Check if a fuel pump is working by first turning the key to the 'ON' position and listening for a hum near the fuel tank, which indicates the pump is priming. If silent, locate the fuel pump relay and fuse in the vehicle's manual and ensure they're not blown. Finally, use a fuel pressure gauge on the fuel rail to verify adequate pressure. Precaution: Perform these steps in a well-ventilated area and adhere to safety guidelines.
