Replacing The Fuel Pump In A 2002 Tacoma: Step-By-Step Guide

The fuel pump in a 2002 Toyota Tacoma is located inside the fuel tank and pumps fuel from the tank to the engine. When the pump goes bad, it stops pumping fuel to the engine, causing the car to not start. A bad fuel pump can also cause the engine to overheat. To replace the fuel pump, you will need to drain the fuel tank, remove the fuel lines, fender liner, inside bracket, and fuel tank. Then, you can remove and replace the fuel pump before reinstalling the fuel tank and all the components. The average cost for a Toyota Tacoma Fuel Pump replacement is between $852 and $939, with labour costs estimated between $158 and $200, and parts priced between $694 and $740.

Drain the fuel tank

To drain the fuel tank of your 2002 Tacoma, you will need a drain kit. Insert the hose into your tank, then pump the fuel to create a flow and watch it drain. This is the first step in replacing the fuel pump in your Toyota Tacoma.

The fuel pump is located inside the fuel tank, and it delivers fuel to the engine. When the pump goes bad, it stops pumping fuel to the engine, causing the truck to not start. Sometimes the pump can get weak, but not go bad, which will cause the truck to hesitate. If you're driving at a consistent speed and you notice your truck jerking or hesitating, this could mean your fuel pump has gone bad.

The fuel pump is a hardy piece of equipment, but it can occasionally fail. Signs of such failure include a car that won't start or stalls once it has started. Other times, the fuel flow can slowly become starved, causing the check engine light to come on. A mechanic will need to get to the failed pump through the top of the fuel tank via an access panel in the passenger compartment or by removing the tank from the vehicle.

It is important to note that working with the fuel system is dangerous, and there is a risk of fire. Take all necessary precautions and, if you are not very experienced in auto repair, it is recommended to leave this job to professionals.

Remove fuel lines

To remove the fuel lines from your 2002 Tacoma, you will need pliers and a wrench. There will be lines connected to the sides and the front of the tank. Use your pliers to slide off the hose clamps, and for some lines, you will need a wrench to remove the line nuts. There will be some fuel drainage, so keep a towel handy.

The fuel lines are connected to the fuel tank, which is held in place by two brackets. Once you have removed the fuel lines, you can then remove the bolts holding the tank in place. Place a jack under the tank and slowly lower it. Note that the top of the tank is still connected by an electrical harness, so lower it with caution.

The fuel pump is located on top of the fuel tank, so you will need to remove the tank to access it. Be sure to disconnect the battery before beginning this process to reduce the chance of a fire.

It is important to take all necessary precautions when working with the fuel system, as it can be dangerous. Always refer to a qualified mechanic if you are unsure about any part of this process.

Disconnect the battery

Disconnecting the battery is the first step in replacing the fuel pump in a 2002 Toyota Tacoma. Here is a detailed, step-by-step guide on how to do it:

Before you begin, ensure you have the necessary tools and safety equipment. In this case, you will need a box wrench and a brush. It is also recommended to wear gloves and eye protection when working with batteries.

Start by locating the battery under the hood of your Tacoma. You will see two cables connected to the battery terminals: a negative (black) cable and a positive (red) cable. It is important to identify these correctly, as the disconnection process should start with the negative cable.

Once you have identified the negative cable, use your box wrench to loosen the nut that secures the cable to the battery terminal. Turn the nut in a counter-clockwise direction to loosen it. If there is any corrosion on the terminal, use your brush to clean it off before proceeding.

After loosening the nut, carefully pull the cable off the terminal. Be gentle, but firm, as you do not want to cause any damage to the cable or terminal. Once the cable is disconnected, tuck it away from the battery and the positive cable. Ensure it cannot accidentally come into contact with the positive terminal or cable.

Now, move on to the positive (red) cable. Again, use your box wrench to loosen the nut securing the cable to the positive terminal. Turn the nut counter-clockwise to loosen it. As before, if there is any corrosion on the terminal, clean it off with your brush before proceeding.

Once the nut is loosened, carefully pull the positive cable off the terminal. Again, be gentle but firm, and ensure the cable does not snap or become damaged. Tuck the positive cable away from the battery and the negative terminal, just as you did with the negative cable. Ensure there is no risk of the positive cable touching the negative terminal or cable.

With both cables now disconnected, your Tacoma's battery has been successfully disconnected. You can now proceed with the next steps to replace the fuel pump. Remember to exercise caution and avoid any potential hazards, such as sparks, which could ignite gases inside the battery.

Remove the fuel tank

To remove the fuel tank from a 1996-2015 Toyota Tacoma, follow these steps:

First, ensure the fuel tank is drained using a drain kit. Insert the hose into the tank, pump the fuel, and watch it drain. Next, remove all the fuel lines connected to the tank. There will be lines attached to the sides and front of the tank. Use pliers to slide off the hose clamps, and a wrench to remove the line nuts. Keep a towel handy to deal with any fuel that spills or drips.

Now, remove the fender liner. Use a socket to remove the bolts, and a flat-head screwdriver to pop off the clips holding the bottom part of the liner. Push the liner out of the way. With the liner removed, you will see a bracket and hose on the rear driver's side. Remove the two bolts holding the bracket in place, then remove the bracket and the hose. Use a socket to remove the worm clamp, then slide the hose off.

The fuel tank is held in place by two brackets. Remove the bolts holding the tank in place, then place a jack under the tank. Slowly lower the jack once the tank is free. Be cautious, as the top of the tank is still connected to an electrical harness.

Removing the Fuel Pump

The fuel pump in a 2002 Toyota Tacoma is located inside the fuel tank. To remove the fuel pump, you will first need to drain the fuel tank using a drain kit. Insert the hose into the tank, pump the fuel, and watch it drain. Once the tank is empty, remove all the fuel lines connected to the tank. There will be lines on the sides and front, so use pliers and a wrench to remove the hose clamps and line nuts.

Next, remove the fender liner by unscrewing the bolts with a socket and using a flat-head screwdriver to pop off the bottom clips. This will reveal a bracket and hose behind the rear driver's side fender liner. Remove the bolts and bracket, and then remove the hose. The fuel tank is held by two brackets, so remove the bolts and place a jack under the tank to slowly lower it. The tank's top is connected to an electrical harness, so be cautious when lowering it.

Now you can remove the fuel pump. First, disconnect the electrical connection on top of the tank, and then remove the bolts holding the fuel pump assembly. Finally, pull the fuel pump up and off the fuel tank.

Installing the New Fuel Pump

Install the new fuel pump by first securing it with bolts. Reconnect the electrical harness and slowly raise the fuel tank back into place. Reinstall the two brackets, the driver's side line, and the bracket. Tighten the fender liner back into place, and then reinstall all the fuel lines. Finally, refill the fuel tank with the gas you drained earlier.
