Bump for pics of mysterious yellow switch, chasing a forever crank no starting issue myself. First started out as long crank and sometimes took two tries, now it won’t fire up after as many cranks as I try.

I don't have, not sure what sw either.
But, posting: Year, mileage and security light on or off. Helps diagnose.

Typically long crank to start, crank no start then crank start and eventually crank no start. Bad fuel pump.

I think this is what you guys are searching for. It’s near the OBD 2 connection
