Replacing Fuel Pump In 2002 Toyota Camry: Step-By-Step Guide

If your 2002 Toyota Camry is not running as reliably as it used to, you may have a fuel pump problem. The fuel pump is located under the rear passenger seats in the fuel tank. To replace it, you will need a wrench, a screwdriver, and a replacement fuel pump. Start by depressurizing the fuel system by opening the gas cap and removing the relay C/OPN from the fuse panel under the hood. Then, start the engine and let it run until it stops. Disconnect the negative battery cable, remove the rear seat, and expose the fuel pump panel by pulling back the carpet. You can then remove the fuel pump by disconnecting the power wires and fuel lines, unscrewing the ring, and lifting it out. Install the new fuel pump by following these steps in reverse. Finally, pressurize the fuel system by turning the ignition on and off in intervals of 10 seconds, repeating this sequence 5 to 10 times.

Removing the rear seat

To remove the rear seat of a 2002 Toyota Camry, you will need to open the rear doors and pull the clips found underneath the rear seat pad to disconnect the pad. Then, tip up the lower seat cushion and pull it away from the seat to remove it.

Next, lift up the front edge of the cushions and disconnect the mounting bolt. You can then lift and remove the cushion. Pull up the seatback locks, and lower the seatbacks down. Remove the bolts that mount the seat in place.

Now, you should be able to see the service hole cover. Remove it to expose the fuel pump.

Disconnecting power wires and fuel lines

Disconnecting the power wires and fuel lines is a crucial step in replacing the fuel pump of a 2002 Toyota Camry. Here is a detailed, step-by-step guide to help you through the process:

Step 1: Before you begin, it is important to depressurize the fuel system. Open the gas cap and locate the fuse panel under the hood. Remove the relay "C/OPN". Then, start the engine and let the car run until it stops. Finally, disconnect the negative battery cable.

Step 2: Gain access to the fuel pump by removing the rear seat of the car. Lift up the front edge of the cushions and disconnect the mounting bolts. Lift and remove the cushions, and then pull up the seatback locks to lower the seatbacks.

Step 3: Remove the bolts that mount the seat in place. Locate and remove the service hole cover, which is usually on the floor under the seat. This will expose the fuel pump.

Step 4: Disconnect the power wires and fuel lines from the fuel pump. Remove the electrical and fuel line connectors. You may also need to remove any retaining bolts holding the fuel pump in place.

Step 5: With the wires and fuel lines disconnected, you can now carefully remove the fuel pump from the fuel tank. Ensure you have a container or cloth ready to catch any residual fuel.

Note: It is important to work in a well-ventilated area when handling fuel and to wear appropriate safety gear, including gloves and eye protection.

Step 6: Proceed with installing the new fuel pump by following the above steps in reverse. Ensure all connections are secure before starting the engine.

Taking out the old fuel pump

To take out the old fuel pump from your 2002 Toyota Camry, first depressurise the fuel system. Open the gas cap, locate the fuse panel under the hood, and take out the relay "C/OPN". Then, start the engine and let the car run until it stops. Disconnect the negative battery cable.

Remove the rear seat from the car by lifting the front edge of the cushions and disconnecting the mounting bolt. Lift and remove the cushion, then pull up the seatback locks and lower the seatbacks. Remove the bolts that mount the seat in place.

Find and remove the service hole cover on the floor under the seat. This will expose the fuel pump. Take the electrical and fuel line connectors off the fuel pump, then remove the retaining bolts and withdraw the unit from the fuel tank.

Use a screwdriver to release the clips holding the fuel assembly support, then take off the rubber isolator and remove the filter for the fuel sock. Disconnect the electrical connector on the assembly top, and the fuel pump can be removed from the housing.

This process will give you access to the fuel pump so that you can replace it with a new one.

Installing the new fuel pump

To install the new fuel pump, first, place the new fuel pump on the assembly housing and connect it. Then, reconnect the electrical connector to the filter for the fuel sock, replace the rubber isolator, and place the fuel pump/sending unit back into the plastic support. Next, replace the unit into the fuel tank and bolt it in. Put the electrical connectors back on and reattach the fuel line. Finally, put the rear seats back in the car.

Now, you need to pressurize your Toyota Camry fuel system. You can do this by turning on the ignition for a few seconds. Turn it off for 10 seconds, and then repeat the entire “on” and “off” sequence from five to ten more times.

Reattaching the rear seat

To reattach the rear seat of your 2002 Toyota Camry, you will need to follow these steps:

• Place the rear seat cushion back into the car, ensuring it is securely locked into place.
• Reattach the mounting bolts that hold the seat in place.
• Lift up the seatback locks and raise the seatbacks.
• Secure the seatback locks.
• Place the rear seat pad back on top of the cushion.
• Reattach any wiring or clips that were previously disconnected.

Now that you have replaced the fuel pump and reattached the rear seat, you will need to pressurize the fuel system. Here's how:

• Turn the ignition on for a few seconds, then turn it off for 10 seconds.
• Repeat this sequence of turning the ignition on and off 5 to 10 more times.

This will ensure that your fuel system is pressurized correctly and your car is ready to drive.
