Alright guys, this is for my friend. His car is NOT a mustang BUT it is a MArk8 with the 4v motor in it. Here is the story. He went to rent a movie and when he left, he started the car, put it in reverse and backed out of the parking spot. As soon as he put it in Drive the car died. Now it will not crank at all. turn the key, nothing. try to jump it, nothing. No lights work, no radio, nothing. Battery terminals are clean, cables are connected, all fuses are good, and battery will spark when touched to conductor. What gives? Any suggestions on how to get his thing running again?
