How does the ECM calculate and control the fuel pump operation on 2008 BMW X3?

On the N52 engine, the ECM calculates the amount of fuel required at any given moment, activating the electric fuel pump as needed. The total volume required is transmitted as a message to the EKP control module via PT-CAN, which then converts this message into an output voltage to control the fuel pump. This pump can deliver up to 95 liters (25 gallons) per hour at a pressure of 5 bar (72.5 psi). To troubleshoot fuel system faults, begin by checking the fuel pump control module (EKP), with the EKP module fuses located in the power distribution box (A41).
