Does anyone know where the fuel pump cutoff/inertia switch is on a 1997 Montero Sport XLS?
Testimonial: "While the video was helpful, the cut off switch isn't there..."

drivers side, underneath the car. look at the line coming from the gas tank, and where the line gets bigger and has a metal cylinder in it, that is your fuel filter. a couple of clamps and you can change that thing out in a matter of minutes, and depending on your medel you may have to remove a metal plate to get to it.

just for you REMOVAL & INSTALLATION
See Figures 1 and 2
WARNING
In almost every case, replacing the Mitsubishi electric fuel pump requires removal of the fuel tank. Please refer to the fuel tank removal and installation procedure at the end of this section.
The fuel pump may still contain liquid fuel. Drain it into a suitable container with an airtight lid before performing any tests or inspections.
To install:
WARNING
Take great care when connecting the threaded high pressure lines. Start the threads by hand, then, while holding the hose side to keep it from turning, tighten the flare nut to 27 ft. lbs. (37 Nm).

When diagnosing engine problems, particularly a "no start" condition, the fuel pump function should be checked. Because of the difficulty in reaching the fuel pump connections, Mitsubishi automobiles have a conveniently located test connector under the hood. V6 Monteros have the connector taped to a wiring harness inside the right front kick panel, near the ECM and relays.
This connector bypasses all of the controls in the system (ignition switch, pump relay, etc.) and sends voltage directly to the pump. When power is applied to the pump you should be able to hear it running, although the in-tank pumps require you remove the fuel filler cap and listen at the filler.
To use the test connector, make certain the ignition is OFF. Great damage may be caused if the system is tested with the key on. Locate the test connector in the engine compartment (on later Monteros it is located under the right-hand side of the dashboard)-it is generally on a short lead out of a wiring harness and looks like a plug that isn't connected to anything. Once found, use a jumper wire to connect the test terminal to the positive battery terminal. Listen for the fuel pump; if it runs, you know the pump motor is good. While the pump is running, gently squeeze one of the fuel lines and confirm that the pump is delivering fuel pressure. If it does not run, the pump itself is most likely defective OR the connector to the pump is faulty.
When the pump is removed from the tank, it may be checked by applying battery voltage (+) to the connector and grounding the housing. Only run the pump for one or two seconds during this test; the pump can be damaged by running without liquid.
CAUTION
Make certain the pump has been drained of residual fuel and is free of fuel vapors. Connecting and removing the test leads will cause sparks which can ignite any vapor in the area.
SOURCE: 1990 montero no start. No power to open injectors, good fuel pump
Check the injector pulses with an osciliscope. If you arent getting a pulse check the ecu. I have cooked 2 of them. One killed my ignition but had good fuel. the second time it wouldnt open the injectors but had good spark. A quick check is to take the ecu out and take the cover off. then look for burnt electrical components.
