If the vehicle starts in neutral but not park, then that is normally always the park neutral switch that has failed.
So, we need to jump the switch when in park and see if the engine will start.
Also, we can check the voltage going to and leaving the switch.

I am attaching the wiring diagram below and that will help with checking this switch that is on the left side of the transmission.
Please run through this and let me know what questions you have.
Thanks
