Quick update.
She was still refusing to get out of bed, even after much angry prodding.
Found a loose earth strap from the block..Wasn't the problem, but wouldn't have been helping.
Changed plugs..nope.
The young Mechanic who has been helping me said 'check the lugs on the crank pully'..Rusty. 'And check the crank sensor'..Corroded.
Cleaned one, changed the other.
Boom...We have life.
Ok, it was a rumbly 3 cylinder life, as we now know the coil pack is toast as well, but we all did a little dance anyway.
