Replacing Axial Fuel In Toyota Matrix: Step-By-Step Guide

If you're looking to change the axial fuel in your Toyota Matrix, you may be referring to the fuel injectors or the fuel pump. The fuel filter is built into the fuel pump assembly, so changing the pump will also change the filter. You can access the fuel pump through an access hole under the rear bench seat. You can find step-by-step guides and video tutorials online to help you with this process.

Removing the fuel pump

The fuel pump is located inside the fuel tank of a Toyota Matrix. To access the pump, follow these steps:

First, park your car on a level surface and engage the parking brake. Then, locate the pump assembly in the fuel tank. You can do this by turning the key to the "ON" position and listening at the filler opening. The fuel pump should be audible for 2-3 seconds.

Next, find and verify the fuel pump relay and fuse. If the fuse is damaged, replace it with a new one of the same amperage. Once this is done, check the fuel pump's operation. If the pump is functioning correctly, the issue is resolved. If not, and the fuse and relay are working, check for power and ground at the fuel pump.

Now, relieve the fuel system pressure and disconnect the negative battery cable. Drain as much fuel as you can from the tank, and disconnect the filler fuel hose and the electrical connection to the old pump.

Support the fuel tank using a jack stand and a block of wood. Remove the entire pump assembly, including the pump and the fuel level sending unit, and carefully lower the tank.

Remove all hose clamps, disconnect the fuel line or fuel tank hose, and extract the old pump from the tank.

Comparison and Installation of the New Fuel Pump

Compare the new fuel pump to the old one to ensure you have the correct part. Once verified, install the new pump by connecting all the fuel lines. Reinstall the straps and bolts, and reconnect the filler fuel and electrical connector. Finally, reconnect the negative battery cable.

Post-Installation Testing

Fill the gas tank and conduct a road test to ensure the new pump is functioning correctly.

Note: It is highly recommended to get the clogged fuel filter changed when replacing the fuel pump to avoid further issues and the need for additional repairs.

Dismantling the fuel pump

To dismantle the fuel pump of a Toyota Matrix, you will need to first locate the pump assembly in the fuel tank. The fuel tank does not have to be removed as there is an access hole under the rear bench seat. After removing the rear bench seat, you can remove the cover and access the fuel pump.

Next, relieve the fuel system pressure and disconnect the negative battery cable. Drain as much fuel as possible from the fuel tank and disconnect the filler fuel hose and the electrical connection to the old pump.

Support the fuel tank using a jack stand and a block of wood. Remove the entire pump assembly, including the pump and the fuel level sending unit, and lower the tank. Remove every hose clamp, disconnect the fuel line or fuel tank hose, and extract the original pump from the gas tank.

Once the old pump is removed, you can then install a new fuel pump by connecting every fuel line and reinstalling the straps and bolts.

Replacing the fuel filter

The fuel filter in a Toyota Matrix is built into the fuel pump assembly, which is located inside the fuel tank. To replace the fuel filter, you will need to remove the rear bench seat to access the fuel pump. Here is a step-by-step guide on how to replace the fuel filter:

Step 1: Remove the Rear Bench Seat

Locate the rear bench seat of your Toyota Matrix and remove it by unscrewing the bolts or releasing the latches holding it in place. Once removed, set the seat aside in a safe place.

Step 2: Access the Fuel Pump

Under the rear bench seat, you will find a cover that provides access to the fuel pump assembly. Remove this cover to access the fuel pump.

Step 3: Remove the Fuel Pump

The fuel pump assembly is located inside the fuel tank. To remove it, you may need to disconnect any wiring or hoses connected to the assembly. Be careful not to spill any fuel during this process and have a suitable container ready to collect any fuel that may spill.

Step 4: Dismantle the Fuel Pump

Once the fuel pump assembly is removed, you can proceed to dismantle it carefully. This process may vary depending on the specific model of your Toyota Matrix, so it is recommended to refer to a repair manual or seek assistance from a certified mechanic.

Step 5: Replace the Fuel Filter

With the fuel pump assembly dismantled, you should now be able to access and replace the fuel filter. Make sure to purchase a compatible fuel filter for your vehicle. Install the new fuel filter according to the manufacturer's instructions or seek guidance from a professional.

Step 6: Reassemble and Reinstall the Fuel Pump

After replacing the fuel filter, carefully reassemble the fuel pump assembly following the reverse steps of the disassembly process. Reinstall the fuel pump assembly into the fuel tank and secure it in place.

Step 7: Reinstall the Rear Bench Seat

Once the fuel pump assembly is back in place, you can now reinstall the rear bench seat. Make sure to secure it properly and reconnect any necessary wiring or components.

Step 8: Final Checks

After completing the replacement, start the engine and check for any fuel leaks. Ensure that all components are securely connected and functioning properly. If you notice any issues, refer to a certified mechanic for assistance.

Please note that working on fuel systems can be dangerous, and it is essential to take the necessary safety precautions. Always refer to your vehicle's repair manual or seek professional assistance if you are unsure about any steps or procedures.

Replacing the fuel injectors

Step 1: Purchase the Right Fuel Injectors

Before you begin, make sure you have the correct fuel injectors for your Toyota Matrix model. You can check this by consulting the owner's manual or by seeking advice from a mechanic or auto parts store.

Step 2: Locate the Fuel Injectors

The fuel injectors in a Toyota Matrix are located in the engine, attached to the fuel rail.

Step 3: Prepare the Work Area

Park your car on a level surface and engage the parking brake. Wear protective gear, including gloves and eye protection, and ensure the engine is switched off and cooled down.

Step 4: Disconnect the Battery

Disconnecting the battery will prevent any electrical issues during the replacement process.

Step 5: Remove the Fuel Rail

The fuel rail is held in place by two retainer bolts. Loosen and remove these bolts, being careful not to drop them into the engine bay. With the bolts removed, carefully lift the fuel rail, taking care not to damage the injectors or any other components.

Step 6: Remove and Replace the Fuel Injectors

With the fuel rail removed, you can now access the fuel injectors. Gently twist and pull the injectors to remove them, taking note of their orientation for reinstallation. Install the new fuel injectors in the same position and ensure they are securely seated.

Step 7: Reinstall the Fuel Rail

With the new fuel injectors in place, carefully reposition the fuel rail and secure it with the retainer bolts. Ensure the bolts are properly torqued to avoid any fuel leaks.

Step 8: Reconnect the Battery

Reconnect the battery and ensure it is properly secured.

Step 9: Start the Engine and Check for Leaks

Start the engine and check for any fuel leaks around the injectors or the fuel rail. If no leaks are present, your replacement is complete.

Tips and Troubleshooting:

• It is recommended to replace the upper and lower injector seals when installing new fuel injectors, as they are non-reusable and can be a common source of leaks.
• Use a lubricant, such as spray silicone, to help seat the new seals and prevent pinching.
• If you experience a fuel leak after replacement, check that the fuel rail bolts are properly torqued and that the injectors and seals are undamaged and correctly installed.
• Always refer to your owner's manual or seek advice from a qualified mechanic if you are unsure about any part of the replacement process.

Locating the fuel pump reset button

To locate the fuel pump reset button in your Toyota Matrix, first check your owner's manual. If you do not have access to the manual, you can try looking in a few other places.

One source suggests that the Toyota Matrix is not equipped with a fuel pump reset switch. However, another source suggests that the fuel pump reset button can be found in one of two places.

The first place to look is in the trunk, behind the fabric on either the left or right side. The second location is near the passenger side kick plate under the dashboard. You may need to remove the panel to access the button.

If you have a 2006 Toyota Matrix, the fuel filter is built into the fuel pump assembly, which is located inside the fuel tank. There is an access hole under the rear bench seat. You can remove the cover, take out the fuel pump, and replace the fuel filter.
