Replacing Fuel Pump In Toyota Camry (2004): Step-By-Step Guide

The fuel pump in a 2004 Toyota Camry is located inside the fuel tank, delivering fuel from the tank to the engine. It is an essential component for optimal engine performance. Over time, the fuel pump can wear out and may need to be replaced. Signs of a failing fuel pump include engine stalling, loss of power, or difficulty starting the vehicle. A replacement fuel pump can be purchased for as little as $20, but the cost of parts and labour can range from $611 to $1,206. While it is possible to replace the fuel pump yourself, it is a moderately complicated job that may be best left to professionals.

Removing the rear seats

To remove the rear seats of a 2004 Toyota Camry, start by depressurizing the fuel system. Open the gas cap, locate the fuse panel under the hood, and remove the relay "C/OPN". Then, start the engine and let it run until it stops. Disconnect the negative battery cable.

Now, you can remove the back seat. Lift up the front edge of the cushions and disconnect the mounting bolt. Lift up the cushion and remove it. Pull up the seatback locks and lower the seatbacks down. Finally, remove the bolts that mount the seat in place.

Disconnecting the fuel pump

The next step is to remove the rear seat, which provides access to the fuel pump. Lift the front edge of the cushions and disconnect the mounting bolt. After that, lift and remove the cushion. Pull up the seatback locks and lower the seatbacks. Finally, remove the bolts that secure the seat in place.

With the rear seat removed, you will have access to the service hole cover, which is located on the floor under the seat. Remove this cover to access the fuel pump. Now, you can proceed to disconnect the electrical and fuel line connectors from the fuel pump. At this point, the fuel pump will be ready for removal.

It is important to note that working with the fuel system can be dangerous, and precautions must be taken to prevent the risk of fire. It is recommended that unless you are experienced in auto repair, it is best to leave this task to a professional mechanic or a repair shop.
