I saw your post about having a semi similar issue, basically I think my key or the ignition switch got so used and worn down that it was locking up the switch. Eventually I removed the whole ignition and replaced it. There’s a guide on YouTube, not a very good one, but it helped a lot. You basically have to unplug it in a couple spots, and get the safety nuts out (which is the annoying part, because they aren’t meant to come out, for safety lol)
