In most Honda CR-Vs, the fuel pump relay is located in the under-hood fuse/relay box on the driver's side of the engine bay. Refer to the diagram on the fuse box lid for the exact position and label (often "FUEL PUMP" or "FP").
The fuel pump relay controls the electrical supply to the pump that pressurizes the fuel system. If it fails or the circuit is faulty, the engine may crank but fail to start, or stall soon after starting. The exact relay position can vary slightly by model year and trim, so always confirm with the owner's manual or the box diagram.
Where it's typically located by CR-V generation
To help you find the relay quickly, here is a general guide by generation. Always verify with the fuse box diagram on the cover.
- Second generation (2002–2006): Under-hood fuse/relay box on the driver's side of the engine bay; look for a relay labeled "FUEL PUMP", "FP", or similar on the lid diagram.
- Third generation (2007–2011): Under-hood fuse/relay box with the same labeling convention; refer to the lid diagram for the fuel pump relay location.
- Fourth generation (2012–2016): Under-hood fuse/relay box; the "FUEL PUMP" relay is typically one of the relays in the main bank with a diagram on the cover.
- Fifth generation (2017–present): Under-hood fuse/relay box; position remains in the standard relay bank, with the lid diagram indicating "FUEL PUMP" or "FP".
Concluding paragraph: If you still can't locate the relay, check the interior fuse box behind the driver's side kick panel or consult the official Honda service information or your owner's manual for the exact diagram for your VIN.
What to do if you can't find it in the engine bay
Some trims or regional variants may relocate relays. If the under-hood box doesn't show a "FUEL PUMP" relay, open the interior fuse box behind the driver's kick panel and examine the diagrams there. The exact labeling is included on the cover or in the owner's manual.
How to test or confirm the relay is functioning
Before testing, ensure the vehicle is off and the keys are removed. If you suspect a faulty relay, you can perform a safe, basic check.
- Locate the fuel pump relay and a known-good relay with the same pin count and coil resistance.
- Swap the relays temporarily with the same-type relay and attempt to start the engine; if it starts, the relay is likely at fault.
- Listen for the fuel pump priming when turning the ignition to the "ON" position; no sound could indicate a bad relay or pump.
- Use a multimeter to check for continuity between the relay's coil terminals when energized; consult the relay's spec sheet for expected values.
Concluding paragraph: If the swap does not fix the issue, or you're unsure about testing, have the vehicle inspected by a qualified technician to avoid fuel-system risks.
Summary
The fuel pump relay on a Honda CR-V is usually found in the under-hood fuse/relay box on the driver's side of the engine bay, with the lid diagram showing the exact position. If not found there, inspect the interior fuse box behind the driver's kick panel. Always verify with the owner's manual or service diagrams, and exercise caution when handling electrical components.
