Welcome! You've done well to check/replace what you have using the search forum, so I don't think anyone will point you in that direction. <img src="/forums/images/graemlins/kewl.gif" alt="" />

My suspect would be the ignition switch rear half - a replaceable electrical portion with a short pigtail harness. They're fairly cheap from the dealer - $25 or so - and the replacement takes only a few minutes. I'd try that next.

There are also a couple of connectors on the passenger side inner fender.... IIRC one is for the coil lead. You could try separating those connectors, cleaning with spray contact cleaner (Radio Shack) and cycle the connection a few times to get a better contact.
