Turned out to be the main grounding strap to the battery. This would explain why the engine ran, but wouldn't start. The strap wasn't completely worn, but enough that it couldn't carry the current to start the engine, only run accessories.It sounds like an internal short or perhaps an open the ignition switch is creating. Can you yank the wiring and bypass the keyed switch and test?
Now on to why it won't start and run. I'm digging into the fuel pump next.
...and the battery was bigger than the one in my 2015 f150 ..f150 has a 750 cca and the little 1.5 in the cooper has an 800 cca ..and heavy !! ...go figure !!
