The fireing is directly controlled by the ECU, outside of that the only other wireing is a common power supply and earthing system.

sorry looks like the ECU may have died s:( :( s:(

The result of swapping the coils and plugs was that the fault didn't move so it can't be any of them. Was hoping that it would be somthing like the crank sensor or cam sensor.

Was it definately a rebuilt engine and not an exchange? I know there are problems with import engines using UK ECU'S.

Everytime we swap an engine we use the same ECU that came with it.

It was definitely re-build, I oversaw the build and have all the old parts.
The ecu has been sent away for testing/repair.
I will post the result for anyone else stuck in the future.
Thanks for the help Guys
