SOURCE: how to change the fuel pump on a 1994 Mitsubishi Montero LS 3L V6

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.

  1. Lift or move aside the carpet in the rear cargo area.
  2. Remove the oval cover plate from the access hole.
  3. Disconnect the fuel pump harness connector at the rear of the fuel tank.
  4. Start the engine, allowing it to run until it runs out of fuel. This relieves pressure within the fuel system.
  5. Turn the ignition switch OFF and disconnect the negative battery cable.
  6. Remove the fuel filler cap.
  7. Drain the fuel from the fuel tank into suitable container(s), each with an airtight lid.
  8. Carefully, and using two wrenches on the fittings, disconnect the high pressure fuel line and the main fuel line from the pump. Remove the high pressure fuel hose at the body-side main pipe connection, unfasten the pump-side connection. Wrap each joint in a rag before loosening; some pressure may remain within the system.
  9. Remove the fuel pump retaining nuts and carefully remove the pump from the tank.
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:
  1. Carefully install the pump into the tank and install the 6 retaining nuts onto the studs. Tighten the nuts evenly and in a crisscross pattern to 12 ft. lbs. (16 Nm).
  2. Reinstall the high pressure and supply line to the pump.
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).
  1. Connect the pump wiring harness.
  2. Connect the negative battery cable. Turn the ignition key to ON but do not start the engine. You should hear the pump running. Allow it to run for about 10 seconds to build line pressure, then start the engine.
  3. After the engine has run smoothly for a minute or two, shut the ignition off and check the work area for any trace of leakage. Attend to any fuel leaks immediately, remembering that the system has repressurized and must be handled safely.
  4. Reinstall the cover on the access hole and replace the carpet in the cargo area.
0900c152800547c3.jpgFig. 1: Components of the fuel pump and fuel tank 0900c152800547c4.jpgFig. 2: Components of the fuel pump-all models similarTESTING
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: location of fuel pump relay (1990 hyundai sonata)

The fuse box is located low on the left side of the dashboard behind a cover, or at the left side kick panel, behind a cover.

Relay Box -is located under the left side of the dash as well.

SOURCE: fuel pump NOT working ,fuel pump is OK,but no voltage

Check the voltage with someone cranking the engine. The fuel pump relay is incorperated in the FI relay located under right center of dash. It is a metal relay usually bolted to the floor near the ecm. Double check all the fuses inside and out

SOURCE: I don't here the fuel pump ever kick on in my 1990 Ford F150, and I tested all of the fuses and they are good. I was thinking the relay for the fuel pump might be bad -- any suggestions?

It's under your hood, in one of those boxes, and should be marked. Your pump won't cut in if it's fried either. Check to see if there is power at the pump. Maybe you just have a loose wire. You can always hope!

Does vehicle engine turn over. If yes, then pay attention to fuel system. Check for good power and ground at fuel pump connector. If no power check fuel pump fuse, relay and for open wires (power, ground) to fuel pump.

2002 Mitsubishi Montero Sport (won't not 'want') start. Replaced the starter and fuel pump. Filter still not getting gas to the cylinders


If you already replaced fuel pump and filter and still no fuel pressure at injectors rail, your problem is more than likely electrical. Check for good power and ground at fuel pump connector. If no power at fuel pump connector, check your fuel pump fuse, relay and wiring for opens(broken) feed wire.

What is the fuel pressure suppose to be on a 1990 mitsubshi montero sport


Difficult question to answer directly. There's a pressure regulator on the end of the fuel rail that's set to around 35 psi. The fuel pump can deliver more than this of course, but the regulator is there to return excess pressure to the tank. Perhaps your problem is the fuel pump or the MPI relay which is usually behind the center console.

check for spark and gas by trying to spray starting fluid into the intake and trying to start it. If it starts and runs for a few seconds, then it's a bad fuel delivery system or possible fuel pump.
