So I went to start the mustang tonight to move it out of the garage. While turning over before starting I head a large squeal and then a small backfire through the carb possibly. Now when I try to start the car all it does is turn over, no attempt at firing or getting a spark. I checked all the plug wires, checked the belt. I have no idea what it could be. After repeated attempts to start the car I eventually flooded it, so I am waiting a bit before I try to start it again. Does anyone have any idea what this could be, I have never had a problem with this motor and its fairly new (4 years or so). Please help!
