Replacing Fuel Pump In 2002 Mazda Tribute: Step-By-Step Guide

The fuel pump in your 2002 Mazda Tribute is responsible for delivering gas from the fuel tank to the fuel injectors. If you're experiencing a loss of engine power, or your car is failing to start, it may be time to replace the fuel pump. This is a job best left to the professionals, as working with the fuel system can be dangerous and there is a risk of fire.

You can buy a fuel pump for your Mazda Tribute online or from auto parts stores, with prices ranging from $59.49 to over $1,000.

Disconnect the battery

Disconnecting the battery is the first step when replacing a fuel pump. This is a crucial safety measure that reduces the chance of a fire. Before you begin working on your Mazda Tribute, make sure you disconnect the battery. This will ensure that there is no power flowing to the vehicle's electrical system, minimising the risk of sparks or electrical shorts that could potentially cause a fire.

It is important to locate the battery in your Mazda Tribute. It is usually found in the engine bay, near the front of the vehicle. Once you have located the battery, you will need to identify the negative terminal, which should be labelled clearly and connected to the negative cable. The negative terminal will also have a black cover, in contrast to the positive terminal's red cover. Ensure that you disconnect the correct terminal to avoid any potential issues.

To disconnect the battery, you will need to loosen the nut or bolt that secures the negative cable to the terminal. You can do this using a wrench or socket that fits securely over the nut or bolt. Make sure to wear protective gloves to avoid any potential burns or sparks. Once the nut or bolt is loosened, carefully remove the cable from the terminal. Ensure that the cable does not touch any metal parts of the vehicle to prevent accidental electrical shorts.

After disconnecting the battery, it is a good idea to secure the cable to prevent it from accidentally falling back into place. You can use a cable tie or tape to hold the cable away from the battery. Additionally, cover the terminal with a piece of tape or a plastic bag to provide extra protection. By taking these precautions, you can ensure that there is no power flowing through the electrical system while you work on replacing the fuel pump.

Remember to follow safety guidelines and wear appropriate protective gear when working on your vehicle. It is always better to be cautious when dealing with electrical systems and flammable liquids to minimise the risk of accidents or injuries.

Remove the access cover

To remove the access cover, you will first need to disconnect the battery to reduce the chance of a fire. This is an important safety precaution to take before proceeding with any further steps.

Next, locate the access cover. This will be found on the fuel tank, where the technician can access the pump and pre-pump filter screen. In some cases, you will need to drain the fuel before removing the access panel. This is an important step to avoid spilling fuel when removing the cover.

Once the cover is off, the pump can be replaced.

Replace the pump and pre-pump filter screen

To replace the pump and pre-pump filter screen on a 2002 Mazda Tribute, you'll first need to relieve the fuel system pressure. You can do this by running the engine and pulling the fuel pump relay, causing the engine to stall. Alternatively, with the engine off, you can press the Schrader valve on the pressure line momentarily, releasing a small spray of fuel.

Next, locate the fuel tank and remove it from the vehicle. This process will vary depending on your specific model, and you may need to use a jack to support and lower the tank. Once you've accessed the tank, take note of the fuel line connections and wiring before removing the old pump. Pay attention to the following steps to ensure a safe and successful fuel pump replacement:

• Before removing the old pump, it is recommended to clean the area around it to prevent dirt and debris from falling into the fuel tank.
• Drain the fuel tank or reduce the amount of fuel inside to minimize the risk of spills and make the tank lighter and easier to handle.
• When removing the old pump, make sure to take note of and carefully detach all fuel line connections and wiring.
• Be cautious not to let the tank hang by any hose or wire, as this can cause damage.
• After removing the old pump, install the new fuel pump and pre-pump filter screen, ensuring all connections are secure.
• Reassemble the fuel system and test the new fuel pump to ensure everything is functioning correctly.

It is important to work in a well-ventilated area when performing this task, as fuel vapors are highly flammable and toxic. Always wear safety gear, such as gloves and eye protection, to shield yourself from fuel spills and splashes. Additionally, if your fuel pump has a filter, consider replacing it at the same time as the fuel pump.

Check for leaks and other issues

When replacing the fuel pump on a 2002 Mazda Tribute, there are a few things to keep in mind to ensure that the repair is successful and safe. Here are some detailed instructions on checking for leaks and other issues:

Before beginning any work on the fuel pump, it is crucial to disconnect the battery to reduce the risk of fire. This is an essential safety precaution that must not be skipped.

If the fuel pump is located inside the fuel tank, you will need to remove the access cover to reach it. In some cases, you may need to drain the fuel before removing the access panel. With the cover off, proceed to replace the pump and the pre-pump filter screen.

If the fuel pump is located outside the fuel tank, the process is slightly different. You will need to disconnect the fuel lines and then remove the pump. Once the old pump is out, install the new one and reconnect the fuel lines.

After replacing the fuel pump, it is important to check for any fuel leaks or odors. Be vigilant during this step as fuel leaks can be dangerous and can lead to fires or explosions. If you notice any leaks or smell gasoline, do not start the car, and do not park it inside a garage or covered structure. Instead, have the car towed to a repair shop for further inspection and repair.

In addition to checking for leaks, you should also pay attention to the engine's performance after the repair. A properly functioning fuel pump should deliver the right amount of fuel at a high enough pressure to keep the engine running smoothly. If you experience issues such as loss of engine power, stalling, or difficulty starting the car, there may be another problem with the fuel pump or a related component.

It is also recommended to replace the fuel filters at the same time as the fuel pump. Clogged fuel filters can strain the fuel pump and affect its performance. Additionally, on some vehicles, the fuel pump relay may be prone to failure, so it is good practice to replace it when replacing the fuel pump.

Finally, keep in mind that working with the fuel system can be dangerous due to the risk of fire. Unless you are very experienced in auto repair, it may be best to leave this repair to a professional.

Clean the fuel tank

To clean the fuel tank of your 2002 Mazda Tribute, you will need to purchase a fuel tank cleaning kit. Delphi, the manufacturer of the Delphi Fuel Pump DFG0969, recommends using the FFC01 kit to clean the tank.

Before you begin, disconnect the battery to reduce the chance of a fire. Then, drain the fuel from the tank. Once the tank is empty, you can begin cleaning it with the kit. Be sure to also clean the cover, the outside, and the inside of the tank. Replace the old strainer and fuel pipe, and refill the tank with clean standard fuel from a gas station.

Fuel tank contamination is the leading cause of premature fuel pump failure, so it is important to clean your tank regularly.
