I just had this problem, its an easy fix but it'll be uncomfortable. If you look underneath where your clutch is. At the very top where the clutch pivots there is a small pin switch. When you step on the clutch, a little metal plate presses down on the switch and the car cranks up. I was able to turn on the car just by pressing on that pin with my finger w/out touching the clutch. Its hard to see and you need to crawl on your back. The sensor is mounted to a flat plate that has two 14mm bolts on each side, i just took a small 14mm wrench and loosend it up a but, which moved the sensor out a bit. So now when I step on the clutch that little pin gets fully pressed and starts every time now. Sorry I couldn't get a better picture.
