Honda CRV Fuel Pump Relay Location: A Complete Guide to Finding and Replacing It

The Honda CRV fuel pump relay is most commonly located in the under-hood fuse/relay box on the driver's side of the engine compartment. For most models, including the 2001 CRV, it sits inside the black plastic fuse box near the battery. The relay is often labeled "FUEL PUMP," "FP," or "PGM-FI" on the fuse box lid diagram. If you open the hood and look for the main fuse box, pop the lid, and check the diagram printed on the underside, you'll likely spot it right away. This component controls the power supply to the fuel pump, and when it goes bad, your engine may crank but refuse to start. Knowing where to find it saves you time and money.

Understanding the Fuel Pump Relay’s Role

The fuel pump relay acts like a switch. When you turn your ignition key to the "ON" position, the relay sends power to the fuel pump so it can pressurize the fuel system. This allows the engine to get the fuel it needs to start and run. Over time, the relay can wear out due to heat, vibration, or electrical issues. A faulty relay often means no fuel pressure, and your CRV won't start even though the battery and starter are fine.

Common symptoms of a bad fuel pump relay include:

  • The engine cranks but does not start
  • No sound from the fuel pump when you turn the key to "ON"
  • Intermittent stalling while driving
  • Loss of power during acceleration

Where to Find the Fuel Pump Relay in Your Honda CRV

Under-Hood Fuse Box (Most Common Location)

For the vast majority of Honda CRVs, including the 2001 model, the fuel pump relay lives in the under-hood fuse/relay box . This box is located on the driver's side of the engine bay, near the battery. It is a black plastic box with a removable lid. The lid usually has a diagram on its underside that shows the position of each relay and fuse. Look for labels like "FUEL PUMP," "FP," "F/PUMP," or "PGM-FI Main" .

How to access it:

  1. Open the hood and locate the fuse box (driver's side, near the firewall).
  2. Press the tabs or clips to remove the lid.
  3. Check the diagram on the lid for the exact relay position.
  4. The relay is a small plastic cube, about 2 inches square, with prongs on the bottom.

Interior Fuse Box (Alternative Location for Some Models)

Some Honda CRV models, especially older ones or certain trims, place the fuel pump relay in the interior fuse box under the dashboard. For example, some sources indicate that for older CRVs, the relay can be found behind the driver's side kick panel or near the glove box . If you don't find it under the hood, check the interior fuse box.

Common interior locations:

  • Behind the driver's side kick panel (left of the steering wheel)
  • Near the glove box on the passenger side
  • Under the dashboard, close to the fuse panel

Generation-Specific Notes

1997-2001 CRV (First Generation): The PGM-FI main relay is located on the passenger's side behind the dashboard and glove box . This relay actually contains two relays in one unit—one for the fuel injectors and one for the fuel pump. The under-hood fuse box also contains a separate fuel pump relay for many models .

2002-2006 CRV (Second Generation): The fuel pump relay is in the under-hood fuse/relay box on the driver's side .

2007-2011 CRV (Third Generation): Same location—under-hood relay box, labeled "FUEL PUMP" or "FP" .

2012-2016 CRV (Fourth Generation): Also in the under-hood fuse box; refer to the lid diagram .

2017-2022 CRV (Fifth Generation): The fuel pump relay remains in the under-hood fuse box .

How to Test the Fuel Pump Relay

Before buying a new relay, you can test it to confirm it's faulty. Here are three simple methods:

1. The Swap Test: Find a relay in the same fuse box that is the same size and shape (like the horn relay or headlight relay). Swap them. If the engine starts after swapping, the original relay was bad .

2. Listen for the Click: Have someone turn the ignition to "ON" while you listen near the relay. A working relay makes a distinct clicking sound. No click means the relay coil is likely dead .

3. Use a Multimeter: You can test for continuity and resistance. The coil should read between 50-120 ohms. Apply 12V to the coil terminals, and you should hear a click and see continuity across the switch terminals .

Step-by-Step Guide to Replacing the Fuel Pump Relay

Replacing the fuel pump relay is one of the easiest repairs you can do on a Honda CRV. No special tools are needed, and it takes about 10 minutes.

What you need:

  • A new fuel pump relay (make sure the part number matches your original)
  • A flathead screwdriver (optional, for prying)
  • Safety gloves (optional)

Steps:

  1. Disconnect the battery. Always disconnect the negative battery terminal before working on any electrical component. This prevents shocks and protects your car's electronics .

  2. Locate the relay. Use the directions above to find the relay in your fuse box.

  3. Remove the old relay. Grasp the relay firmly and pull it straight out of its socket. If it's tight, use a flathead screwdriver to gently pry it out. Do not pull on the wires attached to the socket .

  4. Compare the new relay. Hold the new relay next to the old one. Make sure the prongs are the same shape and number. This ensures compatibility .

  5. Install the new relay. Push the new relay firmly into the socket until it clicks into place. Make sure it's fully seated.

  6. Reconnect the battery. Reattach the negative battery terminal and tighten it.

  7. Test the engine. Turn the ignition to "ON" and listen for the fuel pump to prime. Then start the engine. If it starts and runs, you've solved the problem.

Other Possible Causes of No-Start Problems

If replacing the fuel pump relay doesn't fix the issue, the problem could be something else. Here are other common causes:

  • A blown fuse – Check the fuel pump fuse in the same fuse box .
  • A faulty fuel pump – The pump itself may have failed .
  • A clogged fuel filter – This restricts fuel flow to the engine .
  • Bad wiring or corroded connectors – Inspect the wires leading to the relay and pump .
  • A failing crankshaft position sensor – This sensor tells the ECU when to trigger the fuel pump .

When to Call a Professional

While replacing a fuel pump relay is a simple DIY job, sometimes you need a mechanic. Call a professional if:

  • You can't locate the relay in either fuse box
  • You've replaced the relay but the problem persists
  • You're not comfortable working with electrical components
  • You suspect a deeper issue like a bad ECU or wiring harness

A qualified mechanic can diagnose the problem accurately using specialized tools.

Summary

The Honda CRV fuel pump relay is typically in the under-hood fuse box on the driver's side. Check the diagram on the lid for labels like "FUEL PUMP," "FP," or "PGM-FI." If it's not there, look in the interior fuse box behind the dashboard. Replacing it is straightforward: disconnect the battery, pull out the old relay, push in the new one, and reconnect the battery. This simple fix often resolves no-start issues and saves you a trip to the shop.
