The fuel pump relay in a 2013 Honda Accord is typically located in the interior fuse/relay box under the driver’s side dash. If you don’t find it there, check the engine compartment fuse box for a relay labeled “FUEL PUMP” or “FUEL PUMP RELAY.”
Understanding where it fits in your car
The fuel pump relay is a small electrical component that controls power to the fuel pump. If the relay fails or becomes corroded, the engine may crank without starting or stall after starting. Because manufacturing and trim options can shift relay placement, always verify with the fuse box diagram on the cover or the owner's manual for your exact vehicle.
Interior fuse box location
Before the following list, note that many 2013 Accords place the fuel pump relay in the interior fuse/relay box behind the driver’s-side kick panel. Use the diagram on the inside of the fuse box cover to confirm the exact relay position.
- Open the driver’s-side kick panel and remove the fuse box cover.
- Identify the relay labeled “FUEL PUMP RELAY” or a similar designation on the diagram.
- Pull the relay straight out using needle-nose pliers if needed to inspect or swap it.
- If you’re testing, you can swap it with another relay of the same type from the box (e.g., A/C relay) to see if the problem follows the relay.
- Replace with a new, OEM-recommended relay if swapping indicates a faulty unit.
Locating the fuel pump relay in the cabin fuse box is usually the quickest path. If you locate the marked relay and it tests out, you’ve likely identified the source of an intermittent starting issue or stalling.
Engine compartment fuse/relay box location
If the interior box doesn’t house a labeled fuel pump relay, or your vehicle’s layout differs by market or trim, check the engine bay fuse/relay box. The cover diagram there also shows relay locations and may include a “FUEL PUMP” designation.
- Open the hood and locate the engine compartment fuse/relay box (typically near the firewall or along the fender).
- Remove the cover and read the diagram to confirm the “FUEL PUMP RELAY” position.
- Remove the relay just like in the interior box and inspect or swap with a known-good relay of matching type.
- Reinstall the cover and test the electrical system by attempting to start the car or by confirming power to the pump circuit with a multimeter when key is on.
If the engine won’t start and the relay tests normal, the problem may lie with the fuel pump, wiring, or related sensors. The engine bay box provides an alternative reference point when the interior box isn’t conclusive.
How to test a suspected fuel pump relay
Testing can confirm whether the relay is the culprit. If you’re not comfortable with electrical work, have a professional diagnose it. Here are basic steps typically used by DIYers:
- Swap the suspected relay with a like-for-like relay from the same box (same amperage and pin count). If the problem moves with the relay, the relay is likely faulty.
- With the key to “ON” (do not crank), listen for the fuel pump priming sound (in some cars you may hear a faint whine). If no sound, check the relay circuit and 12V power at the pump connector.
- Use a multimeter to verify that the relay is receiving control signal from the ECU and delivering power to the fuel pump when commanded.
Proper testing helps distinguish a faulty relay from a pump or wiring issue.
Summary
For a 2013 Honda Accord, start by checking the interior fuse/relay box under the driver’s dash for the FUEL PUMP RELAY. If it’s not there, inspect the engine compartment fuse box using its diagram. Whether you’re replacing a suspected relay or confirming a starting issue, using the diagram on the fuse box cover and, if needed, swapping with a known-good relay are practical first steps. If problems persist, consult a technician to inspect the fuel pump, wiring, and related sensors.
