Replacing The Fuel Sending Unit In A '97 Voyager

The fuel sending unit in a 97 Plymouth Voyager is located in the fuel tank. To replace it, you will need to remove the fuel filler cap, disconnect the negative cable from the battery, drain the fuel tank, raise the vehicle on a hoist, and support the fuel tank with a transmission jack. You will then need to remove the bolts from the fuel tank straps, disconnect the fuel lines, and electrical connector from the fuel pump module. Finally, you can remove the old fuel sending unit and install the new one, ensuring that all connections are secure.

Disconnect negative cable from the battery

Disconnecting the negative cable from the battery is an important step when working on any electrical component in a car. Here is a detailed, step-by-step guide on how to do this specific task when replacing the fuel sending unit in a 1997 Plymouth Voyager:

• Safety First: Before beginning any work on your car, it is important to take the necessary safety precautions. Make sure you are wearing protective gear, such as gloves and eye protection. Ensure the car is parked on a flat, level surface, and engage the parking brake.
• Locate the Battery: The battery is typically located in the engine compartment of the car. Open the hood and identify the battery. It is usually a rectangular black box with two terminals, one positive (+) and one negative (-).
• Identify the Negative Cable: The negative cable is connected to the negative terminal of the battery, which is usually marked with a "-" sign or a black cover. This cable is typically black, but it can also be brown or dark blue.
• Disconnect the Cable: Once you have identified the negative cable, you need to carefully disconnect it from the battery terminal. First, loosen the nut or bolt that secures the cable to the terminal using the appropriate size wrench or socket. Do not let the wrench or socket touch any other parts of the car, as it could cause a short circuit. Then, carefully lift the cable straight off the terminal. Do not let it touch any metal parts of the car.
• Insulate the Cable: After the cable is disconnected, it is important to insulate it to prevent accidental contact with the battery terminal. You can use a piece of electrical tape or a cable insulator for this purpose. Wrap the tape around the end of the cable, making sure that no metal is exposed.
• Secure the Cable: Once the cable is insulated, make sure to secure it safely away from the battery. You can use a cable tie or a piece of wire to attach it to a nearby secure point. This will prevent the cable from accidentally falling back onto the battery terminal while you are working.

By following these steps, you will have safely disconnected the negative cable from the battery in your 1997 Plymouth Voyager, allowing you to proceed with replacing the fuel sending unit. Remember to take your time and work carefully to avoid any accidents or damage to your vehicle's electrical system.

Drain the fuel tank

To drain the fuel tank of a 97 Plymouth Voyager, follow these steps:

First, remove the fuel filler cap. This is important to do at the beginning to ensure your safety and avoid any spillage. Next, disconnect the negative cable from the battery. This will prevent any electrical current from flowing during the draining process. Now, insert a fuel siphon hose into the fuel filler neck and push it down into the tank. You will use this hose to drain the fuel. Make sure you have a suitable container to collect the fuel.

Once you have the hose in place, you can start draining the fuel tank. Ensure that you are in a well-ventilated area and be cautious to avoid any spillage or splashing. Continue draining until the tank is empty.

Now that the tank is empty, you will need to raise the vehicle on a hoist to access the fuel tank more easily. Use a transmission jack to support the weight of the fuel tank and prevent it from falling.

At this point, you can remove the bolts from the fuel tank straps to release the tank. Lower the tank slightly, just enough to access the connections and components you need to work on.

It is important to keep the work area clean and free of dirt or foreign material, so make sure to clean the area around the fuel tank module and tank before proceeding.

The next steps involve disconnecting the fuel lines and electrical connectors from the fuel pump module. Depress the quick connect retainers on the fuel lines with your thumb and forefinger to release them. Then, slide the fuel pump module electrical connector lock to unlock it, push down on the connector retainer, and pull the connector off the module.

Now you have successfully drained the fuel tank and disconnected the necessary components. You can proceed to the next steps of replacing the fuel sending unit, as outlined in the previous instructions. Remember to work carefully and consult a professional mechanic if you have any questions or concerns.

Remove bolts from fuel tank straps

To remove bolts from fuel tank straps in a 97 Plymouth Voyager, you will need to follow these steps:

Firstly, before beginning any work, remove the fuel filler cap and perform the Fuel System Pressure Release procedure. It is important to ensure that the fuel system is depressurised before proceeding.

Next, disconnect the negative cable from the battery. This will prevent any electrical current from flowing during the removal process.

Now, insert a fuel siphon hose into the fuel filler neck and push it into the tank to drain the fuel. It is important to drain the fuel tank completely into a holding tank or a properly labelled gasoline safety container.

Once the tank is empty, raise the vehicle onto a hoist and use a transmission jack to support the weight of the fuel tank.

With the tank secure, you can now begin to remove the bolts from the fuel tank straps.

After the bolts have been removed, lower the tank slightly, taking care not to strain the fuel lines or any other connected components.

Finally, clean the area around the fuel tank module and tank to prevent dirt and foreign material from entering the tank.

This process will allow you to safely remove the bolts from the fuel tank straps and proceed with the replacement of the fuel sending unit.

Disconnect fuel lines from the fuel pump

To disconnect the fuel lines from the fuel pump of a 97 Plymouth Voyager, follow these steps:

First, ensure you have performed the Fuel System Pressure Release procedure. Next, disconnect the negative cable from the battery. Insert a fuel siphon hose into the fuel filler neck and push it into the tank to drain the fuel tank. It is important to use a suitable container for the drained fuel.

Now, raise the vehicle onto a hoist and use a transmission jack to support the weight of the fuel tank. Remove the bolts from the fuel tank straps and lower the tank slightly. Clean the area around the fuel tank module and the tank itself to prevent dirt and foreign material from entering the tank.

Finally, you can disconnect the fuel lines from the fuel pump module. To do this, depress the quick-connect retainers with your thumb and forefinger.

Remove the fuel pump and its O-ring from the fuel tank

To remove the fuel pump and its O-ring from the fuel tank of a 97 Plymouth Voyager, follow these steps:

Firstly, remove the fuel filler cap and perform the Fuel System Pressure Release procedure. Disconnect the negative cable from the battery. Insert a fuel siphon hose into the fuel filler neck and push it into the tank. Drain the fuel tank into a holding tank or a properly labelled gasoline safety container.

Now, raise the vehicle on a hoist and use a transmission jack to support the fuel tank. Remove the bolts from the fuel tank straps and lower the tank slightly. Clean the area around the fuel tank module and tank to prevent dirt and foreign material from entering the tank.

Next, disconnect the fuel lines from the fuel pump module by depressing the quick connect retainers with your thumb and forefinger. Slide the fuel pump module electrical connector lock to unlock it. Push down on the connector retainer and pull the connector off the module.

Using a specialised tool, carefully remove the plastic locknut counter-clockwise to release the pump module. Finally, carefully remove the pump module and its O-ring from the tank.
