@Andystobbs,
I have disconnected the injectors and cranked the car, the HPFP only gets to about 50K hPa.

With the injectors disconnected, I powered the HPFP solonoid directly with a 9v battery. When I crank the car the fuel pressure quickly reaches max 250K hPa.

What controls the HPFP?
Is it the DME?

Does anyone know where I can get a wiring diagram for the E90 N43 Engine?
