2007 Nissan Murano Fuel Pump Relay Location: A Complete Guide for Owners

The bottom line up front: The fuel pump relay on a 2007 Nissan Murano is located in the engine bay fuse box, which sits on the driver's side near the battery. It is the relay labeled "Fuel Pump" or marked with a fuel pump icon on the fuse box cover diagram. If your Murano cranks but won't start, or starts and dies after a few seconds, the fuel pump relay is one of the first things you should check.

What Does the Fuel Pump Relay Do?

Before you go hunting for the relay, it helps to understand its job. The fuel pump relay is an electrical switch that controls power to the fuel pump. When you turn the key to the "ON" position, the relay closes and sends battery voltage to the fuel pump so it can pressurize the fuel system. Once the engine is running, the relay keeps the pump powered.

A bad relay can cause a variety of problems, many of which mimic a failing fuel pump itself. That is why knowing the location and how to test the relay is so important—it saves you from replacing an expensive fuel pump when the real problem is a $20 relay.

Exact Location of the Fuel Pump Relay on a 2007 Nissan Murano

The 2007 Nissan Murano has two fuse boxes: one inside the cabin and one under the hood. The fuel pump relay is in the under-hood fuse box, also called the IPDM (Intelligent Power Distribution Module) on some models.

Here is how to find it:

  1. Open the hood and look toward the driver's side. The fuse box is a black plastic rectangular box near the battery.
  2. Press the tab on the side of the fuse box cover and lift it off.
  3. Look at the diagram printed on the inside of the cover. You will see a labeled square that says "Fuel Pump" or shows a fuel pump symbol. That is the relay.
  4. Pull the relay straight out. It is a small black or blue cube with four or five prongs on the bottom.

On some Murano models, the relay is not labeled explicitly but is identified by its position in the fuse box. If you are unsure, check your owner's manual or look for the fuse box diagram online specific to your trim level.

Common Symptoms of a Bad Fuel Pump Relay

A failing fuel pump relay can cause several noticeable problems. Here are the most common signs to watch for:

  1. Engine cranks but will not start. This is the most classic symptom. You turn the key, the starter spins the engine, but it never fires up because the fuel pump is not getting power.
  2. Engine starts then dies. The relay may work initially but fail once the engine is running, cutting power to the fuel pump and killing the engine.
  3. No fuel pump priming sound. When you turn the key to the "ON" position (without cranking), you should hear a faint whirring sound from the rear of the vehicle for about 2 seconds. If you hear nothing, the relay or pump may be bad.
  4. Intermittent stalling. The vehicle may run fine for a while, then suddenly stall. After a few minutes, it may start again. This points to an overheating or failing relay.
  5. Engine sputters under load. If the relay is weak, it may not deliver consistent voltage, causing the engine to hesitate or sputter during acceleration.

Keep in mind that these symptoms can also be caused by a bad fuel pump itself, a clogged fuel filter, or a faulty fuel pump fuse. Always test the relay before condemning the pump.

How to Test the Fuel Pump Relay

Testing the fuel pump relay is simple and takes about 10 minutes. You will need either a multimeter or a test light. Here is the step-by-step process:

  1. Remove the relay from the fuse box as described above.
  2. Set your multimeter to measure resistance (ohms).
  3. Check the coil side. The relay has two pins for the coil (usually the smaller pins). Measure resistance across them. You should see a reading between 50 and 120 ohms. If you get infinite resistance, the coil is open and the relay is dead.
  4. Apply power to the coil. Use a 12V battery or jump pack to energize the coil pins.
  5. Check the switch side. With the coil energized, measure continuity across the two larger pins. You should hear a click and see near-zero resistance. If you do not hear a click, the relay is faulty.

Alternatively, you can do a simple swap test: take the relay out, find another relay of the same part number in the fuse box (like the horn or headlight relay), and swap them. If the engine starts, your relay is bad.

How to Replace the Fuel Pump Relay

Replacing the fuel pump relay on a 2007 Nissan Murano is one of the easiest repairs you can do yourself. Here is what you need to do:

  1. Turn off the engine and remove the key from the ignition.
  2. Open the hood and locate the under-hood fuse box.
  3. Pull the old relay straight out with your fingers or a small pair of pliers.
  4. Compare the new relay to make sure the part number and pin layout match.
  5. Push the new relay firmly into the same socket until it clicks into place.
  6. Replace the fuse box cover and close the hood.

The whole process should take less than five minutes. No tools are required beyond your hands, though pliers can help if the relay is stuck.

The cost of a new fuel pump relay for a 2007 Murano is typically between $15 and $40 depending on whether you buy OEM or aftermarket. This is far cheaper than replacing a fuel pump, which can cost anywhere from $400 to $800 including labor.

Fuel Pump Relay vs. Fuel Pump: How to Tell the Difference

Many Murano owners assume a no-start condition means the fuel pump itself is dead. But the relay is far more common to fail because it is an electrical component that cycles every time you start the car.

Here is a quick way to narrow down the problem:

  • Check for power at the pump. The fuel pump on the 2007 Murano is inside the fuel tank. You can access the electrical connector under the rear seat or from underneath the vehicle.
  • Use a test light to check for power at the pump connector while someone turns the key to "ON." If there is no power, the problem is likely the relay, fuse, or wiring. If there is power but no pump noise, the pump itself is bad.
  • Check the fuse first. The fuel pump fuse is usually in the same fuse box as the relay. A blown fuse is even easier to fix than a relay.

Remember: the relay controls power to the pump. If the relay fails, the pump never gets power. Testing in this order saves you time and money.

Common Causes of Relay Failure

Fuel pump relays do not last forever. Here are the most common reasons they fail:

  1. Normal wear and tear. Relays have mechanical contacts inside that arc and wear out over time. After years of use, the contacts can become pitted or corroded.
  2. Heat exposure. The engine bay gets hot, especially on the driver's side near the battery. Excessive heat can degrade the relay's internal components.
  3. Voltage spikes. Electrical surges from the battery or alternator can damage the relay's coil.
  4. Moisture and corrosion. If water gets into the fuse box, it can corrode the relay terminals and cause intermittent failures.

The good news is that relay failure is usually gradual. You may notice intermittent starting problems for days or weeks before the relay fails completely.

Why You Should Consider a Quality Replacement Pump

If you have confirmed that your fuel pump itself is failing (not just the relay), choosing the right replacement matters. A low-quality pump can fail quickly, leaving you stranded and paying for labor twice.

Preventative Maintenance Tips

To avoid fuel pump and relay problems in the future, follow these simple tips:

  1. Keep your fuel tank above a quarter tank. Running low on fuel regularly can cause the pump to overheat because fuel acts as a coolant.
  2. Replace your fuel filter on schedule. A clogged fuel filter makes the pump work harder, which shortens its lifespan.
  3. Check your fuse box for moisture. If you live in a humid area or drive through deep water, inspect the fuse box for signs of corrosion.
  4. Listen for the prime. Every time you start your Murano, listen for the fuel pump hum. If it gets louder or quieter than usual, investigate early.

Final Thoughts

The 2007 Nissan Murano fuel pump relay is easy to find and even easier to replace. It lives in the under-hood fuse box on the driver's side, right next to the battery. If your Murano cranks but will not start, testing and replacing this relay should be your first move—it costs less than $40 and takes five minutes.

If you have already replaced the relay and the problem persists, move on to testing the fuel pump itself. And if the pump needs to be replaced, choose a quality part like a KEMSO fuel pump.
