I haven't run my 240z for about 7 mths now due to a number of reasons, but when I did a few days ago a couple of things happened.... 1. The battery was stuffed and wouldn't turn over enough to pump gas through to the fuel filter. 2. In gear with the clutch in, turning over the starter motor rocked the car - as though the clutch was out! Some people have advised me to put it in gear, and rock the car back and forth with clutch in untill it breaks free. Is this good advice???
