2006 Honda CRV Fuel Pump Relay Location: A Complete Owner's Guide
If you drive a 2006 Honda CR-V and suspect a fuel delivery problem, the fuel pump relay is one of the first components you should check. The fuel pump relay on a 2006 Honda CR-V is located in the under-hood fuse box, positioned on the driver's side of the engine bay near the battery. This relay controls power to the electric fuel pump, which sits inside the fuel tank and delivers gasoline to the engine. When the relay fails, the pump receives no power, and your engine will crank but refuse to start. Knowing exactly where to find this relay and how to test it can save you time, money, and a tow truck bill.
Why the Fuel Pump Relay Matters
The fuel pump relay acts as a switch that sends battery power to the fuel pump when you turn the ignition key to the "ON" position. On the 2006 CR-V, the fuel pump is an in-tank electric unit that pressurizes the fuel system for about three to four seconds when you first turn the key, then continues running while the engine operates. If the relay fails, the pump never receives power, and the engine will not start even though the battery is strong and the starter motor turns normally.
A failing relay can also cause intermittent problems. You might experience hard starting, engine stalling, or a no-start condition that comes and goes. These symptoms can be frustrating because they mimic other issues like a bad fuel pump or a clogged fuel filter. That is why testing the relay before replacing expensive parts is a smart diagnostic step.
Locating the Fuel Pump Relay on Your 2006 CR-V
The under-hood fuse box on the 2006 Honda CR-V is a black plastic box located on the driver's side of the engine compartment, near the battery and the fender. To access the fuel pump relay, follow these steps:
1. Open the hood and secure it with the prop rod.
2. Look for the main fuse box. On the 2006 CR-V, it sits close to the battery, typically on the driver's side. The box has a removable lid with a diagram printed on the underside.
3. Remove the fuse box cover. Press the release tabs on the sides of the cover and lift it straight up. Turn the cover over and inspect the diagram. You will see a list of relays and fuses with their positions labeled.
4. Identify the fuel pump relay. On the 2006 CR-V, the fuel pump relay is usually labeled "Fuel Pump" or abbreviated as "FUEL PUMP" on the diagram. It is a small, square component with four or five prongs that plugs into the fuse box. In most cases, it is located in the same row as other relays, often near the center or toward the rear of the fuse box.
5. Compare the relay to others. If the labeling is unclear, compare the suspect relay to others in the box. All relays of the same type look identical. If you have a spare relay with the same part number and pin configuration, you can swap them for testing purposes.
If your under-hood diagram is missing or worn, consult your owner's manual or search online for the specific fuse box layout for the 2006 CR-V. Some owners also find the relay location listed on forums and repair sites, where experienced DIYers share diagrams and photos.
How to Test the Fuel Pump Relay
Before you order a new relay, test the one already in your vehicle. A simple test can confirm whether the relay is the culprit or whether the problem lies elsewhere, such as the fuel pump itself, the fuel pump fuse, or the wiring.
Step 1: Locate the relay and remove it. With the ignition off, grasp the relay firmly and pull it straight out of the fuse box socket.
Step 2: Inspect the relay visually. Look for signs of corrosion, burnt marks, or melted plastic. Any of these indicate a failed relay.
Step 3: Test the relay with a multimeter. Set your multimeter to measure resistance (ohms). Identify the relay's coil terminals, usually pins 85 and 86, and the switch terminals, usually pins 30 and 87. Apply 12 volts from a battery or power supply to pins 85 and 86. You should hear a click, and the resistance between pins 30 and 87 should drop to near zero when the relay is energized. If you do not hear a click or the resistance does not change, the relay is defective.
Step 4: Swap the relay with a known-good one. If you have another relay with the same part number and pin layout, swap them. If the engine starts with the replacement relay, your original relay is bad.
Testing the relay is a quick procedure that takes about ten minutes and requires minimal tools. A multimeter costs around twenty dollars at any auto parts store, making this a low-cost diagnostic step.
What to Do If the Relay Is Not the Problem
If the relay tests good and the engine still will not start, move on to other components in the fuel delivery system. On the 2006 CR-V, the fuel filter is not a separate serviceable part; it is built into the fuel pump module inside the fuel tank. That means you cannot replace an inline filter to fix a clogged system. Instead, you must address the pump module itself.
Check the fuel pump fuse. The fuse box diagram will show the fuse that protects the fuel pump circuit. A blown fuse will cut power to the pump just like a failed relay. Replace the fuse with one of the same amperage rating.
Listen for the fuel pump prime. Turn the ignition key to the "ON" position without cranking the engine. You should hear a faint whirring sound coming from the rear of the vehicle for two or three seconds. This is the fuel pump pressurizing the system. If you hear nothing, the pump may not be receiving power, or the pump itself may be dead.
Check the fuel pump electrical connector. On the 2006 CR-V, the fuel pump assembly is accessible through an access panel under the left rear seat. Open the left rear door, fold the rear seat forward, and lift the carpet to find a circular metal cover. Remove the cover with a screwdriver to access the fuel pump module and its electrical connector. Ensure the connector is firmly seated and free of corrosion.
Check fuel pressure. If the pump is running but the engine still will not start, you may have a pressure problem. A mechanic can test fuel pressure with a gauge to confirm the pump is delivering the correct amount of fuel. Low pressure can indicate a weak pump, a clogged strainer, or a faulty pressure regulator.
Consider the fuel pump itself. If the pump makes a loud whining noise, fails to prime, or produces low pressure, the pump module likely needs replacement. On the 2006 CR-V, replacing the fuel pump does not require dropping the fuel tank. You can access it through the opening under the left rear seat by removing the cover and the pump lock ring.
Common Symptoms of a Failing Fuel Pump Relay
Recognizing the warning signs of a failing relay can help you address the problem before it leaves you stranded. Common symptoms include:
1. Engine cranks but does not start. This is the most common symptom of a failed fuel pump relay. The starter motor turns the engine, but the fuel pump receives no power, so no fuel reaches the injectors.
2. Intermittent starting issues. A relay that is failing but not completely dead may work sometimes and fail at other times. You might find that the car starts fine cold but refuses to start after the engine warms up.
3. Engine stalls while driving. If the relay loses contact while the engine is running, the fuel pump will stop, and the engine will stall abruptly. This is a safety hazard, especially at highway speeds.
4. No fuel pump prime sound. When you turn the key to the "ON" position, you should hear the fuel pump hum for a few seconds. If you hear nothing, the relay is not sending power to the pump.
5. Check engine light illuminates. A failing fuel pump or relay can cause a lean fuel condition, which may trigger a diagnostic trouble code and turn on the check engine light. Common codes include P0087, which indicates low fuel rail pressure.
If you experience any of these symptoms, start by checking the relay. It is a cheap, easy fix that can save you from replacing a costly fuel pump unnecessarily.

Step-by-Step Fuel Pump Replacement Overview
If you have confirmed that the fuel pump needs replacement, you can save hundreds of dollars by doing the job yourself. A professional replacement on a CR-V typically costs between $1,153 and $1,228, with parts alone ranging from $1,023 to $1,038. A DIY replacement costs anywhere from $180 to $650 depending on the pump you choose. On the 2006 CR-V, the job is manageable for an intermediate DIYer because you do not need to drop the fuel tank.
Step 1: Relieve fuel system pressure. Remove the fuel pump fuse from the under-hood fuse box. Start the engine and let it run until it stalls. Crank the engine for three to four more seconds to release any remaining pressure. Turn the ignition off and reinstall the fuse.
Step 2: Disconnect the battery. Use a 10mm socket to disconnect the negative battery cable and move it away from the terminal to prevent accidental contact.
Step 3: Access the fuel pump. Fold the left rear seat forward. Lift the carpet to expose the access cover. Use a screwdriver to remove the cover and reveal the fuel pump module.
Step 4: Disconnect the fuel lines and electrical connector. Unplug the pump's electrical connection and the fuel supply line. Have a shop towel ready to catch any excess fuel.
Step 5: Remove the pump lock ring. Use the special tool (Honda part number 07AAA-S0XA100) to turn the lock ring counterclockwise until it releases. Lift the pump module out of the tank.
Step 6: Install the new pump. Transfer any necessary components from the old module to the new pump, if you are replacing only the pump element. Install the new pump, replace the O-ring and gasket, and tighten the lock ring to 69 foot-pounds with a torque wrench.
Step 7: Reconnect everything and test. Reconnect the fuel lines and electrical connector. Reinstall the access cover and seat. Reconnect the battery and turn the key to the "ON" position. Listen for the fuel pump prime, then start the engine and check for leaks.
Safety is the top priority when working with gasoline. Work in a well-ventilated area, keep a fire extinguisher nearby, and avoid smoking or using open flames. If you are not comfortable with any step, have a professional handle the job.
Preventing Future Fuel Pump Problems
The best way to avoid fuel pump failure is to take care of the system. Here are a few habits that will extend the life of your fuel pump:
Keep your fuel tank at least a quarter full. The fuel pump relies on gasoline to stay cool. Running the tank low regularly causes the pump to work harder and overheat, shortening its lifespan.
Replace your fuel filter on schedule. Although the 2006 CR-V does not have a separate external filter, the strainer inside the tank can become clogged over time. Replacing the pump module includes a new strainer, which restores proper fuel flow.
Address fuel system issues promptly. If you notice hard starting, hesitation, or a whining noise from the rear of the vehicle, diagnose the problem early. Catching a failing pump or relay before it fails completely can prevent a roadside breakdown.
Use quality fuel. Dirty or contaminated fuel can clog the strainer and damage the pump. Buy fuel from reputable stations that maintain their tanks.
Final Thoughts
Finding the fuel pump relay on a 2006 Honda CR-V is a straightforward process. The relay lives in the under-hood fuse box on the driver's side, and testing it takes minutes. If the relay is good but the pump is failing, replacing the pump module through the access panel under the left rear seat is a manageable DIY job that can save you significant money.
