2009 Nissan Murano Fuel Pump Location: A Complete Owner's Guide

The bottom line up front: On a 2009 Nissan Murano, the fuel pump is located inside the fuel tank, which sits beneath the rear seat area of the vehicle. To access it, you need to remove the rear seat cushion to reach the access panel mounted on top of the tank. This is a single in-tank electric fuel pump design, not a dual-pump system.

If you're experiencing hard starting, stalling, or a whining noise coming from the rear of your Murano, the fuel pump is often the first place to look. Knowing exactly where the pump lives and how to get to it can save you hours of frustration and a good amount of money in diagnostic fees. This guide walks you through the location, the symptoms of failure, and the step-by-step process of accessing the pump yourself.

Where Is the Fuel Pump on a 2009 Nissan Murano?

The 2009 Murano uses a single in-tank electric fuel pump. It is mounted inside the fuel tank, and the tank itself is positioned under the rear passenger area. The pump is part of a complete module that also houses the fuel level sending unit, the fuel pressure regulator, and a strainer (filter sock) . This entire assembly is accessible from inside the cabin.

To physically reach the pump, you do not need to drop the fuel tank. Instead, you access it through the floor pan. The process is straightforward:

  1. Remove the rear seat cushion. The bottom cushion is held in place by clips or bolts. Once removed, you will see a metal access panel on the floor.
  2. Remove the access panel cover. This is typically a round or rectangular metal plate secured by a few screws or bolts. Underneath, you'll find the fuel pump module .
  3. Disconnect and remove. Once exposed, you can disconnect the electrical connector and fuel lines to pull the entire module out.

This design makes the 2009 Murano much easier to service than many other SUVs where the tank must be dropped .

Understanding the Fuel Pump's Role

The fuel pump's job is to deliver fuel from the tank to the engine at a consistent pressure. In the 2009 Murano, this is an electric pump that is submerged in gasoline. Being submerged serves two purposes: the fuel acts as a coolant for the pump motor, and the liquid dampens the noise of the pump operating .

Key components within the fuel pump module include:

  • The electric motor: Powers the pump mechanism.
  • The pump mechanism: Typically a turbine design that physically moves the fuel.
  • The fuel filter (strainer): A mesh sock at the bottom that catches large debris before it enters the pump .
  • The fuel pressure regulator: Maintains consistent pressure in the fuel rail by returning excess fuel to the tank .
  • The fuel level sending unit: A float and resistor that sends the fuel level reading to your dashboard gauge .

The pump receives power through a relay and fuse, controlled by the Engine Control Module (ECM). When you turn the key to the "ON" position, the ECM activates the relay, powering the pump for a few seconds to prime the system before you start the engine .

Common Symptoms of a Failing Fuel Pump

Knowing the signs of a weak or failing pump can prevent you from being stranded. Here are the most common symptoms reported by Murano owners:

  1. Difficulty Starting: The engine cranks for an extended period before firing up, or it may crank without starting at all. This is often one of the first signs .
  2. Engine Stalling: The engine may stall unexpectedly, particularly at low speeds, when idling, or under heavy load .
  3. Loss of Power: You may notice a significant drop in power during acceleration, especially when going uphill or carrying weight .
  4. Whining Noise from the Tank: A failing pump often produces a loud whining or buzzing sound coming from the rear of the vehicle. This is the pump struggling to operate, and it's often more noticeable when the fuel level is low .
  5. Sputtering or Hesitation: The engine may sputter or hesitate during acceleration due to inconsistent fuel delivery .

It's important to note that these symptoms can also be caused by other issues, such as a clogged fuel filter, faulty fuel injectors, or ignition problems . A proper diagnosis is essential before you spend money on a new pump.

How to Test the Fuel Pump

Before condemning the pump, you should run a few basic tests to confirm it is the source of the problem.

Listen for the Prime: Turn the ignition key to the "ON" position without starting the engine. You should hear the fuel pump hum for about two to three seconds as it pressurizes the system. If you hear nothing, the pump may not be receiving power, or it has failed completely .

Check the Fuse and Relay: The fuel pump fuse and relay are located in the under-hood fuse box. Consult your owner's manual for the exact location. Use a multimeter to test the fuse for continuity. If the fuse is fine, swap the relay with a known-good relay of the same type. If the pump starts working, the relay was the issue .

Fuel Pressure Test: The most definitive test is measuring the fuel pressure. The 2009 Murano should deliver between 45-50 PSI at the fuel rail . Some sources indicate around 51 PSI . Connect a fuel pressure gauge to the test port on the fuel rail, turn the key to "ON," and compare the reading to spec. Low pressure indicates a weak pump, a clogged filter, or a faulty pressure regulator .

Step-by-Step: Accessing the Fuel Pump

If you've confirmed the pump is faulty, here is how to access and remove it. This job takes about 2 to 4 hours for a DIYer .

Safety First: Work in a well-ventilated area. Disconnect the negative battery cable. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls, or by using the Schrader valve on the fuel rail .

Tools You'll Need:

  • Socket wrench set
  • Screwdriver set
  • Fuel line disconnect tool
  • Multimeter
  • Fuel pressure gauge (for testing)
  • Shop rags

The Process:

  1. Remove the Rear Seat: Locate the retaining bolts or clips on the rear seat bottom cushion. Remove them, then lift the cushion up and out of the way to expose the floor pan .
  2. Locate the Access Panel: You'll see a metal access cover on the floor. Remove the screws or bolts holding it in place and set it aside .
  3. Disconnect the Electrical Connector: You'll now see the top of the fuel pump module. Disconnect the wire harness from the top of the module.
  4. Disconnect the Fuel Lines: Using a fuel line disconnect tool, press the release tabs and pull the fuel supply and return lines straight off the module. Be prepared for residual fuel to spill—have rags ready .
  5. Remove the Locking Ring: The module is held in place by a large plastic retaining ring. Use a wrench and a flat-head screwdriver (or a special fuel pump lock ring tool) to turn the ring counterclockwise and loosen it. Once loose, lift the ring off .
  6. Lift Out the Module: Carefully lift the entire fuel pump module out of the tank. You may need to tilt it slightly to clear the tank opening. The module includes the pump, the sending unit, and the float .
  7. Install the New Pump: Transfer any reusable components (like the rubber gasket) to the new module. Place the new module into the tank, being careful not to damage the float. Reinstall the locking ring, reconnect the hoses and electrical connector, and replace the access panel.
  8. Reinstall the Seat: Put the rear seat cushion back in place and secure it .

Fuel Pump Replacement Cost and Parts

The cost to replace the fuel pump on a 2009 Murano varies depending on whether you do it yourself or hire a mechanic. The part itself typically costs between $100 and $300 for a quality aftermarket unit or OEM replacement. The OEM part number for the Murano fuel pump module is 17040-1AA0C . Labor costs, if you have a shop do it, can add another $200 to $400, bringing the total to anywhere from $300 to $600 .

When you replace the pump, it is highly recommended to replace the fuel filter as well if the Murano has an external one. Some models integrate the filter into the pump module, in which case it's automatically replaced . Running the tank low on fuel regularly can shorten the pump's lifespan, as the fuel is needed to cool the pump .
