Message I was driving my 1990 300Z TT that has 107K miles on it the other day, stopped and turned off car. After five minutes, I went to restart car and the starter just clunked. I tried a couple more times and it did it again. I thought what the hell it's never done is before. The battery is new so I thought maybe it's the battery connection. I was stopped on a slight hill and didn't have any tools with me so I pushed in the clutch, turned on the key and got rolling fast enough to pop the clutch in third gear and rear tires lock up. ok needs higher gear so I tried 4th, got going again popped it and it did same thing. by now i'm running out of my hill. I put it in 5th and tried again, same thing. I pulled off the road to a safe parking area. I sat in the car thinking the wheels should have been turning. I sat there trying to think who am I going to call. I get out and open the hood and look for anything obvious and found nothing. I got back in the car, started clicking the starter and after about 5 or 6 tries the engine started turning over and started up with a noise like metal piece or piece's were loose. I immediately turned the motor off, thinking the worst. By now my friend shows up. I explained the problem to him, restarted the car and he listened. He heard the noise coming from the rear of the engine block, possibly the clutch or starter area. I let the car run for 2-3 minutes, the oil pressure was ok and the noise went away. I turned off the car and let it sit for 2-3 minutes. Restarted again and it made the same clattering sound upon start-up and then stopped so I decided to drive it home, about 8 miles without any problems. Gauges read normal. I parked the car and let it cool down for the day. The next day I started it up and it made the same clattering noise but went away in less than 5 seconds. I have not driven it since. Listening to the noise on start-up I think it could be the starter, flywheel, clutch or possibly a turbo?? But I don't think the turbo would lock the differencial... would it? I would appreciate ANY suggestions on how to troubleshoot.
