Hi again .

I was checking diesel pressure regulator valve located on high pressure pump. With ingition on voltage supplied is 9.55V, once ignition switch off it jumps to 12V for one second and then drops again to 9.55V and stays like that till main relay cuts off power .

Is this voltages corect ?

Can anyone​ post wiring diagram for ECU , thanks

If an injector is leaking it can lower the common rail pressure and inhibit starting. What injector fault were you thinking of?

Well i was suprised that when you disconnect injector (power plug) lexia doesn't register any fault . Example 'injector cylinder 1 not plugged in ' or similiar .

Anyone knows what correct voltages suppose to be on pressure regulator valve?
