Hello,
It sounds like the key interlock unit might be bad, but to be sure lets remove the fuses # f4 and #f17 to see if the problem stops. Here are the fuse locations and the shift interlock wiring diagram so you can see how it works.
Check out the diagrams (below). Please let us know what you find.
Cheers, Ken
