clutch pedal problem no resistance

Could be one of a couple of problems. One, your clutch return spring could be broken. Two, you could have a bad master or slave cylinder. Three, you may have a clutch issue that will require replacement of the clutch itself. Have this checked out, without more info it's impossible to narrow down your problem.

Possibly a broken clutch cable ( earlier fox chassis Mustangs) Newer cars use a hydraulic clutch , so it could be a leaking master or slave cylinder , or the master cyl is low/empty of fluid . The system could have air in the hydraulics , dirt, or the wrong fluid...all of which can cause pedal problems.
