Replacing Fuel Pump In 2007 Toyota Yaris: Step-By-Step Guide

If you're experiencing issues with your 2007 Toyota Yaris' fuel pump, it's important to get it checked out by a professional. While it is possible to replace the fuel pump yourself, it's a moderately complicated job that requires disconnecting the battery and accessing the pump through the top of the fuel tank or by removing the tank from the vehicle. The fuel pump in your 2007 Yaris is located inside the fuel tank, and you can access it through the back seat. There are several signs that indicate a failing fuel pump, including a car that won't start or stalls after starting, a check engine light turning on, or a whirring sound coming from the fuel tank. If you notice any of these issues, it's best to take your car to a mechanic or a dealership's service department as soon as possible.

Disconnect the battery to reduce the chance of a fire

Disconnecting the battery is an important safety precaution when working on the fuel system of a car, such as the 2007 Toyota Yaris. This is because a spark could occur while the gas tank is open, which could lead to a fire.

While some people may argue that disconnecting the battery is unnecessary as long as there is no key in the ignition, it is still a good idea to take this extra step to reduce the chance of a fire. This is especially true if you are working in an area where there may be other sources of electricity or sparks, such as a garage with power tools.

To disconnect the battery, locate the battery in the engine bay of your 2007 Toyota Yaris and remove the negative cable first, followed by the positive cable. Be sure to wear protective gloves and eyewear when handling the battery, and always exercise caution when working with electricity.

Additionally, you can simply unplug the wiring harness for the fuel pump, which is located next to the connector for the rear ABS. This will ensure that there is no power going to the fuel pump during the replacement process.

By taking these precautions, you can help ensure that you are working on your vehicle safely and reduce the chance of a fire or other accidents.

Remove the back seat to access the fuel tank

To remove the back seat of a 2007 Toyota Yaris to access the fuel tank, follow these steps:

First, remove all items under the storage hatch by unlocking them. Note that the spare holder protrudes above the relatively flat back. You will see that the seat frame is held on by four external Torx nuts, with two more under the bottom seat. The bottom seat frame is connected by two bolts, but these do not need to be removed to take out the seat.

Instead, use a pair of pliers or a screwdriver to press in the tabs holding the seat cushion to the bottom seat frame. Be careful not to force this step, as it is different from a Scion bottom seat and can rip if forced.

After removing the seat cushion, you will see two more Torx bolts that screw through the back seat frame to the bottom seat frame. Remove these bolts, and then pull out the seat. Finally, replace the bolts, and you will have access to the fuel tank.

Note that there is another protrusion with a cable coming out, likely the gas tank, which may need to be cleared to install a deck.

Drain the fuel tank

To drain the fuel tank of a 2007 Toyota Yaris, you will need to locate the fuel pump, which is inside the fuel tank. The fuel pump is accessible through an access panel in the passenger compartment or by removing the tank from the vehicle.

Before beginning any work, it is important to disconnect the battery to reduce the chance of a fire. This is a critical step as working with the fuel system is dangerous and proper precautions must be taken.

Once you have located the access panel, you will need to remove it. In some cases, you will need to drain the fuel from the tank before removing the access panel. This is a necessary step to prevent fuel from spilling out when the panel is removed.

After the access panel is removed, you can begin the process of draining the fuel tank. Place a suitable container under the tank to collect the drained fuel. Be extremely careful during this process as fuel is highly flammable and can pose a serious safety hazard if not handled properly.

Use a siphon pump or a similar tool to carefully remove the fuel from the tank. Ensure that the container you are using is approved for storing flammable liquids and is large enough to hold the amount of fuel in the tank.

During the draining process, be cautious of any sparks or open flames in the area. Avoid smoking or using any electrical tools that could create a spark. It is recommended to have a fire extinguisher nearby in case of any accidents or emergencies.

Once the fuel tank is drained, you can proceed with the next steps of replacing the fuel pump. Remember to dispose of the drained fuel properly and according to local regulations.

Remove the access panel

To remove the access panel of your 2007 Toyota Yaris to reach the fuel pump, you will first need to disconnect the battery to reduce the chance of a fire.

The fuel pump in a 2007 Toyota Yaris is located inside the fuel tank, but you can access it without removing the tank. Instead, you can reach it by going through the back seat. There will be an access cover that you need to remove. In some cases, you will need to drain the fuel before removing the access panel.

Once the cover is off, you can replace the pump and pre-pump filter screen. Be sure to take all necessary precautions to avoid starting a fire when working with the fuel system.

Disconnect the fuel lines and remove the old pump

To disconnect the fuel lines and remove the old pump from your 2007 Toyota Yaris, you will need to follow a few important steps to ensure a safe and effective procedure. Here is a detailed guide:

Step 1: Safety First

Before starting, it is crucial to prioritise safety. Working with the fuel system can be hazardous, so take all necessary precautions to prevent fires. Disconnect the battery to minimise the risk. It is also recommended to work in a well-ventilated area and wear appropriate protective gear, including gloves and eye protection.

Step 2: Accessing the Fuel Pump

The fuel pump in your 2007 Toyota Yaris is located inside the fuel tank. Fortunately, you won't need to remove the entire tank to access it. Instead, you can reach it by removing the rear seat and locating the access cover at the top of the fuel tank. This will be your entry point for replacing the fuel pump.

Step 3: Disconnecting the Fuel Lines

With the access cover removed, you will now be able to see the fuel lines connected to the pump. Carefully disconnect these fuel lines, ensuring that you have a container or absorbent material ready to catch any spilled fuel. It is important to perform this step cautiously to avoid any fuel spills or leaks.

Step 4: Removing the Old Fuel Pump

Once the fuel lines are disconnected, you can proceed to remove the old fuel pump. It is usually held in place with bolts or clamps. Loosen and remove these fasteners carefully, making sure not to drop them into the fuel tank. Gently lift out the old fuel pump and set it aside.

Step 5: Cleaning and Inspection

Before installing the new fuel pump, take this opportunity to clean the area around the fuel pump and inspect for any signs of damage, corrosion, or debris. Ensure that the fuel tank is free from any dirt or debris that may have accumulated. This step is crucial to prevent any issues with the new fuel pump and to ensure a proper seal.

Step 6: Prepare for Installation

With the old fuel pump removed and the area cleaned, you are now ready to install the new fuel pump. Refer to the manufacturer's instructions for the new fuel pump to ensure a proper installation. Have any necessary tools and materials ready before proceeding.

Remember to dispose of the old fuel pump properly or recycle it at an appropriate facility.
