Problems arose tonight, the engine won't engage the clutch! Unless the gear is selected before starting the engine. When I got the car running in first I could get it into gear if selected with force. Oh and also the fuel tank is leaking like crazy!! Helppppppppp

Are you sure it isn't brake fluid leaking?

Fuel line had come off, doesn't explain the clutch though :-S

If it will go in gear with the engine off, won't go in gear with engine running then it's either the clutch itself or it's hydraulics.
