Have someone get under the car with a long reach screwdriver or other prodding device and a hammer and hit the hammer while someone else tries to key on. I had the same problem a few months ago where my starter died, stranded me in a parking lot only to have upon a key turn, one relay click and nothing else. I thought it was the clutch switch so I put a paper clip in there and same thing. Had to call for backup in the form of a friend with a hydraulic lift, jack stands, hammer, and a long reach screw driver. It worked to get it home that night. The next morning I parked on a upper portion of my neighborhood and was able to bump start it to get it to the garage where my best friend changed the starter for me.
