Fuel pump is not working. Need instructions on how to install new fuel pump

Has the filter ever been changed? Need to know year and model of the truck. Fuel filters can be near the tank or under the hood. Filters are usually separate from the fuel pump.

This fuel punp is not removed by dropping the take like so many. It is under an access panel under the rear seat. To change the fuel pump follow these instructions.
1. Determine which fuel pump your Mitsubishi Galant will need. This depends not only on the make and model, but also the engine size.

2. Prepare your car for service to the fuel pump. Relieve the fuel system pressure and disconnect the negative battery cable with a socket wrench. Take out the rear seat cushion. You will need to pull the seat stopper out and lift up the lower cushion. You can now remove the access cover.
3. Unplug the fuel pump's electrical connection and disconnect the fuel send and return hose. Remove the retaining cap for the fuel pump with tool MB991480 and remove the fuel pump.
4. Install the packing material on the fuel tank. Replace it if the packing material is damaged or deformed. Install the new fuel pump and align the marks on the floor pan and fuel pump.

5. Complete the installation by reversing the removal procedure.

how can you tell if its the fuel pump is gone?

You didn't state if it was fuel injection or regular carb type.
If fuel injection, you have to drop the gas tank. Undo bolts on tank straps, lower slowly, disconnect the fuel lines and the wire connector for the pump. Make sure surface is clean, take a screw driver and hammer and tap the pump assembly locking ring until it's loose. Remove pump assembly. Installation is just reverse.
If it is carb type, the pump is on the drivers side of the engine.
Disconnect the fuel lines, take off the two bolts, remove pump.
To install that pump you need a pair of needle nose pliers to hold up the push rod while you are installing the new one. Hope this helps.

its pretty basic....remove 2 strap bolts....lower tank a little.....disconnect hoses and wires and lower the rest of the way
