Another suggestion is to install an "Otto-Start" type relay, which allows even a "sensitive" ignition switch to trigger the solenoid. Do a search for "Otto Start " (named after our own Otto Bartsch, aka tekenaar) but essentially it is just a standard relay (such as used in fog lights etc) that powers the solenoid directly from the battery or a fuse position on the fuse box, but only requires a few milliamperes of current through the ignition switch, which sounds like yours is capable of. If that doesn't work (and you should do it ANY event, as it's not IF but WHEN the contacts in the ignition switch fail, and the relay prevents that), I would start looking at the solenoid, or perhaps a bad engine ground, or...
