2009 Nissan Murano Fuel Pump Replacement: A Complete Owner’s Guide

The bottom line up front: If your 2009 Nissan Murano is hard to start, sputters during acceleration, stalls at idle, or makes a whining noise coming from the fuel tank area, the fuel pump is likely failing. Replacing it is a job you can do yourself with basic tools, a few hours of time, and the right replacement part. This guide walks you through every step—from confirming the diagnosis to installing a new pump—so you can get back on the road with confidence.

The 2009 Murano uses a single in-tank electric fuel pump that sits inside the fuel tank, accessible through an access panel under the rear seat. It delivers fuel from the tank to the engine at a regulated pressure of roughly 45–51 psi. When the pump wears out—typically after 100,000–150,000 miles—you will notice performance problems that only get worse over time.

How to Tell If Your Fuel Pump Is Going Bad

A failing fuel pump does not die all at once. It gives you warning signs first. Recognizing these early can save you from being stranded.

Common symptoms of a failing fuel pump on a 2009 Murano include:

  1. Difficulty starting. The engine cranks for a long time before firing up, or it may not start at all, especially when the tank is low.
  2. Stalling. The engine dies unexpectedly, often at low speeds or while idling. In some cases it restarts after a few minutes.
  3. Loss of power. Acceleration feels weak, especially going uphill or carrying a load.
  4. Sputtering or hesitation. The engine stumbles or hesitates during acceleration due to inconsistent fuel delivery.
  5. Whining noise from the fuel tank. A failing pump often makes a loud, high-pitched hum, particularly when the tank is low.
  6. Rough idle. The engine idles unevenly or vibrates more than usual.
  7. Poor fuel economy. A pump that is struggling to maintain pressure makes the engine work harder, burning more gas.

These symptoms can also point to other issues, such as a clogged fuel filter or faulty fuel injectors. That is why proper diagnosis matters before you spend money on parts.

First, Rule Out the Simple Stuff

Before you drop the fuel tank or pull the rear seat, run through a few quick checks. These take minutes and can save you from unnecessary work.

Check the fuel pump fuse and relay. The fuel pump relay sits in the under-hood fuse/relay box. The fuse is usually labeled “Fuel Pump” in the fuse box. Use a multimeter to test the fuse for continuity. If the fuse is good, swap the relay with a known good one of the same type. If the problem goes away, you have found the culprit.

Listen for the fuel pump prime. Turn the ignition key to the “ON” position without starting the engine. You should hear a humming sound from the rear of the vehicle for a few seconds—that is the pump pressurizing the system. If you hear nothing, the pump may be dead, or power is not reaching it.

Check the fuel pressure. This is the most definitive test. Connect a fuel pressure gauge to the test port on the fuel rail (it looks like a tire valve stem). Turn the ignition to “ON” and note the reading. For the 2009 Murano, you want to see about 45–51 psi. Low pressure points to a failing pump, a clogged filter, or a faulty pressure regulator.

Inspect the fuel filter. A clogged filter restricts fuel flow and puts extra strain on the pump. In the 2009 Murano, the filter is integrated with the fuel pump module inside the tank. Replacing it means replacing the pump assembly—another reason to confirm the pump itself is the problem.

Locating the Fuel Pump on a 2009 Murano

The fuel pump on your Murano sits inside the fuel tank, which is located under the rear seat. That is good news—you do not need to drop the entire fuel tank just to reach the pump.

Here is what you need to know about access:

  • Remove the rear seat bottom. You will find retaining bolts or clips along the edges or underside of the seat cushion. Use a socket wrench or screwdriver to remove them, then lift the seat up and out.
  • Look for the access panel. Once the seat is out, you will see a metal or plastic cover panel. It is often marked or labeled for easy identification.
  • Remove the panel. Take out the screws or bolts holding it in place, then lift it off to expose the fuel pump module.

Work in a well-lit area. The seat removal process is straightforward, but you want to be careful not to force anything or damage interior clips.

Safety First: Preparing for Fuel Pump Work

Working on a fuel system involves gasoline, which is flammable. Take these precautions seriously before you start.

  1. Disconnect the battery. Remove the negative terminal cable before doing any fuel system work.
  2. Relieve fuel system pressure. Locate the Schrader valve on the fuel rail—the same port you use for a pressure gauge. Place a rag over it and press the valve in with a small screwdriver to release pressure.
  3. Work in a well-ventilated area. Gasoline vapors are hazardous. Open a garage door or work outside if possible.
  4. Have a fire extinguisher nearby. It is better to have one and not need it than to need one and not have it.
  5. Avoid sparks and open flames. Do not smoke, and keep any electrical devices or power tools away from the work area.

Tools and Parts You Will Need

Gather everything before you start. Running to the parts store mid-job is frustrating and wastes time.

Tools required:

  • Socket wrench set with extensions
  • Screwdrivers (flat-head and Phillips)
  • Multimeter (for electrical tests)
  • Fuel pressure gauge
  • Fuel line disconnect tool (for quick-connect fittings)
  • Shop rags
  • Safety glasses and gloves

Parts you will need:

  • A replacement fuel pump module (see the section below on choosing the right part)
  • New fuel line seals or O-rings (often included with the pump module)
  • New fuel filter (if not integrated into the pump assembly)
  • Battery terminal cleaner, if needed

Step-by-Step Fuel Pump Replacement

Once you have confirmed the fuel pump is bad, follow these steps. Expect to spend 2–4 hours if you are working at a comfortable pace.

Step 1: Disconnect the battery

Remove the negative battery cable. This prevents any accidental sparks or electrical shorts while you work.

Step 2: Relieve fuel system pressure

Remove the fuel cap to release tank pressure. Then locate the fuel rail test port and bleed off remaining pressure using the Schrader valve.

Step 3: Remove the rear seat and access panel

Follow the steps described earlier to remove the seat bottom and the fuel pump access cover.

Step 4: Disconnect electrical and fuel lines

You will see the fuel pump module secured by a plastic locking ring. Before removing anything:

  • Disconnect the electrical connector from the pump module.
  • Use a fuel line disconnect tool to release the fuel inlet and outlet hoses.
  • Label the hoses if needed so you reconnect them correctly.

Step 5: Remove the old pump module

Use a wrench to loosen the plastic locking ring. Turn it counterclockwise. Once loose, lift the entire pump module out of the tank.

Important: The pump module includes the electric pump, fuel level sending unit, and the fuel strainer. You will want to replace the entire assembly rather than just the pump motor. This is more reliable and saves you from doing the job twice.

Step 6: Install the new pump module

Transfer any reusable components from the old module to the new one, such as the rubber mounting grommet or O-ring. Then:

  • Lower the new module into the tank.
  • Seat it properly and tighten the locking ring clockwise until snug.
  • Reconnect the electrical connector.
  • Reattach the fuel lines using the disconnect tool, pushing until they click into place.

Step 7: Reinstall the access panel and seat

Put the access cover back on and secure it with the screws or bolts. Reinstall the rear seat bottom and tighten the retaining bolts.

Step 8: Reconnect the battery and test

Reconnect the negative battery cable. Turn the ignition to “ON” for a few seconds, then off. Repeat two or three times to prime the fuel system. Then start the engine and check for leaks around the fuel lines and pump module.

Choosing the Right Replacement Fuel Pump

You have two main options when buying a fuel pump for your 2009 Murano: OEM or aftermarket.

OEM (Original Equipment Manufacturer) parts are made by the same manufacturer that supplied the factory pump. For the 2009 Murano, the OEM part number is typically 17040-1AA0C, with earlier revisions 170401AA0A and 170401AA0B superseded by this version. OEM parts fit perfectly and perform exactly as the factory intended.

Aftermarket parts vary in quality. Some are excellent and may even outlast the OEM pump. Others are cheap and fail quickly. Read reviews and stick with reputable brands.

Whichever you choose, look for a complete fuel pump module assembly. This includes the pump, the level sending unit, the strainer, and the housing—everything you need in one box. Replacing just the pump motor is cheaper, but it leaves older components in place, and those may fail soon after.

Cost of Replacement

A fuel pump replacement on a 2009 Murano typically runs $300–$600 for parts and labor if you take it to a shop. The pump module itself usually costs between $150 and $350 depending on brand and whether you buy OEM or aftermarket.

Doing the job yourself cuts the labor cost entirely—you only pay for parts. That is a significant savings, and this job is very doable for someone with basic mechanical skill.

How Long Does a Fuel Pump Last?

A factory fuel pump on a 2009 Murano typically lasts 100,000–150,000 miles, depending on how the vehicle is driven and maintained. Several factors shorten pump life:

  • Running the tank low frequently. The pump relies on fuel for cooling and lubrication. Running on empty causes it to overheat and suck up sediment from the bottom of the tank.
  • Contaminated fuel. Dirt, rust, and debris clog the strainer and damage the pump mechanism.
  • Electrical issues. A faulty relay or voltage drop makes the pump work harder and run hotter.
  • Age and wear. Motor brushes wear out over time, reducing pump output.

To extend the life of a new pump:

  • Keep the gas tank at least a quarter full to keep the pump submerged and cool.
  • Use high-quality fuel from reputable stations.
  • Replace the fuel filter on schedule to keep contaminants out of the pump.
  • Address any fuel system trouble codes promptly. Diagnostic codes like P0087, P0088, and P0190–P0193 point to fuel pressure issues.

Related Components to Consider

While you are replacing the fuel pump, it is wise to think about the other parts of the fuel delivery system.

Fuel filter. On many vehicles, the fuel filter is a separate in-line unit. On the 2009 Murano, however, the filter is integrated into the fuel pump module inside the tank. When you replace the pump module, you are replacing the filter at the same time.

Fuel pressure regulator. In the Murano, the pressure regulator is also built into the pump assembly. Again, replacing the full module covers this.

Fuel lines and hoses. Inspect the fuel lines while you have access. Look for cracks, leaks, or worn connections. Replace any damaged lines. Replacing the fuel filter whenever the pump is replaced is recommended.

Common Questions About Murano Fuel Pump Replacement

How long does the replacement take?
Most fuel pump replacements take 2–4 hours. A professional mechanic can often do it in about 1–2 hours.

Can I drive with a failing fuel pump?
It is not safe. A failing pump can leave you stranded or cause engine damage. If you notice fuel leaks or the smell of gasoline, stop driving immediately and get the vehicle serviced.

Is it better to replace the pump or repair it?
Replacement is almost always the better choice. Repairing a pump is rarely reliable, and the labor cost is the same either way.

Does the 2009 Murano have two fuel pumps?
No. The 2009 Murano uses a single in-tank fuel pump. Some sources incorrectly claim a dual-pump system, but the standard configuration is one integrated pump module.

Will a new fuel pump improve fuel economy?
If the old pump was underperforming, yes. A new pump delivers the correct pressure consistently, which helps the engine run efficiently.

Final Thoughts

Replacing the fuel pump on a 2009 Nissan Murano is a manageable DIY project. The symptoms are easy to recognize, the diagnosis is straightforward, and the pump is accessible through the rear seat—no fuel tank removal required.

The key steps to remember:

  1. Confirm the pump is actually the problem using a fuel pressure test and listening for the prime sound.
  2. Take safety seriously. Disconnect the battery, relieve fuel pressure, and work in a well-ventilated area.
  3. Replace the complete pump module, not just the pump motor, to avoid repeat failures.
  4. Keep the tank at least a quarter full going forward to maximize the life of the new pump.
