Changing the fuel pump on a 1992 Toyota Camry can be a moderately complicated job. The fuel pump is located inside the fuel tank, and can be accessed by removing the rear seat. The pump is a modular unit, and only the pump may need replacing rather than the entire unit. The tools required for the job include a wrench and a screwdriver, and the process involves disconnecting the negative battery cable, removing the rear seat cushion, and relieving the fuel pressure. The electrical fuel pump wiring can then be disconnected, and the pump bracket attaching screws, return hoses, and outlet pipe can be removed. It is important to check for any fuel leakage and to replace any sealing gaskets and rubber parts showing signs of deterioration.

What You'll Learn
Disconnect the negative battery cable
To disconnect the negative battery cable on your 1992 Toyota Camry, you will first need to open the car's hood and locate the fuse panel. Once you have found the fuse panel, look for the relay labelled "C/OPN" and remove it. This will help to depressurize the fuel system.
Next, start the car's engine and let it run until it stops. This will help to ensure that any remaining pressure in the fuel system is released. After the engine has stopped, you can then safely disconnect the negative battery cable. It is important to make sure that you only disconnect the negative cable, as disconnecting the positive cable could result in an electrical short.
Once the negative battery cable is disconnected, you can proceed with the next steps of removing the rear seat cushion and floor service hole cover to access the fuel pump. Remember to always work in a well-ventilated area when performing any fuel system repairs.

Remove the rear seat cushion
Step 1: Access the Rear Seat
Start by opening the rear doors of your Camry and identify the rear seat cushion. It is the bottom portion of the rear seat that you sit on. You will need to remove it to access the fuel pump located underneath.
Step 2: Remove the Rear Seat Cushion
Locate the hinges or levers that secure the rear seat cushion in place. Typically, there are metal hinges or plastic levers on both sides of the cushion. These can be locked in place, holding the seat cushion firmly. You will need to disengage these hinges or levers to release the seat cushion.
Use a flat-head screwdriver or similar tool to carefully pry open or push down the hinges/levers. Be gentle to avoid damaging the plastic or upholstery. Once disengaged, lift the rear seat cushion upwards and then pull it towards you to remove it from the car. There may be additional hooks or fasteners underneath the seat cushion that you will need to disengage as well. Ensure you check and unfasten any other securing mechanisms.
Step 3: Set the Seat Cushion Aside
Once the rear seat cushion is removed, set it aside carefully. Place it in a safe area where it won't be damaged or cause an obstruction. Make sure to also remove any other objects or debris that might be on or around the seat cushion, ensuring a clear workspace.
Step 4: Inspect and Prepare the Area
With the rear seat cushion removed, you now have access to the fuel pump area. Take a moment to inspect the space and identify any potential obstacles or issues. Look for any electrical connections, fuel lines, or other components that may need to be addressed when replacing the fuel pump. This step ensures you have a clear understanding of the task at hand and can plan accordingly.
By following these steps, you will safely and effectively remove the rear seat cushion of your 1992 Toyota Camry, providing the necessary access to replace the fuel pump. Remember to work carefully and consult a professional mechanic if you have any doubts or concerns.
