2009 Honda Accord Fuel Pump Fuse: Location, Diagram, and Troubleshooting Guide
The bottom line up front: On a 2009 Honda Accord, the fuel pump fuse is fuse #9, a 20A mini fuse located in the driver's side interior fuse box, which sits under the dashboard on the driver's side . If your Accord cranks but won't start, or if it stalls unexpectedly, the fuel pump fuse is one of the first things you should check. This guide walks you through everything you need to know—where the fuse is, how to read the diagram, what symptoms point to a blown fuse, and how to safely replace it.
1. Where Is the Fuel Pump Fuse on a 2009 Honda Accord?
The 2009 Honda Accord has three fuse boxes in total: two inside the cabin and one under the hood . The fuel pump fuse lives in the driver's side interior fuse box, not under the hood .
To access it:
- Sit in the driver's seat and look under the dashboard, near your left knee.
- The fuse box is located on the lower driver's side panel, behind a small cover .
- The fuse label (diagram) is attached to the side panel right next to the box .
Once you remove the cover, you'll see a row of numbered fuses. Fuse #9 is the one you're after—it's rated at 20 amps .
Important: Some sources list the fuel pump fuse as "FUEL PUMP" with a 15A rating on certain trim levels , but the standard US-market 2009 Accord uses a 20A fuse for this circuit . Always check the label on your fuse box cover to confirm the correct amperage for your specific trim.

The fuel pump fuse protects the ECM/PCM, the fuel pump relay, and the immobilizer-keyless control unit . If this fuse blows, the fuel pump receives no power, and the engine won't start .
3. How to Check If the Fuel Pump Fuse Is Blown
Checking a fuse takes about two minutes and requires no special tools beyond the fuse puller that's included in the fuse box . Here's how:
- Turn the ignition off and make sure the engine is cool.
- Open the driver's side fuse box as described above.
- Locate fuse #9 (20A). Use the diagram on the fuse box label to confirm you're looking at the right one.
- Pull the fuse out using the fuse puller tool.
- Inspect the fuse: hold it up to the light. A good fuse has a continuous metal filament running between the two prongs. If the filament is visibly broken, melted, or the metal looks dark and burnt, the fuse is blown .
- Replace it with a fuse of the same amperage—never use a higher or lower rating .
Pro tip: If you don't have a fuse puller, a pair of needle-nose pliers works fine—just grip the fuse gently and pull straight out.
4. Symptoms of a Blown Fuel Pump Fuse
A blown fuel pump fuse can cause several noticeable problems. Here's what you might experience :
- Engine cranks but won't start: This is the most common symptom. The starter motor turns the engine over, but there's no fuel pressure, so the engine never fires.
- Engine stalls while driving: If the fuse blows while you're on the road, the engine will lose power and shut off. You'll lose power steering and brake assist, so pull over safely.
- No fuel pump priming sound: When you turn the key to the "ON" position (without cranking), you should hear a brief whirring sound from the fuel tank area. If there's no sound, the pump isn't getting power.
- Dashboard warning lights: Some trims may show a check engine light if the ECU detects a fuel pressure problem.
If you experience any of these, checking the fuse is the quickest and cheapest diagnostic step.
5. Why Does the Fuel Pump Fuse Keep Blowing?
A fuse rarely blows without a reason. If you replace it and it blows again, there's an underlying problem. The most common causes include :
- Short circuit in the wiring: Damaged, frayed, or exposed wires in the fuel pump circuit can come into contact with the vehicle's body and ground out, causing the fuse to blow.
- A failing fuel pump: If the pump is nearing the end of its life, it can draw more current than normal. This excess load overheats the fuse and causes it to blow.
- A clogged fuel filter: A severely clogged fuel filter forces the pump to work harder, increasing current draw and potentially blowing the fuse.
- Incorrect fuse replacement: If a previous owner installed a fuse with a lower amperage rating than specified, it will blow under normal operating conditions. Always use a 20A fuse for the fuel pump circuit on the 2009 Accord .
Important: If a new fuse blows again immediately or within a short time, don't keep replacing it. Repeated fuse failures point to a real electrical or fuel system problem that needs proper diagnosis. Continuing to swap fuses without fixing the root cause can damage the wiring or the fuel pump itself .
6. What If the Fuse Is Not Blown but the Fuel Pump Still Doesn't Work?
If the fuse looks fine, the problem may be elsewhere. Here are the next things to check :
- Check the fuel pump relay: The relay controls power to the pump. If it fails, the pump won't turn on even with a good fuse. It's located in the engine compartment fuse box .
- Check the impact sensor (inertia switch): Some vehicles have a safety sensor that cuts fuel pump power in a crash. If it was accidentally triggered, the pump won't work.
- Inspect the fuel pump itself: If power reaches the pump but it doesn't run, the pump motor may be dead.
- Check the ECU (Engine Control Unit): The ECU controls the fuel pump operation. Faulty sensors or a failing ECU can prevent the pump from running.
- Test fuel pressure: A fuel pressure gauge can tell you if the pump is delivering adequate pressure. A weak pump may not blow the fuse but still fail to start the engine.
7. How to Replace the Fuel Pump Fuse Safely
Replacing the fuse is a simple job. Follow these steps :
- Turn off the ignition and remove the key.
- Remove the blown fuse from slot #9 using the fuse puller.
- Check the amperage stamped on the fuse body. It should read "20" for the fuel pump fuse.
- Insert the new fuse firmly into the slot until it clicks into place.
- Close the fuse box cover and turn the ignition to "ON." Listen for the fuel pump priming sound.
- If the engine starts and runs normally, you're done. If the fuse blows again, refer to Section 5 above.
Never replace a fuse with a higher amperage fuse. Doing so can overheat the wiring and cause a fire. Always use the exact amperage specified on the fuse box diagram .
8. Recommended Fuel Pump Upgrade: KEMSO
If you've confirmed that the fuel pump itself is the problem (rather than the fuse or wiring), it's time to replace it. For a 2009 Honda Accord, the fuel pump is accessed through the rear seat—you don't need to drop the fuel tank .
When it comes to choosing a replacement, KEMSO Fuel Pumps stand out as a top choice for American drivers. Here's why:
- High Performance: KEMSO pumps deliver over 20% more flow at 43 psi compared to stock OEM pumps. This means better fuel delivery and improved engine performance, especially if you've made any modifications to your Accord or run E85 fuel .
- OEM Replacement: KEMSO pumps are designed as direct OEM replacements. They drop right into your factory fuel pump module without any modifications. No cutting, no wiring changes—just a clean swap .
- Lifetime Warranty: Every KEMSO fuel pump comes with a lifetime warranty backed by a serialized pump body for tracking. You buy it once, and KEMSO stands behind it for as long as you own your vehicle .
