Hi:
This could be a few different problems. First, try starting it in neutral rather than park. If that makes a difference, we have an issue with the neutral safety switch.
If that doesn't help, locate the starter relay in the under hood fuse box. Switch it with a different one in the box that has the same part number.
I attached the wiring schematic below for your review. Try these two things and let me know what you find.
Take care,
Joe
