Have you checked the codes?
Mine was a faulty coil.... Twice. I made a heat shield for the second one.

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.

Are you positive its the fuel pump? Have you tried running the pump with the return line off to see if it pumps fuel? They don't always have to make a noise.

Have you changed the fuel filter? Did it die while driving, or just wouldn't start? Don't use starting fluid on a gas engine! It will cause a lot more problems than it solves. Ether, starting fluid is made for diesel engines... not gas, not ever. If it won't start, it isn't lacking ether. It's lacking gas, air or spark.

The fuel pump is in the fuel tank.Sit in the car.....turn on the ignition switch to run.....listen very closely to the rear of the car...or have someone kneel down by the back wheel.....you should hear a "prime cycle"......the pump running for 2 or 3 seconds if the key was off for 15 seconds before trying this.If you hear silence you most likely need a fuel pump.Before pulling the tank down....check for power on the gray wire at the fuel tank connector just ahead of the rear axle under the car.Check for power with a test light that will last for 2 to 3 seconds as you turn on the key to run.Power means you really most likely need a pump.No power means you may need a fuse or a fuel pump relay.

Hi sherri, A bit more details is needed for an accurate follow-up & diagnosis. Can you please add details in the comment box?
1. What were the symptoms before you changed the fuel pump? Also, what was done to verify/test that the old fuel pump was defective?
