My woman's car would not start up for her on a cold December day in Columbus, Ohio. I figured it was coming since she was complaining of the car cutting out while she waits at the traffic light. Anyway, I got the car home in the garage. I checked the battery & it is good. I REPLACED: 1)starter 2)camshaft sensor 3) front crankshaft sensor 4)6 new spark plugs 5) All 6 ignition coils. 6) Oil change. It is turning over but will not start. I have not changed the fuel pump, but I don't smell any odors that would indicate that. Why won't this car start?
