Years ago I had a clutch cable go and from memory similar circumstances. I pushed the pedal to change gear and thought 'That felt weird' then one or two pushes later it broke. It's possible, that like mine, your cable had worn down to a few strands and stretched. Those few strands possibly got you into first gear, then snapped. It's possible you have a break between the pedal and the actuation lever. Luckily, changing a Fulvia clutch cable is a very easy job, thanks to Lancia bringing the clutch actuation arm up to the top of the engine and not buried away as usual. From memory, there's a simple clip holding it to the pedal, feed it up through the conduit to the engine bay and attach. Keeps your nylon insert that fits into the arm because that doesn't come with the new cable (if that's the problem). If you fit one, adjust the cable tension by turning the large wing nut on the end. Adjust it so that you have 5mm of free play at the actuation arm, not constant tension. Good luck.
