I wrecked my '00 GT last week, and I tried to start the motor. It turns over just fine, but I think the car has some kind of fuel shut off when in a collision. Anyhow, when I tried to start it, the starter would not engage the flywheel. It just spun. After a few tries, it screeched very loudly. It did this a few more times, and finally engaged fully and turned the motor over. I think the flywheel may be damaged. If the flywheel is damaged, I might ask the shop that is repairing my car if I can pay the difference between the price of a stock replacement flywheel and the Ford Racing Lightweight aluminum flywheel, and have them install it as part of the repair process. I wanted to know if anyone has installed one, and what they think of it? My motor is a Windsor motor, with the eight bolt crank, if that makes any difference.
