So we had the mass air flow sensor replaced again with an after market one as ford doesn’t make the part anymore. The computer was replaced, we also replaced the batteries. Now it won’t start. Got it started after it wouldn’t turn over it just clicked. Finally started and it made a loud gear grinding sound, kind of like when you turn your key on but the car is already running? When the noise stopped the engine ran quiet. Turned it off but now it won’t start. It doesn’t even click. What could it be, were thinking the starter. Is that a reasonable conclusion?
