My 1998 Civic Sedan Won't Start.......Not always, just every once in a while. This began about a month or so ago and has not indicated a pattern of consistency. Four or five times starting took a hold on the key and pumping of the gas pedal and when it did start seemed to struggle to find a smooth point for a moment. Then it would run fine the rest of day, week. Question: Could a fuel filter be causing this? Could there be a need to clean injectors? At the moment, for the first time, it won't start at all.
