2009 Mitsubishi Galant Fuel Pump Relay Location: A Complete Owner's Guide

The fuel pump relay on a 2009 Mitsubishi Galant is located in the passenger compartment fuse box, which sits on the end panel of the dashboard behind an access cover. This is the primary relay that controls power delivery to the fuel pump inside your fuel tank. There is also a second fuel pump relay in the same fuse box, and a fuel pump fuse in the engine compartment fuse box that you should be familiar with when troubleshooting fuel delivery problems.

Where Exactly Is the Fuel Pump Relay?

On the ninth-generation Mitsubishi Galant (2004–2012), the passenger compartment fuse box is mounted on the end panel of the dashboard, typically on the driver's side. To access it, open the driver's door and look at the side of the dashboard—you will see a small plastic cover that can be pulled off by hand or with a flathead screwdriver. Behind that cover is the fuse box with all the interior fuses and relays .

In this fuse box, you will find two fuel pump relays. The primary fuel pump relay is labeled as the first relay position, and there is a second fuel pump relay positioned nearby. Both are standard automotive relays that can be pulled straight out of the socket once you locate them .

Engine Compartment Fuse Box: The Fuel Pump Fuse

While the relay lives inside the cabin, the fuel pump fuse is located in the engine compartment fuse box on the driver's side, right next to the battery . This fuse is rated at 15 amps and is labeled in the fuse box diagram. If your fuel pump is not getting power, this is the first thing to check before you start digging into relays or the pump itself .

How the Fuel Pump Relay Works on the Galant

The fuel pump relay acts as a switch that sends battery voltage to the electric fuel pump inside the fuel tank. When you turn the ignition key to the "ON" position, the Engine Control Module (ECM) energizes the relay for a few seconds to prime the fuel system. Once the engine starts, the relay stays closed and keeps power flowing to the pump while the engine runs .

If the relay fails, the fuel pump will not receive power, and your engine will crank but not start. You may also hear no priming sound from the fuel tank when you turn the key to "ON" .

Fuel Pump Location on the 2009 Galant

The fuel pump itself is mounted inside the fuel tank, which sits beneath the rear seat area . The pump is part of a complete module assembly that includes the fuel level sending unit, the strainer, and in some configurations, the fuel filter. On this generation of Galant, there is no separate, externally mounted fuel filter—the filter is integrated into the pump module inside the tank .

To access the pump, you have two options. Some Galant models have an access panel under the rear seat cushion that lets you reach the pump without dropping the tank. If your car does not have this access panel, you will need to lower the fuel tank from underneath the vehicle .

Symptoms of a Failing Fuel Pump Relay

Before you go hunting for the relay, here are the most common signs that your fuel pump relay or the pump itself is failing:

  1. Engine cranks but will not start. This is the most obvious symptom. If the relay is dead, the pump never primes, and there is no fuel pressure at the rail .

  2. You hear no whirring noise from the rear of the car. When you turn the key to "ON," you should hear a brief whine from the fuel tank area. If you do not, the relay or the pump is not getting power .

  3. The car starts after several attempts. A failing relay can sometimes make intermittent contact, allowing the pump to work only when it feels like it. This often shows up as extended cranking time before the engine fires .

  4. Check engine light comes on. Diagnostic trouble codes related to fuel pressure, such as P0087 (fuel rail pressure too low) or P0230 (fuel pump primary circuit malfunction), can point to relay or pump issues .

How to Test the Fuel Pump Relay

Testing the relay is simple and takes about five minutes. Here is what to do:

  1. Turn the ignition off and disconnect the battery negative terminal.

  2. Remove the relay from the fuse box. Pull it straight out—it should come out with moderate effort.

  3. Check for continuity. Using a multimeter, test the relay's coil terminals. You should see resistance in the range of 50 to 120 ohms. If you get an open circuit (infinite resistance), the coil is burned out, and the relay needs replacing .

  4. Apply power to the coil. Connect 12 volts to the coil terminals and listen for a distinct click. If you hear the click, the relay's internal switch is working. If you hear nothing, the relay is dead .

  5. Test the switch side. With power applied to the coil, check for continuity between the relay's switched terminals. You should get a closed circuit (near-zero resistance). If not, the relay's contacts are worn out .

Fuel Pump Relay Replacement Cost

A replacement fuel pump relay for the 2009 Galant is inexpensive—typically between $15 and $30 at an auto parts store. The replacement itself takes about two minutes and requires no special tools. You simply pull the old relay out and push the new one in. There is no need to reset anything or bleed the fuel system after replacing the relay .

Fuel Pump Replacement: What to Expect

If the relay tests fine but your car still has fuel delivery problems, the issue is likely the pump itself. Here is what you should know before tackling this job:

  1. The pump is inside the tank. On the 2009 Galant, the fuel pump module is located inside the fuel tank, accessible from under the rear seat. This means you will need to remove the rear seat cushion to reach the access cover .

  2. The pump module is an integrated unit. The 2009 Galant uses a fuel pump module assembly that includes the pump motor, the fuel level sending unit, and the fuel strainer. When you replace the pump, you are typically replacing the whole module, not just a standalone pump .

  3. OEM part numbers. For the 2005–2011 Galant, the fuel pump module is available under OEM part numbers 1760A223 and MR990883. You can also use aftermarket replacements from brands like Delphi or Airtex, which are direct fits for the 2.4L and 3.8L engines .

  4. Labor time. Replacing the fuel pump on a Galant takes roughly 2 to 3 hours for an experienced DIY mechanic. The job involves disconnecting fuel lines, removing the access panel or dropping the tank, and carefully swapping the module .

  5. Cost. A new fuel pump module for the 2009 Galant typically costs between $100 and $200 for the part itself. If you have a shop do the work, expect labor to add another $150 to $300 on top of the parts cost .

Important Safety Precautions

Working on the fuel system is dangerous, and you must take proper precautions before you start:

  1. Relieve the fuel system pressure first. Locate the Schrader valve on the fuel rail, cover it with a rag, and press the valve stem to release pressure. This prevents fuel from spraying when you disconnect the lines .

  2. Disconnect the battery. Always disconnect the negative battery cable before working on any fuel system component. This eliminates the risk of sparks igniting fuel vapors .

  3. Work in a well-ventilated area. Fuel vapors are highly flammable. If you are working in a garage, open the doors and keep any ignition sources far away .

  4. Have a fire extinguisher nearby. It is better to have one and not need it than to need one and not have it. Keep a Class B extinguisher (rated for flammable liquids) within reach .
