2007 Nissan Murano Fuel Pump: Complete Guide to Symptoms, Replacement Cost, and Best Options
The bottom line: If you own a 2007 Nissan Murano with the 3.5L VQ35DE engine and you are experiencing hard starting, stalling, loss of power, or a whining noise from the fuel tank area, your fuel pump is likely failing. Replacing it typically costs between $400 and $1,000 at a shop, with parts ranging from $150 to $750 depending on whether you choose aftermarket or OEM components. The fuel pump is located inside the fuel tank and requires removing the rear seat for access. This guide covers everything you need to know about symptoms, diagnosis, replacement options, and how to save money while getting a reliable repair.
Understanding the Fuel Pump in Your 2007 Nissan Murano
The fuel pump in your 2007 Nissan Murano is an electric, in-tank unit that draws fuel from the tank and delivers it under pressure to the engine's fuel injectors. This pump is submerged in gasoline, which helps keep the electric motor cool during operation. The 3.5-liter VQ35DE engine requires a consistent fuel pressure of approximately 51 psi to run properly. When the pump starts to fail, it cannot maintain this pressure, leading to a variety of performance issues.
The complete fuel pump module includes the pump itself, a fuel level sending unit, a strainer or filter, and sometimes a pressure regulator. When you replace the pump, you typically replace the entire module assembly rather than just the pump motor. This is important because the sending unit and other components wear out over time too.
Common Symptoms of a Failing Fuel Pump
If your 2007 Murano is having fuel delivery problems, you will likely notice one or more of the following symptoms:
1. Hard starting or no start. A failing fuel pump may struggle to build enough pressure to start the engine. You might find yourself cranking the engine longer than usual before it fires up. In severe cases, the engine may crank but never start because no fuel is reaching the injectors.
2. Unexpected stalling. Inconsistent fuel delivery can cause the engine to stall while driving, especially during acceleration or when climbing hills. This happens because the pump cannot keep up with the fuel demand under load.
3. Loss of power and hesitation. When the fuel pressure drops, the engine feels sluggish. You may notice hesitation when pressing the accelerator pedal, particularly at highway speeds. The vehicle simply does not respond the way it should.
4. Whining noise from the fuel tank. A healthy fuel pump operates quietly. If you hear a buzzing, whining, or humming sound coming from the rear of the vehicle near the fuel tank, the pump bearings may be wearing out. This noise often gets worse when the fuel level is low.
5. Check engine light. The engine control module monitors fuel pressure and can set diagnostic trouble codes such as P0087 (fuel rail pressure too low) or P0230 (fuel pump primary circuit malfunction). If your check engine light comes on, it is worth scanning for codes.
How to Diagnose a Bad Fuel Pump
Before you spend money on a new pump, you can perform some basic checks at home. These steps can help confirm whether the fuel pump is actually the problem.
Listen for the priming sound. When you turn the ignition key to the ON position without starting the engine, the fuel pump should run for about two to three seconds to build pressure. You should hear a brief buzzing sound from the rear of the vehicle. If you hear nothing, the pump may not be receiving power or it may be dead.
Check the fuel pump fuse and relay. Locate the fuel pump fuse in the engine compartment fuse box. Use a test light or multimeter to check for voltage on both sides of the fuse. If the fuse is blown, replace it and see if it blows again. A blown fuse can indicate a short circuit in the pump wiring. The fuel pump relay can also fail. You can swap it with a known good relay of the same type to test it.
Measure fuel pressure. This is the most reliable way to diagnose a weak pump. You will need a fuel pressure gauge that connects to the fuel rail. The 2007 Murano should maintain around 51 psi. If the pressure is significantly lower, the pump is likely failing. If the pressure is normal but the pump is noisy, it may still be on its way out.
Check for voltage at the pump connector. If you have access to the pump wiring after removing the rear seat, you can use a multimeter to check for power when the ignition is turned on. No voltage means the issue is in the electrical circuit rather than the pump itself.
How Much Does a Replacement Cost?
The total cost to replace the fuel pump on a 2007 Nissan Murano depends on several factors, including parts quality, labor rates in your area, and whether you use a dealership or an independent shop.
Parts cost. Aftermarket fuel pump modules typically range from $150 to $450. OEM Nissan parts cost between $350 and $750. For example, the genuine Nissan part number 17040-CA000 fits 2003-2007 Murano models and retails for around $428 to $654 depending on the seller. Another OEM option, part number 17040-1AA0A, fits 2008-2010 models and costs about $428.
Labor cost. Replacing the fuel pump takes about two to four hours, depending on the shop's experience and whether the tank requires extra work. Shop rates range from $75 to $150 per hour, so labor typically runs between $150 and $600.
Additional costs. You may need to pay for taxes, disposal fees for the old pump, and potentially replacement of fuel hoses or the fuel filter. These extras can add $50 to $200 to the total bill.
Total estimate. For a 2007 Murano, expect to pay between $400 and $1,000 for a professional replacement. Dealerships will be at the higher end, while independent shops often offer lower rates. Some online estimates show a shop/dealer price range of $628 to $879 for similar model years.
Where to Buy a Replacement Fuel Pump
You have several options for purchasing a new fuel pump, each with different trade-offs in price and quality.
Nissan dealership. This is the most expensive option, but you get genuine OEM parts and factory-backed labor. Dealers will install the correct part for your specific VIN and trim level. Expect to pay premium prices.
Independent auto shop. Many independent shops can source quality aftermarket parts or OEM-equivalent components at lower prices than dealerships. They can also provide an itemized estimate so you know exactly what you are paying for.
Online retailers and auto parts stores. You can buy a fuel pump module online from retailers like Summit Racing, RockAuto, or NissanPartsDeal. For example, a Beck/Arnley aftermarket pump for 2003-2014 Murano models costs about $282 and includes a sending unit and strainer. Just make sure to verify compatibility with your vehicle's VIN before ordering.
DIY replacement. If you are mechanically inclined, you can replace the pump yourself and save the labor cost. The job requires removing the rear seat, accessing the pump through an access panel, and carefully handling fuel system components. This is not a difficult job for an experienced DIYer, but you must follow safety precautions to avoid fire hazards.
Step-by-Step Overview of the Replacement Process
If you decide to tackle this job yourself, here is a general outline of what is involved. Always consult your vehicle's service manual for torque specifications and safety procedures.
Step 1: Relieve fuel system pressure. Locate the fuel pump fuse or relay and remove it. Start the engine and let it run until it stalls. This relieves pressure in the fuel lines.
Step 2: Disconnect the battery. Remove the negative battery cable to prevent any electrical sparks while working near fuel.
Step 3: Remove the rear seat. The fuel pump access panel is located under the rear seat cushion. Remove the seat by unscrewing the securing bolts.
Step 4: Access the pump. Remove the access panel cover. You will see the fuel pump module with electrical connectors and fuel lines attached. Carefully disconnect the electrical connector and the fuel lines. Have a rag ready to catch any residual fuel.
Step 5: Remove the pump assembly. Use a special tool or a hammer and punch to loosen the locking ring that holds the pump module in place. Turn the ring counterclockwise and lift the assembly out of the tank.
Step 6: Install the new pump. Transfer any reusable brackets or seals from the old pump to the new one. Insert the new pump assembly into the tank and secure it with the locking ring turned clockwise. Reconnect the fuel lines and electrical connector.
Step 7: Reassemble and test. Reinstall the access panel and rear seat. Reconnect the battery. Turn the ignition to the ON position several times to prime the fuel system. Check for leaks before starting the engine.

Tips to Save Money on Your Fuel Pump Replacement
Replacing a fuel pump is not cheap, but there are ways to reduce the overall cost without sacrificing quality.
Get multiple quotes. Contact at least three different shops in your area and ask for itemized estimates. Compare parts costs, labor rates, and any additional fees. Independent shops are often significantly cheaper than dealerships.
Consider aftermarket parts. While OEM parts are generally reliable, reputable aftermarket brands like Beck/Arnley and KEMSO offer excellent alternatives at lower prices. Just make sure the part includes the sending unit and pressure regulator if your vehicle requires them.
Replace the fuel filter at the same time. Even if your vehicle has a filter built into the pump module, an external inline filter should be replaced during the job. A clogged filter can strain your new pump and reduce its lifespan.
Check for recalls or extended warranties. Nissan has issued some service campaigns related to fuel system components over the years. Contact a dealership with your VIN to see if any coverage applies to your vehicle.
Do the labor yourself. If you have basic mechanical skills and the right tools, replacing the fuel pump is a manageable DIY job. The savings on labor can be substantial.
