Wow!
A comprehensive informative question.
Points for you!
So,anyway,you've got jump leads,that's clear,
so take the black one,connect it to the battery neg- terminal and clamp the other end ON GOOD CLEAN ENGINE/GEARBOX METAL and retry.
What your doing is bypassing the engine/gearbox earth path,and if the fault is in there somewhere the jump lead will act as a new earth.
If there's any earth faults bypassing it will mean it will start.
Just to clarify,the jump lead isn't connected to any other car but yours,
Neg terminal then across to your engine,bypassed.
