What to Do When the Fuel Pump Fails to Deliver Fuel and the Engine Won't Start?

Apply 12V power to the relay coil to check if the control circuit closes. If it does not close, replace the relay with a new one and recheck. During startup, observe whether the tachometer on the dashboard moves. If it does not move, the sensor is damaged and needs to be replaced with a new one. Try replacing the fuel pump with another one.
