In a 1998 Honda Accord, the fuel pump relay is located in the engine compartment fuse/relay box, typically labeled FUEL PUMP on the lid diagram.
Primary location and how to confirm
The standard placement for this model year is the engine bay fuse/relay box, a black plastic module mounted in the engine compartment. Look for a diagram on the underside of the box cover that maps each relay, including one labeled FUEL PUMP or FUEL PUMP RELAY. If your car has a different configuration or a regional variant, you may also find the relay in the interior fuse panel behind the driver's knee panel.
To minimize ambiguity, always refer to the lid diagram and, if needed, the owner's manual for your exact trim and production region.
However, since you asked specifically for the 1998 Accord, the most common location is the engine bay box. If you can't locate it there, proceed to check the interior panel as a backup.
Before inspecting, ensure safety by turning off the ignition and disconnecting the battery if you're removing fuses or relays.
Here are the steps to locate and identify the fuel pump relay:
- Open the hood and find the engine compartment fuse/relay box, a large black plastic box typically mounted on the driver's side near the front or firewall.
- Open the lid and locate the diagram showing each relay, looking for "FUEL PUMP" or "FUEL PUMP RELAY."
- Pull the suspected relay straight out to inspect its pins for corrosion or damage.
- If you can't find a relay labeled for the fuel pump, refer to the owner's manual or the diagram on the lid for the exact position.
These steps should help you locate the relay quickly and avoid guessing about other relays in the box.
Alternative locations to check
In some Accord configurations, the fuel pump relay may reside in the interior fuse panel under the driver's dash or in a separate power distribution center. If the engine bay box does not show a FUEL PUMP relay, check these panels and their accompanying diagrams.
- Interior fuse/relay box behind the left kick panel (driver's side) under the dash.
- Any secondary fuse/relay panel labeled on the inside cover; follow the lid diagram for mapping.
- Regional or trim differences: some markets may place a related control in a different box or fuse pack.
As always, confirm the exact location with the box lid diagram or a service manual for your exact VIN and trim.
Testing or replacing the fuel pump relay
Testing the relay helps determine whether the problem is the relay itself or the fuel pump circuit. The following steps provide a basic check and replacement approach. If you're not comfortable working with electrical components, seek professional assistance.
- Safely disconnect the negative battery terminal to prevent short circuits.
- Locate the relay, then remove it from its socket and inspect the pins and socket for signs of corrosion or wear.
- Use a multimeter to check for continuity between appropriate pins, or swap with a known-good relay of the same type to test function.
- Reinstall the relay and reconnect the battery. Have someone turn the ignition to START while you listen for the fuel pump relay click or verify fuel pressure with a gauge.
If the relay tests good but the engine still won’t start, the issue may lie with the fuel pump itself, wiring, or the engine control system. Additional diagnostics, such as fuel pressure testing or a fuse/relay continuity check, may be required.
Summary
For a 1998 Honda Accord, the fuel pump relay is most commonly located in the engine compartment fuse/relay box and is labeled FUEL PUMP on the lid diagram. If it isn’t found there, check the interior fuse panel behind the driver's knee or consult the owner’s manual/service manual for the exact trim-specific location. Testing the relay supports determining whether the relay, wiring, or the fuel pump itself is at fault.
