2002 Honda Accord Fuel Pump Fuse: Location, Testing, and Complete Troubleshooting Guide

The bottom line: The fuel pump fuse on a 2002 Honda Accord is a 15-amp fuse located in the interior fuse box on the driver’s side under the dashboard. If your Accord cranks but won’t start, this fuse is one of the first things to check before replacing the fuel pump itself. A blown fuel pump fuse is a common, inexpensive fix that can save you from buying a new pump unnecessarily.

Where to Find the Fuel Pump Fuse on a 2002 Honda Accord

The 2002 Honda Accord has two main fuse boxes, but the fuel pump fuse lives in the interior fuse box. Here is exactly where to look:

Interior fuse box (driver’s side): This box is located under the dashboard on the driver’s side, near the brake pedal. To access it, kneel down and look up under the dash. You will see a rectangular panel. Pull it off by hand or use a flathead screwdriver to gently pry it open. The fuse box diagram is printed on the inside of the cover .

Look for the slot labeled “Fuel Pump” or “IG1 Fuel Pump.” On the 2002 Accord, the fuel pump fuse is fuse #1 in the driver’s side interior fuse box. It is a 15-amp fuse . The fuse protects the fuel pump relay and the PGM-FI main relay circuit .

Under-hood fuse box (engine bay): The engine compartment fuse box is located on the driver’s side of the engine bay, near the battery. This box also contains a 15-amp fuse labeled “FUEL PUMP” that protects the fuel pump relay and circuit. However, the primary fuel pump fuse for the pump itself is the one inside the cabin .

Quick tip: If the diagram on your fuse box cover is missing or faded, take a photo with your phone before removing any fuses. This makes it much easier to put everything back correctly .

How to Test the Fuel Pump Fuse

Testing the fuel pump fuse is a simple job that takes about 5 minutes. You will need a multimeter or a fuse puller.

Step 1: Visual inspection. Remove the 15-amp fuel pump fuse from the interior fuse box. Hold it up to the light. Look through the transparent plastic body. If the metal strip inside is broken, melted, or discolored, the fuse is blown and needs to be replaced .

Step 2: Use a multimeter. Set your multimeter to the continuity setting (the symbol that looks like a sound wave). Touch one probe to each of the two metal prongs on the fuse. If the multimeter beeps or shows a reading near zero, the fuse is good. If it shows no continuity, the fuse is blown .

Step 3: Replace if needed. If the fuse is blown, replace it with a new 15-amp fuse. Never use a higher amperage fuse, as this can damage the wiring or cause a fire. A standard 15-amp mini blade fuse costs less than a dollar at any auto parts store .

What to Do If the Fuse Blows Again

If you replace the fuel pump fuse and it blows immediately or shortly after starting the car, you have a more serious electrical problem. Here are the most common causes:

1. A shorted fuel pump. The fuel pump itself may have an internal short, drawing too much current and blowing the fuse. This is a common failure as the pump ages .

2. Damaged wiring. The wiring harness that runs from the fuse box to the fuel pump may have rubbed against a metal edge, causing a short to ground. Inspect the wiring along the frame and under the rear seat for any signs of chafing or exposed copper .

3. A faulty fuel pump relay. The relay can fail in a way that leaves the circuit closed, causing continuous power draw and overheating. Testing the relay is covered in the next section .

4. Corrosion or moisture. Water intrusion into the fuel pump connector or the fuse box itself can cause corrosion and short circuits. Check for green or white powdery residue on the fuse terminals .

If the fuse keeps blowing after replacing it, do not keep installing new fuses. This can damage the ECU or other components. Have a mechanic perform a circuit test to locate the exact short.

Testing the Fuel Pump Relay (Another Common Culprit)

The fuel pump relay on a 2002 Honda Accord is most commonly located in the interior fuse/relay box under the driver’s side dash. It is usually labeled “FUEL PUMP” or “FP.” On some models, it may be called the “PGM-FI Main Relay” . If you do not find it there, check the engine compartment fuse/relay box near the battery .

Here are three simple ways to test the relay:

Method 1: The “click” test. Turn the ignition key to the ON position (do not crank the engine). Listen near the fuse box. You should hear a faint click as the relay energizes. Then, listen near the rear of the car. You should hear a brief whirring sound for about 2 seconds as the fuel pump primes the system . If you hear neither, the relay or the circuit feeding it may be faulty.

Method 2: The relay swap test. This is the easiest method. Find a relay in the same fuse box that is the same size, shape, and part number. The horn relay is often a good candidate. Swap the fuel pump relay with the horn relay. Turn the key to ON. If the fuel pump now primes (you hear the whirring sound), the original relay was bad. If the horn stops working but the fuel pump still does not work, the problem is not the relay .

Method 3: Listen for fuel pump operation. A healthy fuel pump should run for 2 to 3 seconds when the ignition is turned to the ON position. If you hear nothing, check the fuse first, then the relay, then the pump itself .

Common Symptoms of a Bad Fuel Pump Fuse or Relay

Knowing the symptoms helps you diagnose the problem faster. Here are the most common signs that your fuel pump fuse, relay, or pump itself is failing:

Engine cranks but won’t start. This is the most common symptom. The starter motor turns the engine over, but it never fires up because no fuel is reaching the engine .

No “whirring” sound from the fuel pump. When you turn the key to the ON position, you should hear a faint hum from the rear of the car for about 2 seconds. If you hear nothing, the pump is not getting power .

Intermittent starting issues. Sometimes the car starts fine, other times it does not. This often points to a relay that fails sporadically due to heat or vibration .

Engine stalls while driving. If the relay loses connection while you are on the road, the fuel pump stops, and the engine immediately loses power. This is a dangerous situation .

Loss of power during acceleration. A failing relay may provide inconsistent power, causing the fuel pump to not maintain adequate pressure .

Why You Should Check the Fuel Pump Fuse First

Many people jump straight to replacing the fuel pump when their car does not start. That is a mistake. The fuel pump is expensive and labor-intensive to replace. The fuel pump fuse is a 50-cent part that takes 30 seconds to check. Always start with the easiest and cheapest diagnosis first .

A blown fuel pump fuse can be caused by a simple voltage spike, a momentary short, or just an old fuse that finally gave out. If you replace the fuse and the car starts, you are back on the road for less than a dollar. If the fuse blows again, you then know you have a deeper issue to investigate .

How to Check Fuel Pump Power at the Connector

If the fuse and relay both check out, you need to confirm that power is actually reaching the fuel pump. The fuel pump on a 2002 Accord is located inside the fuel tank. You access it through the trunk or under the rear seat .

What you need: A digital multimeter.

Steps:

  1. Locate the fuel pump access panel. On most 2002 Accords, this is under the rear seat cushion. Remove the seat cushion by pulling up sharply at the front edges .
  2. Remove the access cover. You will see a round or oval metal cover with a wiring harness connected to it.
  3. Disconnect the fuel pump electrical connector.
  4. Set your multimeter to DC voltage (20V range).
  5. Turn the ignition key to the ON position.
  6. Probe the two terminals on the wiring harness side of the connector. You should read 10 to 12 volts DC. If you have voltage, the pump itself is likely bad. If you have no voltage, the problem is in the wiring between the fuse box and the pump .

Fuel Pressure Test: The Final Confirmation

Before you order a new fuel pump, it is wise to confirm the pump is actually the problem with a fuel pressure test. This test separates a bad pump from a bad regulator or a clogged filter.

How to test fuel pressure:

  1. Locate the fuel pressure test port on the fuel rail (near the engine).
  2. Attach a fuel pressure gauge according to the manufacturer’s instructions.
  3. Turn the key to the ON position to prime the pump.
  4. The pressure should read between 41 and 50 psi for a stock 2002 Accord .
  5. If the pressure is below spec, or if it drops rapidly after the pump stops, the pump or fuel pressure regulator is likely faulty.
