My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
If you have not had a compression test done this should be done to see if the cylinder is low on compression due to a mechanical fault.I would also have the fuel injector tested to see if it is faulty needing replaced as well or cleaned.
Thanks Pete
