2001 Mitsubishi Galant Fuel Pump Location: The Complete Guide to Finding and Replacing It
The bottom line: The fuel pump on a 2001 Mitsubishi Galant is located inside the fuel tank, and you can access it by removing the rear seat cushion—no need to drop the fuel tank. For the 2.4L 4-cylinder engine, the fuel pump assembly is mounted on top of the fuel tank directly under the rear seat . If your Galant won't start and you don't hear the fuel pump prime when you turn the key, checking the fuel pump fuse and relay should be your first step before assuming the pump itself has failed .
Understanding Your 2001 Mitsubishi Galant Fuel System
The 2001 Mitsubishi Galant is the eighth generation of this popular midsize sedan, also known by the chassis codes EA1, EA2, EA3, EA7, EC1, EC5, and EC7 . It came with either a 2.4L 4-cylinder engine or a 3.0L V6 engine . Both engines use an electric fuel pump mounted inside the fuel tank. The pump delivers fuel from the tank to the engine under pressure, and when it fails, the engine either won't start or will stall while driving.
Knowing exactly where the fuel pump is located saves you time and money. Many owners assume they need to drop the fuel tank, but that's not the case with this model. Access is straightforward once you know where to look.
Where Is the Fuel Pump Located on a 2001 Mitsubishi Galant?
The fuel pump is under the rear seat, inside the fuel tank. You do not need to remove the fuel tank to access the pump. The pump assembly sits on top of the fuel tank, and there is an access cover on the floor pan beneath the rear seat cushion .
Here is the step-by-step process to locate the fuel pump:
Step 1: Prepare the vehicle. Park the vehicle on a level surface and turn off the engine. Make sure the gas tank is less than a quarter full to make it easier to access the fuel pump assembly and reduce the risk of fuel spillage .
Step 2: Disconnect the negative battery cable. Use a socket wrench to loosen the nut on the negative battery terminal. Move the cable away from the battery to prevent any accidental electrical shorts or sparks .
Step 3: Relieve the fuel system pressure. Locate the fuel pump fuse in the fuse box under the hood. Remove the fuse. Start the engine and let it run until it stalls. This relieves the pressure in the fuel lines. After the engine stalls, turn the key to the off position. Open the fuel tank cap to release any remaining pressure .
Step 4: Remove the rear seat cushion. The rear seat bottom cushion is held in place by clips. Pull the front edge of the seat cushion upward to release the clips, then lift the cushion out of the vehicle .
Step 5: Locate the access cover. Once the seat cushion is removed, you will see a metal access cover on the floor pan. This cover is directly above the fuel pump assembly. Use a screwdriver to remove the screws holding the cover in place. Lift the cover to reveal the fuel pump .
Step 6: Identify the fuel pump assembly. Under the access cover, you will see the top of the fuel pump assembly, which includes the fuel pump module, electrical connector, and fuel lines. The pump itself is inside the assembly, submerged in the fuel tank .
Common Symptoms of a Failing Fuel Pump
If you suspect your fuel pump is failing, watch for these warning signs:
1. Engine cranks but won't start. This is the most common symptom. The starter motor turns the engine over, but the engine does not fire. You may also notice that you don't hear the fuel pump prime for a second or two when you turn the key to the "on" position .
2. Engine stalls while driving. If the fuel pump fails intermittently, the engine may stall without warning while you are driving. This can be dangerous, especially at highway speeds. The car may restart after a few minutes once the pump cools down .
3. Loss of power under load. A failing fuel pump may not deliver enough fuel pressure to the engine when you accelerate hard or drive uphill. You may feel a lack of power or hesitation.
4. Poor fuel efficiency. A worn fuel pump can cause the engine to run rich or lean, leading to reduced gas mileage.
5. Whining noise from the fuel tank. A healthy fuel pump makes a quiet hum. If you hear a loud whining or buzzing sound coming from the rear of the vehicle, the pump is likely failing.
Checking the Fuel Pump Fuse and Relay First
Before you replace the fuel pump, always check the fuel pump fuse and relay. A blown fuse or a faulty relay can mimic the symptoms of a bad fuel pump. This is a quick and cheap fix that can save you hours of labor.
Fuel pump fuse location: The 2001 Mitsubishi Galant has two fuse boxes: one under the hood and one inside the passenger compartment . The fuel pump fuse is typically located in the engine compartment fuse box. According to the fuse box diagram, fuse #11 in the under-hood fuse box is a 20A fuse that protects the fuel pump . Another source indicates that the engine compartment fuse box contains a dedicated fuel pump fuse rated at 15A or 20A, depending on the specific model .
Fuel pump relay location: The fuel pump relay is also located in the engine compartment fuse box. It is labeled as relay R17 in some diagrams . The relay acts as a switch that supplies power to the fuel pump when the engine is cranking or running. If the relay fails, the fuel pump will not receive power.
How to check the fuse: Pull the fuel pump fuse out of the fuse box using a fuse puller or a pair of needle-nose pliers. Look through the clear plastic housing. If the metal strip inside the fuse is broken or melted, the fuse is blown. Replace it with a fuse of the same amperage rating .
How to test the relay: Swap the fuel pump relay with another relay of the same type in the fuse box (for example, the horn relay or the fog light relay). If the fuel pump starts working after the swap, the original relay was faulty .
Step-by-Step Guide to Replacing the Fuel Pump
If you have confirmed that the fuse and relay are good, and the fuel pump is not working, you will need to replace the fuel pump assembly. Here is a detailed guide:
Tools and parts you will need:
- New fuel pump assembly (compatible with 2001 Mitsubishi Galant)
- Fuel line disconnect tool (size 5/16 inch or 3/8 inch, depending on your model)
- Socket wrench set
- Flat-head screwdriver
- Philips screwdriver
- Clean rags
- Safety glasses
- Gloves
- A bucket to catch any fuel spills
Step 1: Disconnect the negative battery cable. Use a socket wrench to loosen the nut on the negative battery terminal. Move the cable away from the battery .
Step 2: Relieve the fuel system pressure. Remove the fuel pump fuse from the fuse box. Start the engine and let it run until it stalls. Turn the ignition to the off position. Open the fuel tank cap to release any remaining pressure .
Step 3: Remove the rear seat cushion. Pull the front edge of the rear seat cushion upward to release the clips. Lift the cushion out of the vehicle .
Step 4: Remove the access cover. Use a screwdriver to remove the screws holding the metal access cover in place. Lift the cover to expose the fuel pump assembly .
Step 5: Disconnect the electrical connector. Unplug the electrical connector from the top of the fuel pump assembly. This connector provides power to the fuel pump and sends the fuel level signal to the gauge .
Step 6: Disconnect the fuel lines. Use the fuel line disconnect tool to release the fuel supply and return hoses from the pump assembly. Be careful, as some fuel may still be in the lines. Have a rag ready to catch any drips .
Step 7: Remove the retaining ring. The fuel pump assembly is held in place by a large plastic or metal retaining ring. Use a hammer and a flat-head screwdriver, or a special fuel pump removal tool, to turn the ring counterclockwise and remove it .
Step 8: Remove the fuel pump assembly. Carefully lift the fuel pump assembly out of the fuel tank. The assembly holds fuel, so tilt it slightly to allow the fuel to drain back into the tank. Place the old assembly in a bucket to catch any remaining fuel .
Step 9: Install the new fuel pump assembly. Before installing the new pump, transfer any necessary components from the old assembly, such as the rubber gasket or the fuel level sensor, if they are not included with the new pump. Ensure the new pump is properly aligned with the marks on the floor pan. Lower the new pump into the tank .
Step 10: Install the retaining ring. Place the retaining ring over the new pump assembly and turn it clockwise until it is tight. Do not overtighten, as this can damage the ring or the pump assembly.
Step 11: Reconnect the fuel lines. Push the fuel supply and return hoses onto the pump assembly until they click into place. Gently pull on them to ensure they are securely connected .
Step 12: Reconnect the electrical connector. Plug the electrical connector back into the top of the pump assembly. Make sure it clicks into place .
Step 13: Reinstall the access cover. Place the metal access cover back over the pump assembly and secure it with the screws.
Step 14: Reinstall the rear seat cushion. Lower the rear seat cushion back into place and press down firmly until the clips engage.
Step 15: Reconnect the negative battery cable. Reattach the negative battery cable to the battery terminal and tighten the nut.
Step 16: Prime the fuel system. Turn the ignition key to the "on" position for about 2 seconds, then turn it off. Repeat this process 2-3 times to allow the new fuel pump to build pressure in the fuel lines. Then start the engine. It may take a few seconds to start on the first attempt.
Step 17: Check for leaks. After the engine is running, check the area around the fuel pump assembly for any fuel leaks. If you see any leaks, turn off the engine and tighten the connections.
Why Your Car Died While Driving: A Real-World Scenario
One common scenario reported by 2001 Galant owners is that the car dies while driving, and the engine will not restart. The starter turns the engine over, but there is no spark and no fuel pump sound. The radio, lights, and other electrical components work fine .
In this situation, the problem is often a blown ignition or fuel injection fuse, not the fuel pump itself. Check all the large fuses attached to the positive battery cable and in the main fuse box under the hood. This fuse can blow when it detects a problem with the fuel system, such as a failing fuel pump that draws too much current .
If the fuse is blown, replace it with a new one of the same amperage. If the new fuse blows again immediately, there is a short circuit in the fuel pump wiring or the fuel pump itself has failed internally. In that case, you will need to replace the fuel pump.
Fuse Box Diagrams for Reference
The 2001 Mitsubishi Galant has two main fuse boxes: one under the hood and one in the passenger compartment . Here is a quick reference for the fuel pump-related fuses and relays:
Under-hood fuse box (engine compartment):
- Fuse #11 (20A): Fuel pump
- Relay R17: Fuel pump relay
Passenger compartment fuse box:
- Fuse #7 (15A): Cigarette lighter and accessory socket (not related to fuel pump, but often confused with the fuel pump fuse)
If you are working on a 2.4L engine, the fuel pump relay is located on the engine compartment relay box . The 3.0L V6 engine also has a dedicated fuel pump relay in the same relay box .
