Replacing Fuel Pump In Mitsubishi Galant: Step-By-Step Guide

If your 2000 Mitsubishi Galant is having trouble starting, you may need to replace the fuel pump. Before you do anything, ensure that the fuses and relays are working, and that the gas tank is less than a quarter full. The fuel pump is located under the back seat. To replace it, you will need to relieve the fuel system pressure and disconnect the negative battery cable, before removing the rear seat cushion and taking out the access cover. You will then need to unplug the fuel pump's electrical connection and disconnect the fuel send and return hose. Finally, remove the retaining cap for the fuel pump and install the new one.

Prepare your vehicle for service

To prepare your 2000 Mitsubishi Galant for a fuel pump service, there are several important steps to follow. Firstly, ensure that the gas tank is below a quarter full; this will make it much easier to manage the fuel tank assembly. Next, ensure proper ventilation by rolling down the windows, opening the hatch, and keeping your work area well-ventilated. Working with fuel can be challenging, so maintaining a safe and well-ventilated workspace is crucial.

Now, we can move on to the vehicle-specific steps. Disconnect the negative battery cable using a socket wrench to relieve the fuel system pressure. This is an important safety precaution. After that, remove the rear seat cushion. You can do this by pulling the seat stopper and lifting the lower cushion. With the rear seat cushion removed, you will be able to access the fuel pump area.

At this point, you should also remove the access cover. This will expose the fuel pump and its connections. Before proceeding further, it is recommended to mark the location of the black ring for proper reinstallation. This will ensure that you can correctly align the fuel pump assembly during reassembly.

Disconnect the negative battery cable

Disconnecting the negative battery cable is one of the first steps to take when changing the fuel pump on a 2000 Mitsubishi Galant. This is a crucial step to ensure your safety when working on any electrical components in your car.

To begin, locate the negative battery cable. It is usually black and connected to the negative terminal of the battery, which is often marked with a "-" symbol. Once you have located the cable, follow these steps:

• Gather your tools: You will need a socket wrench or a suitable tool to loosen and remove the cable.
• Loosen the cable connection: Use the socket wrench to loosen the nut or bolt that secures the cable to the battery terminal. Turn it in a counter-clockwise direction to loosen it.
• Disconnect the cable: Once the connection is loose, carefully remove the cable from the battery terminal. You may need to wiggle it gently to detach it.
• Insulate the cable: After the cable is disconnected, it is important to insulate the terminal to prevent any accidental electrical shorts. You can use electrical tape or a cable insulator cap for this purpose.
• Secure the cable: Ensure that the cable is secured safely away from the battery and any other metal components to avoid accidental contact. You can tie it down or use a cable tie to keep it in place.

By following these steps, you will have successfully disconnected and isolated the negative battery cable, making it safe to proceed with the fuel pump replacement or other maintenance work on your 2000 Mitsubishi Galant. Remember to exercise caution when working with electrical systems, and always refer to a qualified mechanic or a repair manual for specific guidance on your vehicle.

Remove the rear seat cushion

"Remove the Rear Seat Cushion:

First, you'll need to access the fuel pump module, which is located inside the vehicle, under the rear seat. Start by moving the front seats as far forward as possible to give yourself more room to work. Then, carefully pry off the plastic covers on the rear seat cushion's front edge; these are usually removed by hand. Be careful not to scratch the plastic or the surrounding upholstery. Once the covers are removed, you'll see two bolts on each side that secure the rear seat cushion to the floor. Use a socket wrench to loosen and remove these bolts. Set them aside in a safe place for reinstallation later. Gently lift and remove the rear seat cushion. Place it upside down on a clean surface, being careful not to damage the upholstery or foam. If your Galant has a fold-down armrest, you'll need to remove it as well. There are usually one or two bolts holding it in place.

The fuel pump access panel will now be visible. It is a metal cover located in the middle, towards the rear of the exposed floor. There may be additional trim pieces or panels that need to be removed, depending on your specific model. These are usually held in place with screws or clips and can be carefully pried off with a flat-head screwdriver. Ensure you keep track of which screws go where to make reassembly easier."

Unplug the fuel pump's electrical connection

To unplug the fuel pump's electrical connection on a 2000 Mitsubishi Galant, you will first need to prepare your vehicle for service. Ensure that your gas tank is below a quarter full; otherwise, you will have difficulty getting the fuel tank assembly back in.

Next, relieve the fuel system pressure and disconnect the negative battery cable with a socket wrench. Remove the rear seat cushion by pulling the seat stopper out and lifting the lower cushion. Now, you can remove the access cover.

At this point, you will be able to access and unplug the fuel pump's electrical connection. It is important to exercise caution and wear protective gear during this process, as you will be working with fuel and electrical components.

Once the fuel pump's electrical connection is unplugged, you can proceed to the next steps in the fuel pump replacement procedure.

Reinstall the fuel pump assembly

To reinstall the fuel pump assembly, you will need a second pair of hands to push down on the fuel pump assembly to keep it sealed into the gas tank. Ensure that the black grommet is pulled down to the bottom of the fuel pump assembly and that it fits around the lip of the gas tank. If this step is not done correctly, you will experience gas leaks.

Check that the triangle arrow on the fuel pump assembly is pointing towards the driver's side, as it was when you removed it. Push down on the fuel pump assembly and, if it moves up and down, you will need to give it another turn. If you are unable to match the arrow back up with the mark on the black plastic ring, the grommet is not seated properly and may be pinched.

Reattach the fuel lines and reconnect the electrical harnesses. Screw the lid plate back down over the hole. The fuel feed line should be properly clipped in, and the fuel return line should be all the way on with the hose clamp. Reinstall the seat, and do not forget to pull the seat belt locks up through the seat before locking it into the clips.
