Probably missing the input when cranking due to reduced ouput voltage at cranking speeds.However it must eventually "see" the cam teeth to synchronise and then start.Once running most ECU's can lose the cam input and still run OK as they can use the crank sensor to sync off, so wouldn't worry too much.An autronic expert will probably now post and tell me this is all b******s, but that would be my un-educated guess...
