2012 BMW X5 35d M57 diesel

Post by Hberwald »

Crank no start/stall. Error codes show bank 2 injectors disabled. It will start, run for a couple seconds and then the DME shuts down the fuel.

I have replaced the injectors, had the DME tested on another car, and all is good.
I believe I am loosing fuel pressure. Data PID shows that the fuel pump is running at about 75% of requested speed. Wondering if I have a bad pump rotor winding as no fuel pump codes present.

I don't want to throw parts, like the HPFP and Pressure sensors, volume control valve, etc.
Any collective thoughts?
