Fuel Pump Replacement Cost For Honda Accord

Replacing a fuel pump on a Honda Accord can cost anywhere from $700 to $3,000, depending on the model year of the car. The labour costs are estimated to be between $85 and $175, while the parts are priced between $86 and $1,295. The process of replacing the fuel pump involves siphoning out the gas tank, raising and securing the car, disconnecting the fuel-sending unit, and removing the fuel pump before installing a new one.

Diagnosing a faulty fuel pump

• Check Engine Light: If the check engine light is on and your car is idling rough or stalling, it could indicate a bad fuel system. A slowly failing fuel pump may cause the fuel pressure and volume to degrade, resulting in a lack of fuel relative to the amount of air, triggering the check engine light.
• Whining Noise: A high-pitched whining or humming noise coming from the fuel tank area, towards the rear of the car, could indicate a failing fuel pump. This noise is often noticeable as the pump primes the fuel lines when you first turn the key to the "ON" position.
• Stalling: If your car stalls and then restarts after several minutes, it could be due to low fuel pressure caused by a faulty fuel pump.
• Trouble Starting: A bad fuel pump can cause difficulty in starting your car or even prevent it from starting altogether.
• Power Loss: A sudden loss of power when you try to accelerate could be another symptom of a failing fuel pump. It might not be able to keep up with the engine's demands, resulting in a noticeable drop in power.
• Fuel Pressure Test: One way to test for a faulty fuel pump is to check the fuel pressure. You can loosen the fuel pressure relief nut on the fuel rail and observe if there is any leakage. However, it is recommended to use a fuel pressure gauge to accurately measure the fuel pressure.
• Fuel Pump Relay: If the fuel pump relay isn't activating, there won't be any voltage where the fuel pump harness connects to the pump. You can test the voltage to determine if power is getting through.
• Fuel Filter: A clogged fuel filter can restrict fuel flow, contribute to engine misfires, and put additional strain on the fuel pump. Regularly checking and replacing the fuel filter as per the maintenance guidelines is essential.

Step-by-step replacement guide

Step 1 – Siphon out the gas tank

Take a tube and insert it into the tank, through the gas cap. Create a vacuum by blowing into the tank through the tube and pour the gasoline into a safe container. Drain out as much gas as possible. If you have access to one, use a vacuum pump to avoid accidentally sipping up gasoline.

Step 2 – Raise and secure the car

Use a jack on one of the car's safety points and raise it. Position jack stands under the car to secure it into the air.

Step 3 – Disconnect the fuel-sending unit

Open the access hatch located inside the trunk and disconnect the fuel-sending unit.

Step 4 – Disconnect the fuel lines

Remove the rear left wheel and disconnect the four fuel lines located behind it. There are two hard lines, a high-pressure line, a brass line that connects directly to the tank, and a large line for fuel input.

Step 5 – Remove the tank straps

Place a hydraulic jack with a long piece of wood under the tank. Loosen and remove the 14mm bolts holding the tank straps in place. Once the straps are off, slowly lower the tank to relieve the pressure from the jack.

Step 6 – Remove the fuel pump

Disconnect the clip on top of the fuel pump and use a 10mm socket to remove the nuts securing the fuel pump to the tank. Pull the unit out and remove the pump from its bracket.

Step 7 – Install the new pump

Mount the new pump to its holder, ensuring it is correctly positioned inside the gas tank. There is a small plastic container inside the tank; position the pump so that it sits inside this container, where the fuel pick-up is.

Step 8 – Mount the fuel tank and lines

Raise the tank and secure the straps. Reconnect all the fuel lines, ensuring the high-pressure line is tightened. Put the wheel back on and lower the vehicle. Pour some fuel and start the engine.

Additional notes:

• This guide applies to the 1990-2002 Honda Accord.
• The cost of replacing a fuel pump for a Honda Accord varies depending on the model year and labour costs. The parts typically range from $86 to $1,295, while labour costs range from $85 to $1,077.
• It is recommended that fuel filters are replaced at the same time as the fuel pump.

Safety precautions

The fuel pump in a Honda Accord is located within the fuel tank, which is usually at the rear of the vehicle. Replacing the fuel pump can be a complex procedure, and it is recommended that you let a repair shop handle the job unless you are very experienced in auto repair.

• Work in a well-ventilated area: Fuel vapors are flammable and can be dangerous.
• Disconnect the battery: Before working on the fuel system, disconnect the battery to prevent electrical hazards and reduce the chance of a fire.
• Avoid sparks: Do not use tools that could create sparks near the fuel tank.
• Use proper safety gear: Wear safety glasses and gloves to protect yourself from fuel spills.
• Consult your owner’s manual: Refer to your Honda Accord’s owner’s manual for specific instructions and safety precautions.
• Siphon out the gas tank: Before accessing the fuel pump, you will need to siphon out the gas tank to drain as much gasoline as possible. You can use a tube to create a vacuum and pour the gasoline into a safe container.
• Raise and secure the car: Use a jack to raise the car at one of its safety points and position jack stands under the car to secure it in the air.
• Disconnect the fuel lines: There are several fuel lines that need to be disconnected, including hard lines, a high-pressure line, a brass line, and a fuel input line.
• Remove the fuel pump: Disconnect the clip on top of the fuel pump and use a socket to remove the nuts securing it to the tank. Then, pull out the unit and remove the pump from its bracket.
• Install the new pump: Mount the new pump to its holder, ensuring it is correctly positioned inside the gas tank.

By following these safety precautions and working carefully, you can help ensure a smooth and safe fuel pump replacement process for your Honda Accord.

Signs that your fuel pump needs replacing

Fuel pumps deliver pressurised gasoline to the fuel injectors in a car's engine. They are expected to wear out over time, especially in vehicles with higher mileage. Here are some signs that your fuel pump needs replacing:

Won't start or difficulty starting

A weakened or aging fuel pump may cause your engine to crank multiple times before starting. If the fuel pump has broken or failed, the car may not start at all, though the ignition will still attempt to turn over.

Speed surges or lags

A faulty fuel pump can cause your engine to misfire or fail to maintain an even speed. If you notice your vehicle surging or lagging intermittently, you may need to get your fuel pump checked.

Sputtering or stalling sounds

A worn-out fuel pump can cause sputtering or stalling sounds, even if there is no change in performance. Without a precise measurement of fuel, the engine cannot produce the steady hum it would when functioning properly.

Hums, howls or whines

A faulty fuel pump can produce many different types of sounds, from subtle to very distinct. When working properly, your vehicle's fuel pump will likely make a barely audible hum. Any increase or sudden change in this sound could indicate that your pump requires an inspection, especially if you hear a howl or a whine.

Leaks or unusual noises

If your fuel pump is leaking or making a lot of noise, get it looked at right away. A failing fuel pump will not create enough pressure in the fuel system, possibly causing a loss of engine power or preventing the car from starting.
