There are a couple things that can cause this but most likely this park neutral switch as failed if you are able to start the engine by jumping the starter.

Basically, this switch will prevent the starter from engaging unless it is telling the PCM that the vehicle is in park or neutral.
There is an adjustment procedure I attached below and if that does not work then we need to check voltage going in and out of the switch and if there is nothing coming out, then you need to replace it.

I attached the wiring diagram as well. Please run through this and let us know what you find. Thanks
