The fuel system is Bosch EDC 15 C7 Common rail. IMV control no pressure reg.
I carried out the pressure test using the non-intrusive "Frank Massey method"
Take out all fuel consumers i.e. the injectors by disconnecting the cam and crank sensors and then the injectors for good measure.
Disconnect the IMV this defaults to full flow hence pressure, crank engine and scope fuel pressure sensor voltage (it got up to 700mv). It should go to max pressure 4v+
