1999 Honda CRV Fuel Pump Fuse: Location, Symptoms, and Complete Replacement Guide

If your 1999 Honda CRV cranks but won’t start, or if it stalls while driving, the fuel pump fuse is the first thing you should check. Here is the bottom line: the fuel pump fuse for a 1999 Honda CRV is located in the under-hood fuse box, labeled as “Fuel Pump” or “Fuel Injector,” and it is a 15-amp fuse. If this fuse is blown, the fuel pump will not receive power, and your engine will not start. Replacing this fuse is a simple, low-cost fix that can save you from a costly tow or unnecessary repairs. However, if the fuse blows again, the problem is likely a failing fuel pump or a short circuit in the wiring, and you will need to replace the fuel pump itself. In this guide, we will walk you through how to locate the fuse, test it, diagnose the underlying issue, and ultimately replace the fuel pump if needed. We also recommend the KEMSO brand fuel pump for a reliable, long-lasting replacement.

Where Is the 1999 Honda CRV Fuel Pump Fuse Located?

The 1999 Honda CRV has two fuse boxes: one under the hood and one inside the cabin. The fuel pump fuse is in the under-hood fuse box. To access it, open the hood and look for a black plastic box near the battery on the driver’s side. Remove the cover by pressing the tabs on the sides. On the inside of the cover, you will find a diagram that labels each fuse. Look for a fuse labeled “Fuel Pump” or “Fuel Injector.” It is a 15-amp fuse, usually blue in color. If you cannot find the label, check the owner’s manual for the exact location. The fuse is often in the same row as the main relay and the ignition coil fuse.

How to Test the Fuel Pump Fuse

Testing the fuse is straightforward. You do not need any special tools, just a fuse puller or a pair of needle-nose pliers. First, turn off the engine and remove the key from the ignition. Locate the fuel pump fuse in the under-hood fuse box. Use the fuse puller (usually stored inside the fuse box cover) or pliers to gently pull the fuse out. Hold the fuse up to the light. Look through the transparent plastic body. If the metal strip inside the fuse is broken or burnt, the fuse is blown. If the strip looks intact, the fuse is good. You can also use a multimeter to check for continuity. Set the multimeter to the ohms setting, touch the probes to the two metal prongs on the fuse. If the reading shows zero or close to zero, the fuse is good. If it shows infinite resistance, the fuse is blown.

What Causes the Fuel Pump Fuse to Blow?

A blown fuel pump fuse is usually a symptom of a larger problem. Here are the most common causes:

  1. A failing fuel pump. As the fuel pump wears out, the motor inside it draws more current than normal. This excess current can overload the fuse and cause it to blow. If you replace the fuse and it blows again after a few starts or a short drive, the fuel pump is likely the culprit.

  2. A short circuit in the wiring. The wires that run from the fuse box to the fuel pump can become damaged over time. This is common in older vehicles like the 1999 CRV, where the insulation on the wires can crack or rub against metal parts. A short circuit causes a direct path for current, which blows the fuse instantly.

  3. A faulty fuel pump relay. The relay is a switch that controls power to the fuel pump. If the relay gets stuck in the closed position, it can keep the pump running even when the engine is off, leading to an overload. However, this is less common than a bad pump.

  4. A clogged fuel filter. If the fuel filter is severely clogged, the pump has to work harder to push fuel through the system. This increased workload can cause the pump to draw more current and blow the fuse. Always replace the fuel filter when you replace the pump.

Symptoms of a Bad Fuel Pump Fuse

When the fuel pump fuse is blown, the fuel pump will not run. This leads to several clear symptoms:

  • The engine cranks but will not start. This is the most common symptom. You turn the key, the starter motor spins the engine, but it never fires up. You may hear the starter cranking, but there is no fuel pressure, so the engine cannot ignite.

  • No fuel pump prime sound. When you turn the ignition key to the “ON” position (but not to start), you should hear a faint whirring sound from the rear of the vehicle for about two seconds. This is the fuel pump priming the system. If you do not hear this sound, the pump is not getting power, and the fuse is the first thing to check.

  • The engine stalls while driving. If the fuse blows while you are driving, the engine will lose power and die. You may notice a sudden loss of acceleration, followed by the engine cutting out. This is dangerous, especially on the highway.

  • The check engine light comes on. The ECU will detect a loss of fuel pressure and set a diagnostic trouble code (DTC) such as P0087 (Fuel Rail/System Pressure Too Low) or P0230 (Fuel Pump Primary Circuit Malfunction). You can read these codes with an OBD-II scanner.

How to Replace the Fuel Pump Fuse

Replacing the fuse is a simple job that takes less than five minutes. Here is what you need:

  1. A replacement 15-amp mini blade fuse. You can buy these at any auto parts store for a few dollars. Make sure it is the same amperage rating. Do not use a higher amperage fuse, as this can cause wire damage or a fire.

  2. A fuse puller or needle-nose pliers.

Follow these steps:

  1. Turn off the engine and remove the key from the ignition.

  2. Open the under-hood fuse box.

  3. Locate the fuel pump fuse.

  4. Use the fuse puller to remove the blown fuse.

  5. Insert the new fuse into the same slot. Push it in until it clicks into place.

  6. Close the fuse box cover.

  7. Turn the key to the “ON” position and listen for the fuel pump prime sound. If you hear it, the fuse is good. If not, the fuse may have blown again, or there is another issue.

What to Do If the Fuse Blows Again

If you replace the fuse and it blows again immediately or after a short time, you have a deeper problem. Do not keep replacing the fuse, as this can damage the wiring or the ECU. Instead, follow these steps:

  1. Check the fuel pump relay. The relay is located in the under-hood fuse box. You can swap it with a similar relay from another circuit (like the horn relay) to test it. If the problem goes away, replace the relay.

  2. Inspect the wiring. Look for any damaged, frayed, or melted wires near the fuse box, under the rear seat, and near the fuel tank. Pay special attention to the area where the wires pass through the body. If you find a short, repair it with electrical tape or heat shrink tubing.

  3. Test the fuel pump. The most likely cause is a failing fuel pump. You can test the pump by measuring the resistance at the fuel pump connector. Disconnect the wiring harness from the pump (located under the rear seat or inside the fuel tank). Use a multimeter set to ohms. The resistance should be between 0.5 and 3 ohms. If it is much higher or lower, the pump is bad.

  4. Replace the fuel pump. If the pump is bad, you will need to replace it. This is a more involved job, but it is doable with basic tools. We will cover the replacement process in the next section.

How to Replace the Fuel Pump on a 1999 Honda CRV

Replacing the fuel pump on a 1999 Honda CRV is a moderate DIY job. The fuel pump is located inside the fuel tank, which is under the rear cargo area. You will need to remove the rear seat and the access panel to get to the pump. Here is a step-by-step guide:

Tools and parts you will need:

  • New fuel pump (we recommend KEMSO brand for the best quality)

  • New fuel filter (always replace this at the same time)

  • Socket set (10mm, 12mm, 14mm)

  • Phillips head screwdriver

  • Flathead screwdriver

  • Pry bar or trim removal tool

  • Safety glasses

  • Gloves

  • Fire extinguisher (work in a well-ventilated area, away from open flames)

Step 1: Relieve fuel pressure. The fuel system is under pressure. To safely relieve it, locate the fuel pump relay in the under-hood fuse box and remove it. Start the engine and let it run until it stalls. This will drain the fuel pressure. Then turn the key off and reinstall the relay.

Step 2: Disconnect the battery. Remove the negative battery terminal to prevent any electrical sparks while you work.

Step 3: Access the fuel pump. Fold the rear seat forward. In the cargo area, you will see a trim panel on the floor. Use a pry bar or trim removal tool to lift the panel. Underneath, you will see a metal cover plate held by four screws. Remove the screws with a 10mm socket. Lift the cover plate. You will now see the top of the fuel pump assembly.

Step 4: Disconnect the fuel lines and wiring. The fuel pump assembly has two fuel lines: one for the supply and one for the return. Use a flathead screwdriver to release the quick-connect fittings. Be careful, as there may be residual fuel pressure. Also disconnect the electrical connector by pressing the tab and pulling it off.

Step 5: Remove the fuel pump assembly. Using a hammer and a flathead screwdriver or a lock ring removal tool, tap the locking ring counterclockwise to loosen it. Once it is loose, lift the ring off. Carefully lift the entire fuel pump assembly out of the tank. The tank may be partially full, so be prepared for some fuel spillage. Place the assembly on a clean rag.

Step 6: Replace the pump. The fuel pump assembly consists of a housing, a pump, a strainer, and a sending unit. You can either replace the entire assembly or just the pump. If you are using a KEMSO fuel pump, it is a direct OEM replacement, so it will fit perfectly. Remove the old pump by disconnecting the wires and sliding it out of the housing. Install the new pump in the reverse order. Make sure the rubber grommets and seals are properly seated.

Step 7: Reinstall the assembly. Lower the new assembly back into the tank. Make sure the float arm is not bent and that the assembly is seated correctly. Install the locking ring and tighten it clockwise using a hammer and screwdriver. Reconnect the fuel lines and the electrical connector.

Step 8: Replace the fuel filter. The fuel filter is located along the frame rail, near the driver’s side. Use a 14mm wrench to loosen the fuel line fittings. Remove the old filter and install the new one. Pay attention to the direction arrow on the filter.

Step 9: Reconnect the battery. Reconnect the negative battery terminal.

Step 10: Prime the system. Turn the key to the “ON” position for two seconds, then turn it off. Repeat this three times to prime the fuel system. Then start the engine. It may take a few cranks to start the first time. Check for any fuel leaks at the pump and filter connections.
