2006 Mitsubishi Galant Fuel Pump Relay Location: A Direct Guide for Owners

If you drive a 2006 Mitsubishi Galant and the engine cranks but refuses to start, the fuel pump relay is one of the first components you should check. Here is the direct answer: The fuel pump relay on the 2006 Mitsubishi Galant is located inside the cabin, in the fuse box on the driver's side of the dashboard. To reach it, open the driver's door and remove the access panel on the side of the dash, just above the hood release. Inside that fuse box, the fuel pump relay is the switch on the far right at the bottom .

This guide walks you through everything you need to know about locating, testing, and replacing the fuel pump relay on your 2006 Galant. We will also cover related fuses, common symptoms of a failing relay, and what to do when the relay checks out fine but the pump still does not run.

Why the Fuel Pump Relay Matters

The fuel pump relay acts as a heavy-duty switch that controls the electrical current flowing to the fuel pump. When you turn the ignition key to the "ON" position, the engine control unit (ECU) sends a low-current signal to the relay. This energizes an electromagnet inside the relay, which closes a set of contacts and completes the high-current circuit from the battery to the fuel pump . This allows the pump to pressurize the fuel system for a few seconds before you crank the engine.

Without a working relay, the fuel pump never receives power. The result is a car that cranks but will not start, much like a failed pump itself. Because the relay is much cheaper and easier to replace than the pump, it is always worth checking first.

Where to Find the Fuel Pump Relay: Step-by-Step

The 2006 Mitsubishi Galant places its fuel pump relay in the interior fuse box, not under the hood. Here is how to access it:

  1. Open the driver's door and look at the end of the dashboard on the left side. You will see a small plastic cover panel .
  2. Remove the access panel by pulling it straight toward you. In most models, it pops off without any tools. If it feels tight, use a flathead screwdriver wrapped in a cloth to gently pry it loose.
  3. Locate the fuse box behind the panel. This is the junction block that houses fuses and relays for many of the car's interior systems .
  4. Find the fuel pump relay at the bottom of the fuse box. According to owner reports, it is the relay on the far right at the bottom row .
  5. Check the label on the back of the access panel or the fuse box cover. Mitsubishi typically marks the relay with a symbol or abbreviation. If the label is faded, the bottom-right position is your best bet.

Important note: Some 2006 Galant models may use two fuel pump relays, depending on the engine and trim level. Wiring diagrams for the 2.4L engine list both "Fuel pump relay 1" and "Fuel pump relay 2" . If you see two relays in the same area, both are part of the fuel pump circuit. Replace them one at a time and test after each change.

The Fuel Pump Fuse: A Related Component You Should Know

While you are inside the fuse box, it is smart to check the fuel pump fuse as well. A blown fuse produces the exact same symptoms as a bad relay.

  • Location: The fuel pump fuse for the 2006 Galant is actually in the engine compartment fuse box, not the cabin box. It is labeled as a 15A fuse and is listed as fuse number 24 in the main under-hood fuse block .
  • How to check: Pull the fuse out and hold it up to the light. If the metal strip inside is broken or discolored, the fuse is blown. Replace it with a 15A fuse of the same type.
  • What else to inspect: The same engine bay fuse box also contains relays for the MFI (multi-port fuel injection) system and the throttle actuator control motor. These are separate from the fuel pump relay but are part of the same fuel delivery circuit .

If the fuse is good and the relay clicks when you turn the key, the problem likely lies elsewhere in the fuel system.

How to Test the Fuel Pump Relay Without Special Tools

Before you buy a replacement relay, you can test the unit you already have. Here is a simple method that works on most automotive relays:

  1. Turn the ignition key to "ON" without cranking the engine. Have a helper listen near the fuse box or place a finger on the relay.
  2. Feel and listen for a click. When the relay energizes, you should hear a soft, distinct click and feel a slight vibration. This means the relay coil is receiving power and the contacts are closing .
  3. Listen for the fuel pump. At the same time, have someone stand near the rear of the car near the fuel tank. When the relay closes, the pump should make a brief humming or whirring sound for about two seconds .
  4. If no click, no hum: The relay is not receiving its trigger signal, or the relay coil is dead. Try swapping the fuel pump relay with an identical relay from another circuit in the same fuse box, such as the horn relay. If the car starts with the swapped relay, you have confirmed the original relay is faulty.

This simple test takes less than two minutes and can save you from replacing parts that are not broken.

What to Do If the Relay Is Fine but the Pump Does Not Run

If the relay clicks, the fuse is good, and you still hear no sound from the fuel tank, the problem may be the fuel pump itself. On the 2005–2011 Mitsubishi Galant, the fuel pump is a module located inside the fuel tank, accessible from under the rear seat . Accessing it requires:

  1. Removing the rear seat cushion to expose the access plate on the floor pan.
  2. Removing the access cover to reveal the fuel pump module on top of the tank.
  3. Disconnecting the electrical harness and fuel lines before loosening the locking ring that holds the module in place .

Before you go that far, however, check the wiring. Trace the harness from the fuel pump connector back toward the fuse box. Look for chafed wires, corrosion, or loose terminals. A poor ground connection is also a common cause of fuel pump failure .

Another possibility is the fuel pump relay number 2, if your model has one. Wiring diagrams show both relays are part of the same circuit for the 2.4L engine . If you only swapped the first relay, verify the second one is working as well.

Common Symptoms of a Failing Fuel Pump Relay

Knowing the warning signs helps you catch a bad relay before it strands you. Look out for these symptoms:

  1. Engine cranks but will not start. This is the most common and obvious sign. The starter turns the engine over, but the fuel system never pressurizes.
  2. Intermittent stalling. The engine may run fine for a while, then suddenly die while driving. After a few minutes, it restarts. This suggests the relay contacts are worn and intermittently losing connection .
  3. Loss of power under load. If the relay is weak, it may not deliver full voltage to the pump. The engine may hesitate or sputter when you accelerate hard.
  4. No priming sound. When you turn the key to "ON," you should hear a brief hum from the fuel tank. If the tank is silent, the relay is not closing, or the pump is not getting power .
  5. Long cranking time. The engine may take several seconds of cranking before it fires. This means the fuel system is losing pressure, often because the pump shuts off too early due to a bad relay.

If you experience any of these, start with the relay. It is the cheapest and easiest fix.

Reliability and Replacement Considerations

The 2006 Mitsubishi Galant was produced during the ninth generation of the model, which ran from 2004 through 2012 . Many of these cars are now more than two decades old, and electrical components like relays wear out over time. Heat, vibration, and repeated cycling all take their toll on the relay's internal contacts.

When you replace the fuel pump relay, use a genuine Mitsubishi part or a high-quality equivalent from a reputable brand. Avoid cheap no-name relays that may not handle the current load reliably. The relay should click firmly when it energizes and stay cool during operation.

If you have already replaced the relay and the fuse, and the pump still does not run, it is time to test the fuel pump itself. You can check for voltage at the pump connector using a multimeter while a helper turns the key to "ON." If you see battery voltage for a couple of seconds, the pump is receiving power and the problem is internal to the pump. If there is no voltage, the issue is in the wiring between the relay and the pump.

Final Checklist for Your 2006 Mitsubishi Galant

To summarize everything covered in this guide, here is a quick troubleshooting sequence when your Galant cranks but will not start:

  1. Check the fuel pump fuse in the engine compartment fuse box. It should be a 15A fuse, located in position 24 .
  2. Listen for the relay click from the driver's side dash fuse box.
  3. Listen for the pump prime from the rear of the car near the fuel tank.
  4. Swap the relay with an identical one from the same fuse box to test it.
  5. Check both fuel pump relays if your model uses two relays .
  6. Test for voltage at the fuel pump connector under the rear seat.
  7. Replace the pump if it has power but does not run.

The fuel pump relay on the 2006 Mitsubishi Galant is easy to reach and simple to test.
