I have already explained to you what it takes to fire an individual cylinder. You need good compression, static and running. You need fuel from the injector including power to the injector and make sure the injection is not failing. You need good strong constant spark at the plug. What are you not understanding here? What is your skill level too please? You have 3 questions open already for the same thing and JA frowns on that. I'm trying to help you here.
