My 2011 Ford Transit Connect has sporadic issue with starting after it sits. Have been able in past to start with a jump. replaced battery. Problem persists. 134k miles. I’m a total novice but would like help to pass on to mechanic. ( I have spent $$$ with 3 different shops trying to solve this). The car starts for them no problem so they say. But there it sits in my driveway. Immovable again.Advice much appreciated.
