1. so it is running (albeit not perfectly) on its own fuel supply?
2. IIRC the start circuit runs through the fuse box and ...
3. So does the fan circuit and ...
Those fuse boxes are horrible, as are the fuses.
It's a pain but I'd recommend a "fuse box service". IIRC it's not to
hard to get it hanging free under the dash. Then, one thing at a time,
remove or unplug everything (connectors, relays, fuses...), clean with
contact cleaner (and/or a pen eraser), add a dab of dielectric grease,
You'll also see the red/black wire going in and out of it and can test
your start circuit there.
Look up the rad fan circuit and look for its wires, too.
