Firstly i'm no diesel expert. What are you using to read the codes and what are they. You say that all injectors come up open circuit that tells me either ECU has a faultHi
So what would you suspect at the moment that the issue may be ?
Thanks
or wiring from ECU to injectors has a problem. Is there any other codes that come up. Ideally Tech2 GM Midi or Opcom can be used for live data.
