To check a fuel pump, first, verify the car's fuse and relay related to the pump. Listen for a humming noise when turning the ignition key to the 'on' position, indicating the pump is working. Next, use a fuel pressure gauge, attach it to the fuel rail, and check if the pressure meets the manufacturer's specifications. If unsure or none of these steps work, consult with a professional mechanic for further diagnosis.
