Replacing Fuel Pump In 2005 Ford Five Hundred: Step-By-Step Guide

If you're looking to replace the fuel pump on your 2005 Ford Five Hundred, you'll need to decide whether to do it yourself or take it to a mechanic. While it is possible to access the fuel pump by going under the back seat, it's recommended to have it done by a professional unless you are experienced and have the proper tools. The average cost for a fuel pump replacement across all vehicles is between $611 and $894, but prices may vary depending on your location and the specific model of your car. Before starting the replacement, make sure to release the fuel system pressure and disconnect the battery ground cable for safety.

Disconnect the battery ground cable

Disconnecting the battery ground cable is one of the first steps to take when changing the fuel pump on a 2005 Ford Five Hundred. Here is a detailed, step-by-step guide on how to do this:

Step 1: With the vehicle in neutral, position it on a hoist. This will give you access to the underside of the car, where the battery is located. If you do not have access to a hoist, you can try using jack stands to lift the car and provide the necessary clearance. Ensure the car is securely lifted and will not move or shift while you are working.

Step 2: Locate the battery. The battery is typically located in the engine bay, towards the front of the car, or in the trunk or rear of the vehicle. Refer to your owner's manual if you are unsure of the battery's location.

Step 3: Identify the battery ground cable. The ground cable is usually black and is connected to the negative (-) terminal of the battery. It is often secured with a clamp or bolt.

Step 4: Before disconnecting the cable, ensure you have the necessary tools, such as a wrench or socket set, to loosen and remove the clamp or bolt. You may also need a pair of gloves to protect your hands from dirt or any corrosive material on the battery.

Step 5: Once you are ready, loosen the clamp or bolt with your tool. Do not fully remove it yet.

Step 6: Carefully move the cable away from the battery terminal to avoid any accidental contact. Ensure the cable does not touch any metal parts of the car, as this could cause a short circuit.

Step 7: Completely remove the clamp or bolt that secures the cable to the battery terminal. Set it aside in a safe place, ensuring it does not roll away or get lost.

Step 8: Cover the exposed battery terminal with a piece of tape or a terminal cover to prevent accidental contact or arcing.

Step 9: Proceed with the next steps for changing the fuel pump, ensuring you follow safety precautions, especially when working with fuel and electricity.

Remember to reconnect the battery ground cable once you have completed the fuel pump replacement. This is critical for the electrical system of your car to function correctly.

Remove the rear lower seat cushion

To remove the rear lower seat cushion of a 2005 Ford Five Hundred, follow these steps:

First, make sure the vehicle is in neutral and then use a hoist to position the car. Next, release the fuel system pressure and disconnect the battery ground cable. Remove the fuel tank filler cap and set it aside. Insert a fuel drain tube into the fuel tank filler pipe until it reaches the fuel tank inlet spout. Attach a fuel storage tanker to the fuel drain tube to remove any residual fuel.

Now, you can release the fuel tank filler pipe hose clamp and disconnect the fuel tank filler pipe hose from the fuel tank. Insert the fuel drain tube into the fuel tank inlet spout and attach the fuel storage tanker to drain the fuel from the right side of the tank.

With that done, you can move on to removing the rear lower seat cushion. Release the latches and pull upward on the rear lower seat cushion to remove it.

Disconnect the fuel pump module electrical connector

To disconnect the fuel pump module electrical connector on a 2005 Ford Five Hundred, follow these steps:

First, locate the fuel pump driver module. It is located on the right-hand C-pillar at the bottom. You will need to remove the plastic trim to access it.

Once you have located the module, follow these steps to disconnect the electrical connector:

• Identify the electrical connector: It will be a plug or a wiring harness connected to the fuel pump module.
• Unplug the electrical connector: Gently pull the connector away from the module. You may need to depress a tab or release a locking mechanism to unplug it.
• Set the electrical connector aside: Place it in a safe location where it will not be damaged or accidentally reconnected.
• Prepare for fuel pump removal: With the electrical connector disconnected, you can now proceed with removing the fuel pump.

Note: These instructions are based on a standard vehicle configuration and may vary depending on your specific vehicle's make and model. Always refer to your owner's manual or a qualified mechanic for more detailed instructions.

Disconnect the fuel tank filler pipe hose from the fuel tank

Disconnecting the fuel tank filler pipe hose from the fuel tank is a crucial step in replacing the fuel pump of a 2005 Ford Five Hundred. Here is a detailed, step-by-step guide on how to perform this task:

Prepare the Vehicle:

• Ensure the vehicle is in a safe and well-ventilated area.
• Place the vehicle in neutral and position it on a hoist or jack stands.
• Release the fuel system pressure by following the manufacturer's guidelines.
• Disconnect the battery ground cable to prevent any accidental sparks.

Access the Fuel Tank Filler Pipe Hose:

• Remove the fuel tank filler cap to relieve pressure and set it aside.
• Insert a suitable fuel drain tube into the fuel tank filler pipe until it reaches the fuel tank inlet spout. This will help drain the fuel from the tank safely.
• Attach a fuel storage tanker to the fuel drain tube to collect the drained fuel.

Disconnect the Fuel Tank Filler Pipe Hose:

• Release the fuel tank filler pipe hose clamp using the appropriate tool.
• Carefully disconnect the fuel tank filler pipe hose from the fuel tank by pulling it away from the tank.

Clean-up and Safety:
