Replacing Fuel Pump In 2007 Dodge Caliber: Step-By-Step Guide

Changing the fuel pump on a 2007 Dodge Caliber is a complex process that requires a range of tools and expertise. The fuel pump is located under the back seat and can be accessed by removing the rear seat cushion and a plastic cover. It is important to release the fuel system pressure and disconnect the battery before beginning any work. When removing the fuel pump, it is crucial to avoid spilling fuel inside the vehicle. The pump should be drained, and any reusable parts should be transferred to the new pump. The new pump should be properly located in the tank to ensure the fuel gauge works correctly. Before completing the installation, it is recommended to test the pump by connecting the terminal and turning the key to hear the pump run for a few seconds.

Removing the rear seat cushion

To remove the rear seat cushion of a 2007 Dodge Caliber, follow these steps:

Firstly, perform the Fuel System Pressure Release procedure. Next, remove the air cleaner lid, disconnect the inlet air temperature sensor, and detach the makeup air hose. Then, remove the negative battery cable. Now, you can remove the rear seat cushion.

After removing the rear seat cushion, you will see a plastic cover. Remove this, and clean the top of the fuel tank to remove any loose dirt and debris.

At this point, you will be able to access the fuel pump, which is located on the top of the fuel tank.

Disconnecting the negative battery cable

• Park your car and engage the parking brake: Find a flat, paved, or concrete surface to park your car. It is important to find a level surface to ensure your car remains stable while you work. Engage the parking brake to prevent accidental movement.
• Locate the negative battery cable: Open the hood of your car and locate the battery. The negative battery cable is usually black and marked with a minus (-) symbol. It is connected to the negative terminal on the battery.
• Prepare the necessary tools: You will need a few basic tools to disconnect the negative battery cable safely. These include a pair of gloves to protect your hands, a wrench or socket that fits the battery terminal, and a clean cloth or towel.
• Put on your safety gloves: Before you begin, put on a pair of gloves to protect your hands from dirt, grease, and any potential electrical hazards. It is always important to prioritize safety when working on your car.
• Loosen the negative battery cable: Using the appropriate wrench or socket, loosen the nut or bolt that secures the negative battery cable to the terminal. Turn it in a counter-clockwise direction to loosen it. Do not remove the cable yet.
• Disconnect the negative battery cable: Once the nut or bolt is loosened, you can now carefully disconnect the negative battery cable from the terminal. Gently lift or wiggle the cable free. It is important to only disconnect the negative cable to maintain the car's electrical system.
• Secure the cable: With the negative cable disconnected, you need to ensure it doesn't accidentally touch any metal parts of your car, which could lead to a short circuit. One way to do this is to attach the cable to a fixed part of the car, away from the battery. You can use a cable tie or a piece of tape to secure it. Alternatively, you can place the cable on the car's body, ensuring it doesn't touch any metal components.
• Cover the battery terminal: Use a clean cloth or towel to cover the exposed negative terminal on the battery. This will prevent accidental contact and provide an additional layer of protection against short circuits.

By following these steps, you will have successfully disconnected the negative battery cable on your 2007 Dodge Caliber, ensuring a safer environment as you proceed with changing the fuel pump. Remember to reconnect the cable properly once you've completed the fuel pump replacement.

Locating the fuel pump

First, remove the rear seat cushion to access the area under the back seat, where the fuel pump is located. It is important to note that the fuel pump is usually placed under the back seat of the vehicle.

Next, remove the plastic cover to expose the fuel tank. Before proceeding, clean the top of the tank to remove any loose dirt and debris.

Then, use a special tool, such as #9340, to remove the left side module lock ring. This will provide access to the fuel pump, which is located on the top of the fuel tank. It is important to note that the pump's position relative to the tank is crucial for the fuel gauge to function correctly.

At this point, you should be able to see and access the fuel pump for further maintenance or replacement. Remember to exercise caution and refer to safety guidelines when working with fuel systems.

Removing the fuel pump

To remove the fuel pump from a 2007 Dodge Caliber, first remove the rear seat cushion and plastic cover. Next, use a dull chisel and hammer to tap out the retaining ring. Unhook the lines, being careful not to spill fuel inside the vehicle. Lift out the pump, and tip it so that the gas pours back into the tank.

Before removing the fuel pump, it is important to release the fuel system pressure and disconnect the negative battery cable. It is also recommended to clean the top of the tank to remove any loose dirt and debris. Additionally, it is important to note that the pump must be properly located in relation to the tank for the fuel gauge to work properly.

Once the pump is removed, it is important to drain the fuel from the fuel pump module and not spill any fuel inside the vehicle.

Installing the new fuel pump

To install a new fuel pump in your 2007 Dodge Caliber, you will first need to purchase a suitable replacement. There are several options available online and through automotive retailers. Once you have acquired a new fuel pump, you can proceed with the installation process as outlined below:

Step 1: Accessing the Fuel Pump

Before beginning any work, ensure that you have released the fuel system pressure and disconnected the negative battery cable for safety. Next, remove the rear seat cushion and locate the plastic cover above the fuel tank. Clean the top of the tank to remove any dirt or debris. Then, use a special tool (#9340) to remove the left side module lock ring and carefully pull the fuel pump module out of the fuel tank. Ensure that you do not spill fuel inside the vehicle.

Step 2: Draining the Old Fuel Pump

Drain the fuel from the old fuel pump module. Again, be careful not to spill fuel inside the vehicle.

Step 3: Preparing the New Fuel Pump

Before installing the new fuel pump, it is recommended to perform a quick test. Connect the fuel pump terminal and turn the key in the ignition to hear the pump run for 2-3 seconds. This will ensure that the pump is functional and that the sending unit is making the fuel gauge work.

Step 4: Installing the New Fuel Pump

With the new fuel pump prepared, carefully lower it into the fuel tank. Ensure that the pump is properly located and positioned according to the fuel tank markings. Secure the fuel pump in place using the retaining ring, making sure it is tapped all the way in.

Step 5: Reassembling the Components

Once the new fuel pump is securely in place, you can proceed to reassemble the components in the reverse order of removal. Reattach any hoses, electrical connections, and the plastic cover. Reinstall the rear seat cushion.

Step 6: Final Checks

After completing the installation, refill the fuel tank and start the engine to check for any leaks. Ensure that the fuel gauge is functioning correctly and that there are no unusual noises coming from the fuel pump area.
