There are a few ways you can tell if you have a bad fuel pump. These are is the engine sputters at high speeds, vehicle loses power while accelerating, or the engine will not start.
If it become noisy or your vehicle becomes hard to start or stalls you may need a new pump. Replace the filter first. If the symptoms persist then a fuel pressure test will verify the condition of the pump.
Noisy fuel pump, stalling, or engine will not start and you have no fuel pressure.
Fuel pump will not run.
No, when you purchase a fuel pump you get only the fuel pump. The wiring that connects to the fuel pump is located on the vehicle and should not be removed when you remove the old pump.

Remove fuel tank from vehicle and then remove fuel pump from tank.
The fuel pump pressure sensor monitors the fuel pressure of the vehicle.
The vehicle will stop running and refuse to start. In most cases the pump either works or it don't. In some cases it can put out low pressure allowing the engine to only idle. It depends on make and model of your vehicle. Also if the fuel pump regulator is vacuum driven check vacuum line, what usually happens is the regulator diaphragm breaks inside the fuel regulator allow full fuel flow to the injectors causing severe flooding to the point where i have seen gasoline running out of the tail pipe, which will cause extreme engine damage. So pay attention to what the car symptoms are telling you.
