Replacing Fuel Pump In 2001 Ford Ranger: Step-By-Step Guide

Replacing the fuel pump on a 2001 Ford Ranger can be a tricky task. The fuel pump is located inside the fuel tank, and there are two ways to access it: by dropping the fuel tank or removing the truck bed. The latter is usually the easier option for DIY mechanics. Once the fuel tank is accessible, the pump is held in place with a large threaded plastic nut, which needs to be carefully loosened to avoid damage. It is also important to keep the area clean and free of dirt and debris to prevent any contamination of the fuel tank.

The fuel pump replacement process involves several steps, including disconnecting the battery, fuel lines, and electrical connections, as well as removing and reattaching various components. It is recommended to replace the fuel filters at the same time as the fuel pump to ensure optimal performance and prevent future issues.

The cost of replacing a fuel pump can vary depending on the vehicle and the location. The average cost for a Ford Ranger fuel pump replacement ranges from $1,513 to $2,106, with labor costs between $186 and $234, and parts priced between $1,328 and $1,872. However, some people choose to perform this task themselves to save on labor costs, which can be significant.

Diagnosing a bad fuel pump

Firstly, check for any basic issues that might be causing the problem. This includes checking fuses, relays, the emergency fuel cut-off, and the anti-theft cut-offs. It is also important to check for a good spark, which can be done easily.

If the basic issues are not the cause, the next step is to check the fuel pressure. Turn the key forward and listen for the pump to prime. It should run for 5 to 20 seconds. If the pump is turning on, the next step is to check the fuel pressure at the rail. There is a Schrader valve on the fuel rail similar to the valve on a tire, which can be hooked up to check the pressure. It should be over 30 psi.

If the fuel pressure is low, the fuel pump may be faulty. Another indication of a bad fuel pump is the absence of any noise or priming when the key is turned.

To further diagnose and confirm a faulty fuel pump, a voltage test can be performed. A multimeter can be used to check the voltage at the fuel pump connector. If the voltage is low, the inertia switch may be the issue. The voltage at the inertia switch can also be checked to confirm this.

Additionally, the fuel pump relay can be removed, and a voltage test can be performed by manually controlling the system. If the pump starts spinning and you hear fuel, the fuel pump is likely faulty.

Before concluding that the fuel pump needs to be replaced, it is important to also check the electrical connections leading to the fuel pump and ensure they are intact.

By following these steps, you can accurately diagnose a bad fuel pump in a 2001 Ford Ranger and determine if it needs to be replaced.

Removing the truck bed

To remove the truck bed of a 2001 Ford Ranger, you will need to first remove the tailgate. This can be done by unbolting the two Torx-T45 bolts from the tailgate support and removing the tailgate. Next, unhook the tail lights from the wiring harness by crawling under the truck and looking under the rear bumper.

If you have a bed liner, you will need to remove it. Make sure to unhook the three 6mm bolts that secure the fuel filler neck. There are six bolts that secure the body to the frame. These bolts have a Torx T-55 bolt head. It is recommended to soak these bolts in a penetrant such as PB Blaster a day before removal to help loosen them. An impact gun or cheater bar can also be used to help remove the bolts.

Once the bolts are removed, you will need to enlist the help of another person to lift off the truck bed, as it is awkward and heavy, weighing around 150-200 pounds. With the truck bed removed, you will now have access to the fuel tank and can proceed with replacing the fuel pump.

Disconnecting the battery

Before starting, make sure you have gathered the necessary tools and safety equipment, such as gloves and eye protection. It is also recommended to refer to the owner's manual of your vehicle for specific instructions and safety precautions.

Locate the battery: The battery in a 2001 Ford Ranger is typically located in the engine compartment, near the front of the vehicle. Open the hood and identify the battery, which is a rectangular unit with two terminals, one positive (+) and one negative (-).

Identify the negative terminal: The negative terminal will have a "-" symbol or a black cover. It is important to always disconnect the negative terminal first to avoid any potential sparks or short circuits.

Loosen the negative battery cable: Using an appropriate-sized wrench or socket, loosen the nut or bolt that secures the negative battery cable to the terminal. Do not let the wrench or socket touch any metal parts of the vehicle to avoid creating a spark.

Disconnect the negative cable: 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. If possible, cover the terminal with a piece of electrical tape or a plastic bag to prevent accidental contact.

Secure the negative cable: Move the negative cable away from the battery and secure it in a safe place. Ensure that it does not touch any metal parts of the vehicle.

Repeat for the positive terminal: Following the same steps, loosen and remove the positive (+) battery cable from the positive terminal. Again, ensure that the cable does not touch any metal parts of the vehicle.

Check for any signs of corrosion: With the cables disconnected, inspect the battery terminals for any signs of corrosion or damage. If there is corrosion, you can clean it using a mixture of baking soda and water and a wire brush.

Store the cables safely: Place the disconnected cables in a secure location away from the battery to prevent accidental contact.

Mark the cables: To make it easier when reconnecting the battery, you can mark the positive and negative cables with tape or tags to identify which is which.

At this point, the battery is successfully disconnected, and you can proceed with the next steps of replacing the fuel pump. Remember to exercise caution and follow safety procedures throughout the entire process.

Disconnecting the fuel lines

Before beginning, it is important to gather the necessary tools, including a Ford Fuel Line disconnect tool (in 1/4th and 3/4ths sizes) and a hammer. These tools will be essential for safely detaching the fuel lines without causing damage.

First, locate the fuel lines. They should be connected to the fuel pump, which is typically located inside the fuel tank. If the fuel tank is still in the vehicle, you may need to access it through an opening in the passenger compartment or by removing the tank. Ensure you are in a well-ventilated area and take precautions to avoid any potential sparks.

Next, carefully disconnect the fuel lines from the fuel pump. This step requires the use of the Ford Fuel Line disconnect tool. Insert the tool into the fitting and depress the locking tab. This will allow you to separate the fuel line from the fuel pump without damaging the connection. Perform this step for both the 1/4" and 3/4" fuel lines.

Once the fuel lines are disconnected, gently pull them away from the fuel pump. It is important to be cautious during this step to avoid spilling any fuel. Use a shop-vac or absorbent towels to clean up any spilled fuel immediately.

After detaching the fuel lines, it is crucial to cap or plug the open ends to prevent dust, dirt, or other debris from entering the fuel system. This will help ensure that no contamination occurs during the rest of the fuel pump replacement process.

Finally, set the disconnected fuel lines aside in a safe location, away from any potential sources of ignition. Label the fuel lines to ensure proper reconnection during the reassembly process.

Remember to work cautiously and deliberately when handling fuel lines, as they contain flammable fuel. Always take the necessary precautions to avoid any potential hazards. By following these steps, you can successfully and safely disconnect the fuel lines when replacing the fuel pump in your 2001 Ford Ranger.

Removing the old pump

To remove the old pump from your 2001 Ford Ranger, you will need to first disconnect the battery to reduce the risk of fire. Next, access the pump by removing the truck bed or dropping the fuel tank. The pump is held in place with a large threaded plastic "nut", which you will need to loosen and remove carefully with a plastic mallet and a blunted chisel. Be sure to keep the area clean and clear of debris as you work. Once the "nut" is removed, you can lift out the pump and fuel level sensor. Be sure to drain any remaining fuel back into the tank before disposing of the old pump.
