Use your multimeter to test the resistance of the coil.
Compare it to the other bumper coils.
You may have to disconnect the wires to the coil and it will pay to check the diode while you are at it.

The same coil being used? Possibly the diode is open now?? For the 1 cent cost worth changing that first I would have thought.

Don't want to state the obvious but, you do have the power wire going to the correct end of the diode don't you?

Probably worth a clean - slide a business card between the contacts with light pressure to clean any grime off them, see if that improves things.
