is good and has power to and from it. Additionally, remove the starter relay and switch it with a different one having the same part number and see if that makes a difference.
I attached the wiring schematic below for the starting circuit for your reference. Additionally, here are two links you may find helpful:

Let me know if that is what is happening. Also, see if it will start if you place it in neutral.
Take care,
