BMW 330i no power to fuel pump regulator and sender, possible relay or battery issue on BMW 330i

Some BMW 330i owners report experiencing issues with no power to the fuel pump regulator and sender, which can stem from several potential causes. These include a defective fuel pump relay that fails to supply power to the pump, leading to operational failure. Additionally, battery issues, such as a dead or malfunctioning battery, can contribute to a lack of power to critical components. Some owners also find that a faulty Fuel Pump Control Module (ekpm) prevents power from reaching the fuel pump, while corrosion in electrical connections may disrupt the power supply from the Engine Control Module (ECM) to the fuel pump relay. To address these issues, it is recommended that owners check the fuel pump relay, verify the battery condition, inspect the Fuel Pump Control Module for faults, and clean any corroded electrical connections to restore functionality.
