There isn't one. Easiest way to diagnose the fuel system is at the fuel pump relay. Make sure there is a good 12v supply and solid ground at the relay. Insert a jumper wire across the load side of the relay which would provide the pump a constant 12v supply. If it doesn't run, it's time to drop down the tank and see if you have 12v to the pump. If so, it's probably time for a new pump
Enter your vehicle from the passenger side and locate the fuel pump shutoff switch near the underside of the glove compartment, on the lower right side. The fuel pump cutoff switch has a small round button.
I have reset two inertia switches on cars because the were in an accident. I have never replaced one because it was bad. Replace the fuel pump. It's under the back seat.
Have you been in any type of a wreck? If so the inertia switch is located in the circuit between the fuel pump relay and the electric fuel pump(s). If you have been in a significant impact the mechanism inside the switch will cause the switch to open the electrical circuit, shutting off power to the fuel pump as a safety precaution. The inertia switch is in the cab on drivers side, up against the firewall, to the left of the brake pedal or behind the right kick panel. I would suggest buying a new one because it is not something you can reset.
Try looking underneath to see if you have possibly kinked or flattened a fuel line, if as you say, the fuel pump is running. Otherwise you may have jolted one of the injector sensors in the system.
