I think I would try a new ignition switch or at least unplug the switch after the engine is running and see if it stops running. When you initiate a start, a series of relays turn on in the powerbox. If the ignition relay is melted inside itself, it will not break connection. You can research and get diagrams, videos, and photos on the Web. Just be specific and enter the year, make, and model and ask for a wiring diagram or fusebox or powerbox for that truck. Then chose from the results.
You should be able to identify the correct relay from the diagrams. Relays are not terribly expensive.

The front crash sensor is on or near the radiator support under the hood, it is a little square box, one question why do you think it has a problem? it is a mechanical device, a steel ball bearing sitting in an inverted cone, when you crash the ball bearing breaks free of the magnet, that breaks a connection and signals the airbag monitor to fire the airbags, it takes a 5+ MPH impact to set all this in motion, there are side impact sensors as well, the physics of these are a little different, they are measured in G force of the impact, hope all this doesn't bore, one note the fuel that fires the air bag is made by the same folks that make rocket fuel for the solid fuel boosters of the space shuttle.
