The fuel pump fuse on a 2004 Honda Pilot is typically located in the engine bay’s under-hood fuse/relay box and is a 15-amp fuse labeled FUEL PUMP (or FUEL) on the lid’s diagram.
Location and labeling
Here’s how to identify the exact slot and ensure you’re checking the right component.
Under-hood fuse/relay box
The engine bay houses the main fuse/relay box with a removable lid. In most 2004 Pilots, the fuel pump fuse is the 15A slot labeled FUEL PUMP or FUEL on the box diagram. The box is typically located toward the front of the engine bay and accessible from the driver's side, though exact placement can vary by production batch.
To verify you’ve found the correct fuse, check the list on the fuse box lid and compare it with your owner’s manual for your exact vehicle.
- Fuse label: look for FUEL PUMP or FUEL on the engine bay fuse block.
- Amperage: the fuse is typically 15A; confirm the number on the fuse itself and on the diagram.
- Location: reference the diagram on the underside of the fuse box lid to confirm the exact slot number.
With the label, rating, and location confirmed, you can proceed with inspection or replacement as part of diagnosing fuel issues.
Inspecting and replacing the fuse
When troubleshooting a no-start condition or suspected fuel delivery problem, inspecting the fuse is a quick, safe first step.
Steps to inspect and replace
Follow these steps to inspect the fuse and replace it if necessary.
- Turn off the ignition, remove the key, and open the engine bay fuse box lid. Locate the FUEL PUMP (or FUEL) 15A fuse.
- Remove the fuse with a fuse puller or insulated pliers; look for a broken conductor or discoloration indicating a blown fuse.
- Test the fuse with a multimeter (ohms or continuity). A good fuse should show continuity; a blown fuse will show no continuity.
- Replace with a new 15A fuse of the same type. Do not exceed the rating to avoid wiring damage.
- Close the lid, reconnect any harnesses, and attempt to start the engine to verify operation. If the engine still won’t start, further diagnostics on the fuel pump, relay, wiring, or ECU are needed.
Always exercise caution and avoid high-current tests while working near the fuel system; if unsure, seek professional assistance.
Model variations and verification
Some production runs or trims may place the fuel pump relay or fuse differently, or nest it in a secondary box. Always confirm with a VIN-based diagram or the owner’s manual for your exact vehicle year and trim.
- Some models may have a separate fuel pump relay in the interior fuse box or a secondary relay nearby.
- Labels and slot numbers can vary slightly; rely on the lid diagram and official documentation for accuracy.
If you can’t locate the fuse using these references, consult the owner’s manual, a Honda dealer, or service diagrams specific to your vehicle’s VIN for precise guidance.
