also check to see if you have induction from the inlet manifold as you could have a blockage
also worth looking at engine temp sensor in live data and test mass air flow
also check for supply to injectors and ecu signal/trigger to injectors there is also within the ecu live data immobilizer on or off and engine rpm
there is a separate earth from the ecu to the engine on some and i dont suppose the cam chain may have jumped was it rattling.
