2011 vivaro 2.0 in for diagnostics.
Van was a crank no start.
No ecu communication.
All powers/grounds tested and found it was missing a 12v ecu supply.
Ecu relay located and found it the be missing a switched 12 ign supply so relay not switching on.
Wiring traced back and repaired.
Van now back up and running ready to get back to work 💪
Repaired with no parts required.
