>>> I was under the impression I should be getting a 12v supply to the injector which is earthed through the ecu to make the circuit?<<<
You are thinking petrol, and not diesel.
As others have said the ECU will not fire the Injectors before it sees a pre set rail pressure.
The operating voltage of the injectors will be anything from 60 volts up to 200 volts depending on system.
The amps ramp can exceed 20 Amps. HTH
