The fuel pump does not stay on with the key in the on position. Just long enough to build up pressure in the system, then shuts down. If you know your way around a multi meter then begin checking for power to the inertia switch. If it melted I suspect an overload.

What should the meter read?

I do not have a schematic for the vehicle, however, if it is a switch it should be getting twelve volts.

Ok. I borrowed a code reader and it said "no power train DTCs or Freeze Frame stored in vehicles computer". What does that mean? And could that be the cause of my misfire?

Digital Trouble Codes These are set when a problem is detected while the vehicle is running, normally. The computer in you vehicle has not detected any systems operating outside of normal perimeters.
