Hi All. Back on this one. Car wont start no spark, good inj/pulse,fuel pump active, scoped cam sensor & crank sensor ok, no square wavepattern at ign/amp when cranking, checked wiring to pins 112/113 at ecu ok. fitted genuine coil & amp assy, had ecu tested ok. Could it be the immobiliser coming in when cranking,when the car starts its ok and will run all day, its only when switched off and try to start again, thers no pattern it can be from cold or hot,just leave for a time and it then starts. Help please, really dont want to send to dealer. thanks john.
