The fuel pump is located inside the fuel tank of a 1998 Mercury Mystique. To replace the fuel pump, you will need to remove the fuel tank from the vehicle. This is a complex task and it is recommended to consult a qualified mechanic.

There is an access panel above the tank in the passenger compartment that can be used to reach the fuel pump. However, if there is no access panel, the fuel must be drained from the tank, and then the tank must be lowered from the vehicle to access the pump. This will require around 2.2 to 3.5 hours of labor, depending on the specific model of your Mercury Mystique and the complexity of the task.

The cost of replacing the fuel pump can vary depending on your location and the labor rate of the shop. The parts for a fuel pump replacement may cost around $100 to $300, while the labor can range from $273 to $994. It is always a good idea to get multiple quotes from different repair shops and compare prices before proceeding with any repairs.

Additionally, it is important to note that there may be an easy fix to your fuel pump issue. Before attempting any repairs, you should check the inertia switch located behind the hood release handle. Reach your finger through the hole in the floor lining and press the button of the switch inside the plastic hole. This will reset the switch if it is tripped.

The fuel pump can be accessed via an access panel in the passenger compartment

The fuel pump in your 1998 Mercury Mystique can be accessed and replaced without removing the fuel tank. There is an access panel located above the tank in the passenger compartment. This panel can be removed to access the fuel pump for replacement.

To replace the fuel pump, first ensure that power is cut to the pump to avoid any electrical supply issues. Then, remove the access panel in the passenger compartment. The fuel pump should be visible and accessible through this opening. Next, disconnect the fuel pump supply and return hoses, EVAP system hoses, and electrical connections to the pump. Once these connections are removed, the pump can be lifted out through the access panel.

If your vehicle has an in-line external fuel filter, it is recommended to replace the filter at this time. Before installing the new pump, check for any reusable brackets or pick-up screens that can be transferred from the old pump to the new one. Then, insert the new pump through the access panel and secure it in place. Reattach all the hoses and electrical connections that were previously removed. Finally, fill the fuel tank and run the engine to test for leaks.

It is important to note that some sources suggest that the fuel tank may need to be lowered or removed to access the fuel pump. However, this may not be necessary if an access panel is present in the passenger compartment.

If there is no access panel, the fuel tank must be lowered

If there is no access panel in your 1998 Mercury Mystique, you will need to lower the fuel tank to replace the fuel pump. Here is a step-by-step guide on how to do this:

Before removing the fuel tank, it is important to drain the fuel to reduce the risk of spillage during the removal process. Place a suitable container under the fuel tank and carefully drain the fuel by opening the drain plug. Make sure to dispose of the fuel safely and in accordance with local regulations.

Step 2: Lower the fuel tank

The fuel tank in a 1998 Mercury Mystique is typically secured by straps and fasteners. Loosen and remove these straps and fasteners to release the fuel tank. Carefully lower the fuel tank from the vehicle, taking note of any hoses or wires that may be connected to it. You may need to disconnect some of these connections to fully lower the tank.

Step 3: Access the fuel pump

With the fuel tank lowered, you should now be able to access the fuel pump. The fuel pump is located inside the fuel tank and is connected to the fuel lines and electrical system. Take note of how the fuel pump is connected so that you can properly install the new one.

Step 4: Remove the old fuel pump

Disconnect the fuel pump from the fuel lines and electrical system. This typically involves detaching hoses, clamps, and electrical connectors. Be careful not to damage any of the components during this process. Once the fuel pump is completely detached, remove it from the fuel tank.

Step 5: Install the new fuel pump

Take the new fuel pump and attach any reusable brackets or pick-up screens from the old fuel pump. Carefully insert the new fuel pump into the fuel tank, ensuring that it is securely connected to the fuel lines and electrical system. Refer to your vehicle's repair manual for specific instructions on how to connect the new fuel pump.

Step 6: Reinstall the fuel tank

Lift the fuel tank back into place and secure it using the straps and fasteners. Reconnect any hoses or wires that were previously disconnected. Ensure that all connections are secure and properly routed.

Step 7: Refill the fuel tank and test

Add fuel to the tank and start the engine to test for leaks. Check all connections again to ensure that there are no fuel leaks. If there are no leaks, your new fuel pump installation is complete.

Please note that working on fuel systems can be dangerous, and it is always recommended to seek the assistance of a qualified mechanic if you are unsure about any part of this process.

The fuel pump costs around $100-$300

The fuel pump supplies pressurised gasoline to the fuel injectors in the car's engine. It is powered by a compact electric motor. As with any electro-mechanical component, the fuel pump will degrade and fail over time. If the fuel pump is not working, the car will not start.

There are several symptoms that may indicate a failing fuel pump. These include the car stalling and failing to restart, the check engine light coming on, or a whirring noise coming from the fuel tank. If you experience any of these issues, you should replace the fuel pump as soon as possible.

When replacing the fuel pump, the mechanic will first test the pump to confirm that it is faulty. They will then remove the fuel pump from the tank through an access panel above the tank in the passenger compartment. If there is no access panel, the mechanic will first drain the fuel from the tank before lowering the tank from the vehicle to access the pump.

The mechanic will then remove the fuel pump supply and return hoses, as well as the EVAP system hoses and electrical connections to the pump. They will attach any reusable brackets and pick-up screens to the new pump before installing it. If the fuel system uses an in-line external filter, this will also be replaced. Finally, the mechanic will refill the tank and run the engine to test for leaks.
