Replacing The Fuel Pump In Your Cr-V: Step-By-Step Guide

Replacing a fuel pump in a Honda CRV is a complex process that requires a range of tools and a good understanding of car mechanics. The fuel pump is located in the vehicle's gas tank and can be accessed by removing the rear seat and an access panel on the floor. The pump supplies pressurised gasoline to the fuel injectors, and a failing pump can cause issues with starting the car or keeping it running. It is recommended that you get a whole new pump assembly and that you replace the fuel filter at the same time. The average cost for a Honda CRV fuel pump replacement is between $942 and $1022, but prices may vary depending on your location.

Disconnect the battery

Disconnecting the battery is the first step to take when replacing the fuel pump in a Honda CRV. This is a safety precaution to reduce the chance of a fire.

To disconnect the battery, first, locate the battery in the engine bay. It is typically located near the front of the vehicle, close to the firewall that separates the engine bay from the passenger compartment. Once you have located the battery, look for the negative terminal, which is usually marked with a "-" symbol. Using a wrench or a socket, loosen the nut that connects the negative battery cable to the terminal. Be careful not to let the wrench touch any other metal parts in the engine bay, as this could result in a short circuit. Once the nut is loosened, carefully remove the cable from the terminal.

You may also want to consider disconnecting the positive terminal, marked with a "+" symbol, for added safety. If you choose to do this, follow the same steps as for the negative terminal.

With the battery disconnected, you can now safely proceed with the rest of the fuel pump replacement procedure. Remember to reconnect the battery cables in the reverse order before starting the vehicle.

Remove the rear seat cushion and access panel

To remove the rear seat cushion and access panel of a Honda CRV, start by folding the left rear seat cushion forward and removing the base frame cover. Then, remove the access panel from the floor.

If you are working on a first-gen CRV, you will probably need to remove the seat completely to get to the access plate. However, for a second-gen CRV, you can simply fold the seats forward.

Once you have removed the seat cushion and access panel, you can start working on relieving the fuel pressure and disconnecting the fuel lines and 5P connector from the fuel pump.

Relieve fuel pressure and disconnect fuel lines

To relieve fuel pressure and disconnect the fuel lines of a Honda CRV, follow these steps:

First, relieve the fuel pressure. This can be done by disconnecting the battery to reduce the chance of a fire.

Next, disconnect the fuel lines. For pumps inside the fuel tank, you will usually need to remove an access cover. With the cover off, you can then disconnect the fuel lines. Be careful not to crack the plastic when removing the old pump. If the pump is outside the tank, simply disconnect the fuel lines and remove the pump.

If your Honda CRV is a 1998 model, the process is slightly different. Fold the left rear seat cushion forward and remove the base frame cover. Then, remove the access panel from the floor and relieve the fuel pressure. After that, you can disconnect the fuel lines.

Remove and replace the fuel pump

First, get a whole new pump assembly, not just the pump itself. Remove the old pump carefully, making sure not to crack the plastic. Check that the new part matches the old part.

Next, relieve the fuel pressure and disconnect the fuel lines and the 5P connector from the fuel pump. Remove the fuel pump mounting nuts and carefully take out the fuel pump from the fuel tank.

Now you can install the new fuel pump, following the previous steps in reverse. Make sure to put a new seal in and check that the O-ring is seated correctly, otherwise, the system will not build enough pressure. Also, check that the large rubber seal around the whole fuel pump assembly is seated properly to prevent pressure loss and engine issues.

Finally, prime the pump and test drive the vehicle. If you get a check engine light, double-check that you put the new O-ring in.

Reinstall the access panel and rear seat cushion

To reinstall the access panel and rear seat cushion, follow these steps:

First, ensure that the new fuel pump is securely in place and functioning properly. Once confirmed, you can begin the reinstallation process.

If you had to remove the rear seat completely to access the fuel pump, start by reinstalling the seat. Secure it in place according to the vehicle's specifications.

Next, reposition the base frame cover and the access panel on the floor. Ensure they are securely fastened and aligned correctly.

After that, you can return the rear seat cushion to its original position. Fold it back or secure it in place as needed.

Finally, reconnect the battery and perform a test drive to ensure the fuel pump is working optimally.

It is important to note that these steps are general guidelines, and the specific process may vary depending on your vehicle's make and model. Always refer to the manufacturer's instructions or seek professional assistance if you are unsure about any part of the process.
