99 Mazda Miata clutch problem

The clutch pedal went to the floor when I tried to start the car. The resevior was empty, so I refilled it, and tried pumping clutch pedal, so I could bleed line, but had same problem. I then unhooked metal line at Clutch master cylinder. Again pumped the pedal and the fluid barely came out. Removed cylinder, and used a rachet extention to push the piston and fluid squirted out. I still replaced it with a new cylinder but I still have the same problem. Is the rod under the dash connected to the the pedal need to be adjusted so it pushes farther into the cylinders piston? Open to suggestions please.
