Replacing Fuel Pump In 2002 Honda Crv: Step-By-Step Guide

Replacing the fuel pump in a 2002 Honda CRV is a complex task that requires careful attention to safety. The fuel pump is responsible for delivering gas from the fuel tank to the fuel injectors, and it is typically located inside or outside the fuel tank. Due to the risk of fire, it is recommended that this job be left to professionals. The cost of replacing a fuel pump can vary depending on location, but it typically ranges from $942 to $2185. Symptoms of a failing fuel pump include leaking, unusual noises, loss of engine power, and the car not starting.

Disconnect the battery

Disconnecting the battery of your 2002 Honda CR-V is a simple task that can be completed in just a few minutes. Here is a step-by-step guide on how to do it:

Step 1: Park your car on a level surface and engage the parking brake. It is important to ensure that your car is securely parked and will not move during the process.

Step 2: Locate the battery. The battery of your 2002 Honda CR-V is typically located in the engine bay, near the front of the vehicle. Open the hood of your car and identify the battery, which is a rectangular unit with two terminals, labelled positive (+) and negative (-).

Step 3: Prepare your tools. You will need a wrench or a pair of pliers to loosen the battery terminal clamp. It is recommended to use a 10 mm wrench or an adjustable wrench. Have some rags or towels ready to wipe up any corrosion or dirt that may be present on the battery terminals.

Step 4: Disconnect the negative terminal first. Loosen the clamp on the negative terminal by turning it counterclockwise with your wrench or pliers. Once it is loose, carefully remove the clamp from the terminal. You may need to wiggle it gently to detach it completely. Place the clamp aside, ensuring it does not touch any metal parts of the car to avoid creating a short circuit.

Step 5: Disconnect the positive terminal. Use the same process as for the negative terminal. Loosen the clamp by turning it counterclockwise and then remove it from the terminal. Place the positive clamp away from any metal surfaces.

Step 6: Clean the battery terminals. If there is any corrosion or dirt buildup on the terminals, use a wire brush or a mixture of baking soda and water to clean them. This step is important to ensure a good connection when you reconnect the battery.

Step 7: Ensure the battery is secure. Check that the battery is properly mounted and secured in place. If it was held down by the clamps, make sure to secure it with a battery tie-down or a bracket.

Step 8: Reinstall the battery clamps. If you are immediately reconnecting the battery, reinstall the positive clamp first, followed by the negative clamp. Tighten the clamps securely by turning them clockwise with your wrench or pliers.

Step 9: Apply a layer of grease. After tightening the clamps, apply a small amount of grease or petroleum jelly to the battery terminals. This will help prevent corrosion and make it easier to disconnect the battery in the future.

Remember to always exercise caution when working with car batteries. Wear protective gear, such as gloves and eye protection, to shield yourself from battery acid. Additionally, always disconnect the negative terminal first and reconnect it last to reduce the risk of electrical shorts and sparks.

Remove the rear seat

To remove the rear seat of a 2002 Honda CRV, first identify whether the seat can be folded forward or needs to be removed completely. If it needs to be removed, take out the bolts holding the seat in place and set the seat aside. If the seat can be folded forward, simply release the latch and fold the seat down. Once the seat is moved, you will have access to the carpet, which will need to be removed to access the fuel pump.

Drain the fuel

To drain the fuel from a 2002 Honda CR-V, you will need to take the necessary safety precautions and prepare the appropriate equipment. Here is a step-by-step guide:

• Safety Precautions: Working with the fuel system can be dangerous, so it is crucial to take the necessary safety measures. Ensure you are in a well-ventilated area, preferably outdoors, to allow the fumes to dissipate. Keep fire extinguishers nearby in case of any accidents. It is also recommended to disconnect the battery to reduce the risk of fire.
• Locate the Fuel Tank: The fuel tank is located at the rear of the vehicle, underneath the driver's side rear seat. You may need to remove or fold forward the rear seat to access the fuel tank compartment.
• Identify the Drain Plug: The 2002 Honda CR-V fuel tank should have a drain plug towards the back of the tank on the driver's side. It might be covered with undercoating, so you may need to scrape away the coating to access the drain plug.
• Position the Vehicle: Ensure that the vehicle is parked on a level surface to facilitate easy and complete drainage of the fuel.
• Prepare the Equipment: You will need a container to collect the drained fuel, such as a gas can or a suitable container. Additionally, you will need a siphon hose with a bulb pump or a manual pump designed for draining fuel.
• Drain the Fuel: Place the container below the drain plug to collect the fuel. Remove the drain plug, being careful not to lose it, and allow the fuel to drain into the container. If using a siphon hose, insert one end into the fuel tank and start siphoning the fuel into the container.
• Dispose of the Fuel Properly: Once you have drained the fuel, ensure that you dispose of it properly and in accordance with local regulations. Do not pour the fuel down the drain or into the environment. Take the collected fuel to a designated disposal facility or recycling centre.
• Reinstall the Drain Plug: After draining the fuel and allowing the tank to dry, reinstall the drain plug securely. Ensure that the plug is tightened appropriately to prevent any leaks.

Remember to exercise caution throughout the process, as gasoline is highly flammable. If you are uncomfortable with any part of the procedure, it is recommended to consult a professional mechanic or a specialist.

Remove the access cover

To remove the access cover of your 2002 Honda CRV to replace the fuel pump, you will first need to disconnect the battery to reduce the chance of a fire.

Next, you will need to remove the rear seat to access the pump. You may need to completely remove the seat, rather than just folding it forward. Once the seat is out of the way, you will need to remove the carpet to expose the cover.

Now, you should see the cover and the wiring harness that connects to the fuel pump. Remove the wiring harness and set it aside.

At this point, you will need to remove the lock ring that holds the access cover in place. This can be done with a special tool, or carefully with a flat-head screwdriver. Gently tap the screwdriver against the lock ring in different spots until it loosens. Be careful not to hit the same spot repeatedly, as this could crack the plastic. Once the lock ring is loose, you can continue to loosen it by hand.

With the lock ring removed, you can now carefully lift out the access cover. Be cautious not to spill any fuel that may be remaining in the tank.

Replace the pump and pre-pump filter screen

To replace the fuel pump and pre-pump filter screen on a 2002 Honda CR-V, you will first need to disconnect the battery to reduce the chance of a fire. Next, you will need to access the fuel pump. In some cases, you will need to drain the fuel before removing the access panel to reach the pump. In other cases, there may be an access cover that can be removed to reach the pump.

Once you have accessed the fuel pump, you will need to remove it. This may involve disconnecting fuel pump supply and return hoses, EVAP system hoses, and electrical connections to the pump. You may also need to remove the fuel tank to gain access to the pump.

When the pump is out, you can install the new pump. Attach any reusable brackets and pick-up screens to the new pump, then insert it into the fuel tank. If your fuel system uses an in-line external filter, it should also be replaced at this time. Reattach all hoses and electrical connections.

Finally, add fuel to the tank and run the engine to test for leaks. Ensure there are no fuel leaks and that the problem is solved.
