Hope this helps.
My 92 (gen II) has had a similar problem since the day I bought it. Jiggling the key would usually be enough to get it to start. When I'd go to start it, all the lights worked properly, as did anything battery operated, but the engine did nothing. It seemed like the starter switch and guess what? It eventually wouldn't start at all, no matter how much I jiggled the switch, or how fast I turned the key (don't laugh--that worked the best). Called up Ken Garff Mitsubishi in Salt Lake and had them send me a new starter switch. Remove the lower portion of the steering column, the lower part of the dash, and slapped it in. It took 2 seconds once the steering column cover was removed to install. No problems since!!! Hope this helps. <img src="/forums/images/graemlins/kewl.gif" alt="" />
