AJ6 Engineering has a 6 page study which is worth reading. No Start conditions are explained.

I'd also have a quick read of Doug's excellent "Cranks but won't start" checklist, here:
ENGINE CRANKS BUT WONT START Series 3 XJ6
And since you have a parts car nearby, swap out the red pektron diode and the power resistor (DAC1211) on the RHS fender well...
I'm in NC too, near Salisbury...
