Replacing Fuel Pump In '96 Corolla: Step-By-Step Guide

If you're experiencing issues with your 1996 Toyota Corolla, you may need to replace the fuel pump. Unlike larger vehicles, you won't need to remove the fuel tank to access the pump, which is located inside the car, underneath the rear seats. Before attempting any repairs, it's important to disconnect the negative battery cable and relieve the fuel system pressure. Once this is done, you can access the pump by removing the bottom of the rear seat and opening the service hole in the rear floor. From there, you'll need to remove the bolts holding the fuel tank set plate and take out the fuel pump assembly. This process can be completed in approximately 1.5 hours without the need for any special tools.

How to Change a Fuel Pump in a 1996 Toyota Corolla

Removing the rear seat cushion

To remove the rear seat cushion of a 1996 Toyota Corolla to access the fuel pump, follow these steps:

First, make sure you have the key removed from the ignition. For added safety, disconnect the positive end of the battery terminal. Next, pull on the left and right sides of the center front portion of the rear seat cushion to remove it. Angle the seat cushion out, pushing the seatbelt connectors through the cushion openings.

Now that the cushion is removed, you will be able to see the access panel for the fuel pump. The access panel is a circular stamped sheet metal cover that is fused to the body of the car with semi-adhesive glue. Gently pry around the cover with a large screwdriver until there is enough space to insert a knife and cut through the glue, separating the cover from the body of the car.

With the access panel removed, you will now have access to the fuel pump module and can proceed with the next steps to replace the fuel pump, as outlined in the previous response. Remember to exercise extreme caution when working on any part of the fuel system due to the high pressure involved.

Accessing the pump module

To access the pump module of a 1996 Toyota Corolla, you will need to remove the rear seat cushion. This is done by lifting it up to release the clips on each side and then pulling it out. Be sure to remove the key from the ignition first, and for added safety, disconnect the positive end of the battery terminal.

Once the rear seat cushion is removed, you will expose a service hole in the rear floor. This will allow you to access the fuel pump module, which is stored inside the fuel tank. Unlike larger vehicles, you won't need to remove the fuel tank to replace the pump.

Before accessing the fuel pump, it is important to relieve the fuel system pressure and disconnect the negative battery cable with a socket wrench. Wait at least 90 seconds before proceeding further.

Now you can begin to remove the components that secure the fuel pump module in place. Take out the bolts that hold the fuel tank set plate to the fuel tank. Then, remove the fuel pump assembly, which includes the fuel pump and the fuel level sending unit.

At this point, you will have successfully accessed the pump module and can proceed with replacing or repairing the fuel pump. Remember to exercise extreme caution when working on any part of the fuel system due to the high pressure involved.

Disconnecting the battery

To disconnect the battery, first locate the negative battery cable. This will be attached to the battery, which is usually located in the engine bay. Once you have located the cable, use a socket wrench to loosen the connection and detach the cable from the battery. Set the cable aside, ensuring that it does not touch any metal surfaces, as this could cause a short circuit.

It is important to note that you should wait at least 90 seconds before proceeding with any other steps if your vehicle is equipped with an airbag. This will ensure that you avoid any potential issues or complications.

Additionally, if you are planning to work on any other electrical systems in the car, it may be a good idea to also disconnect the positive end of the battery terminal for added safety. This will completely disconnect the battery, ensuring that there is no power running to any of the car's electrical systems.

By taking these steps to disconnect the battery, you will help ensure that you can safely work on the fuel pump and any other necessary repairs or maintenance.

Removing the pump module

To remove the pump module of a 1996 Toyota Corolla's fuel pump, follow these steps:

Firstly, remove the car's rear seat cushion by lifting it up and pulling to release the clip on each side. Then, remove the fuel pump's access cover. This may be secured by butyl tape, in which case you will need to pry it off, or it may be secured by four screws, in which case you will need to remove these with a screwdriver.

Next, unplug any electrical connectors on the pump module. Then, disconnect the fuel lines. To do this, release the fitting for the return line with a pair of needle-nosed pliers and slide out the retaining clip for the pressure hose. Loosen the module's large screw-on ring with water pump pliers or a special tool from an auto parts store. On older models, you may need to remove mounting screws instead.

Now, withdraw the assembly with the fuel pump and fuel level sending unit from the fuel tank. Release the clips for the plastic support at the bottom of the pump with a screwdriver to remove the support. Then, disconnect the rubber isolator, sock filter clip (using a screwdriver) and electrical connector. Finally, remove the fuel pump from the module's main housing. Check the condition of the strainer and replace it if it is dirty.

Installing the new fuel pump

To install the new fuel pump, first, attach the rubber cushion and clip, ensuring they are securely in place. Then, insert the new fuel pump into the module's main housing, following the manufacturer's instructions for the specific make and model of your Corolla.

Next, reconnect the fuel lines and electrical connectors. Ensure that the connections are secure and correctly aligned. Following this, place the module back into the fuel tank, tightening the ring or fastening the screws to secure it in place.

After this, close the access cover to the pump and reinstall the rear seats. Finally, reconnect the negative battery cable.

You may need to turn the ignition switch to the 'On' and 'Off' positions repeatedly to re-pressurize the fuel system.
