My car will not start and says its not in park. I changed the plugs, battery, fuel pump, fuel

Yes. It will act like it wants to start it want turn over. It was making a clicking noise passenger side right befofe it stopped running. It smells of gas inn the trunk area bad since its been parked. The fuel shut off thing in the trunk had a rattle noise in it like something was maybe broken in it. It feels like there's a magnetic in it.(is there)

Yes there is a magnet and a metal ball inside the inertia switch - so much for that. Possible fuel leak - TEST fuel pressure - likely find a YouTube video showing how. Good luck!
