2006 Nissan Murano Fuel Pump: Symptoms, Location, and Replacement Guide
If your 2006 Nissan Murano is hard to start, stalls while driving, or you hear a whining noise coming from the rear of the vehicle, the fuel pump is the most likely culprit. The fuel pump in your Murano is located inside the fuel tank, and replacing it is a straightforward job if you have the right information. This guide covers everything you need to know about the 2006 Nissan Murano fuel pump, including symptoms of failure, where to find it, how to replace it, and what replacement pump to choose.
Symptoms of a Failing Fuel Pump in Your 2006 Nissan Murano
A failing fuel pump rarely fails without warning. Here are the most common signs that your Murano's fuel pump is going bad:
1. Hard Starting
When the fuel pump cannot build enough pressure, the engine cranks longer than normal before starting. You may need to cycle the key several times to get the engine to fire. This is often the first noticeable symptom.
2. Engine Stalling
A failing pump can cause the engine to stall unexpectedly, especially during low-speed driving or when the fuel tank is low. This happens because the pump cannot maintain consistent fuel pressure to the engine.
3. Sputtering at High Speeds
If you feel a loss of power or sputtering when accelerating on the highway, the fuel pump may not be delivering enough fuel to meet the engine's demand. This is a sign that the pump is wearing out.
4. Whining Noise from the Fuel Tank
A healthy fuel pump runs quietly. If you hear a loud, high-pitched whining sound coming from the rear of the vehicle (near the fuel tank), the pump is likely failing. The noise means the pump motor is working harder than it should.
5. Check Engine Light
The check engine light may come on with diagnostic trouble codes related to fuel pressure or fuel system performance. Common codes include P0087 (fuel rail pressure too low) or P0191 (fuel pressure sensor range/performance).
Where Is the Fuel Pump Located on a 2006 Nissan Murano?
The fuel pump on the 2006 Nissan Murano is located inside the fuel tank. The fuel tank sits under the rear of the vehicle, behind the rear seats. The pump is accessed through a service panel that is located under the rear seat cushion on the passenger side.
To access the fuel pump, you need to remove the rear seat cushion and then lift the metal access panel. The pump module is a complete assembly that includes the fuel pump, fuel level sending unit, and fuel filter.
How to Replace the Fuel Pump on a 2006 Nissan Murano
Replacing the fuel pump on your 2006 Nissan Murano is a doable job for a DIY mechanic with basic tools. The entire process takes about 1 to 2 hours. Here is a step-by-step guide:
Step 1: Relieve Fuel System Pressure
Before you start, remove the fuel pump fuse from the fuse box located under the dashboard on the driver's side. Then start the engine and let it run until it stalls. This releases the pressure in the fuel system. Disconnect the negative battery terminal for safety.
Step 2: Remove the Rear Seat
Fold the rear seat forward. Locate the two bolts at the front of the seat cushion and remove them. Lift the seat cushion up and out of the vehicle.
Step 3: Access the Fuel Pump
You will see a metal access panel on the floor of the vehicle, on the passenger side. Remove the screws or bolts that hold the panel in place. Lift the panel to reveal the top of the fuel pump module.
Step 4: Disconnect the Fuel Lines and Electrical Connector
Clean the area around the pump module to prevent dirt from falling into the tank. Disconnect the electrical harness connector. Use a fuel line disconnect tool to release the fuel lines. Be prepared for a small amount of fuel to spill.
Step 5: Remove the Old Pump Module
Use a locking ring removal tool or a hammer and punch to turn the locking ring counterclockwise. Lift the old pump module straight out of the tank. Be careful, as the module may still contain fuel.
Step 6: Install the New Pump Module
Transfer the rubber gasket to the new pump module (if not already installed). Lower the new module into the tank, making sure the float arm is not bent and the strainer is not touching the bottom of the tank. Replace the locking ring and tighten it clockwise.
Step 7: Reconnect Everything
Reconnect the fuel lines and electrical connector. Replace the access panel and secure it with screws. Reinstall the rear seat cushion and tighten the bolts.
Step 8: Test the System
Reconnect the battery and install the fuel pump fuse. Turn the key to the ON position (without starting) for 2 seconds, then OFF. Repeat this 3 times to prime the fuel system. Start the engine and check for leaks.

How to Make Your New Fuel Pump Last Longer
Once you replace the fuel pump on your 2006 Nissan Murano, follow these simple rules to maximize its lifespan:
Keep your tank above a quarter full. This is the single most important thing you can do. The fuel in the tank keeps the pump cool and lubricates the internal components. Running the tank low regularly causes the pump to run hotter and can shorten its life. Make it a habit to refill when the gauge hits a quarter tank.
Change your fuel filter regularly. The fuel filter is part of the pump module assembly. Even though you replaced it with the pump, it is still a good idea to replace the fuel filter at the recommended interval, which is typically every 30,000 to 60,000 miles. A clean filter reduces strain on the pump.
Use quality fuel from reputable stations. Not all gas stations are the same. Busy stations with high turnover are less likely to have old or contaminated fuel. Avoid stations that look old and poorly maintained. Contaminated fuel can damage the pump and the fuel injectors.
Address check engine lights promptly. If your check engine light comes on, do not ignore it. Even if the car seems to drive fine, the computer may have detected a fuel pressure issue that you cannot feel yet.
Final Thoughts
The fuel pump on your 2006 Nissan Murano is a critical component that keeps your engine running. If you are experiencing hard starting, stalling, or a whining noise from the fuel tank area, do not wait.
