Thanks for the reply Steve,i carried out your suggestion but there is no audible chime.LCD screen just informing me that system is in "economy mode",tried wake up procedure several times but with no joy.Would i be right in thinking that the system should come out of econ mode once the engine has started? Prob being of course the engine will crank but wont start due to no spark,Marelli ecu still logging p0606-ecu/pcm processor.Unable to get car in the workshop at the moment due to workload and the weather has not been great in manchester,so working outside not an option,will try to get it indoors on Tue and do some further checks.
