The fuel pump relay in a 2000 Honda Accord is typically located in the interior fuse/relay box on the driver’s side under the dash.
This article explains the common placement, how to identify it, and how to test it, so you can diagnose fuel-system issues without guesswork.
Location and identification
Most 2000 Accords place the fuel pump relay in the under-dash fuse/relay box on the driver's side. The box is behind a kick panel near the knee area. The relay itself is a small rectangular module, often labeled FUEL PUMP or PUMP on the underside of the fuse box lid or on a diagram inside the lid. If you don’t find it there, check the engine bay power distribution center as a backup, though that configuration is less common for this model.
Before you begin, ensure the ignition is off and you follow basic safety practices when handling electrical components in a vehicle. If you’re unsure, consult the owner’s manual or a professional mechanic for the exact diagram for your VIN and trim level.
Use the steps below to locate the relay and confirm its position.
- Remove the lower dash panel on the driver’s side to access the interior fuse/relay box.
- Open the fuse/relay box cover and look for a relay labeled FUEL PUMP, PUMP, or something similar. The lid diagram or inside lettering will help identify it.
- Note the relay’s position among the other relays; it is usually one of the relays near the edge of the box for easy swapping.
- If you don’t see a FUEL PUMP label in the interior box, check the engine bay’s power distribution center as an alternate location.
- Refer to the owner’s manual or a service manual for the exact diagram if there is any confusion about labeling in your specific vehicle.
Conclusion: for the 2000 Accord, the interior under-dash fuse/relay box is the standard home for the fuel pump relay, with rare exceptions depending on market or trim. Always confirm with the diagram on the lid.
Testing and verification
If you suspect the relay or the circuit is at fault, use these checks to verify before replacing components. Safety first: avoid sparks near the fuel system and disconnect the battery if you’re performing intrusive wiring tasks.
- Turn the ignition to ON and listen for a distinct click from the relay. No click can indicate the relay isn’t energizing, which could point to an issue in the control circuit.
- Swap the fuel pump relay with another identical relay from the box (for example, a horn or A/C relay of the same type) to see if the fuel pump operates with the swapped relay.
- With the ignition ON, use a multimeter to check for 12V at the fuel pump connector. If voltage is present and the pump doesn’t run, the pump itself or wiring to the pump may be at fault; if no voltage, inspect the relay coil circuit, fuse, and the wiring to the relay.
- Inspect the fuse labeled FUEL PUMP (or similar) in the same fuse block and replace if blown or corroded.
- Check the ground connection for the fuel pump circuit; a poor ground can prevent the pump from energizing even if the relay is functioning.
Bottom line: testing the relay in place or swapping with a known-good unit helps confirm whether the relay is faulty or if there’s another issue in the fuel system.
Summary
In summary, the fuel pump relay on a 2000 Honda Accord is most often found in the interior under-dash fuse/relay box on the driver’s side, clearly labeled on the box lid. If you can’t locate it there, check the engine bay fuse box as a backup and always follow the diagram for your specific vehicle year and trim. When testing, try swapping relays and checking for 12V at the pump connector, while observing proper safety precautions. If in doubt, seek professional help to avoid fuel-system hazards.
