Too bad he dosen't have a point distributor to drop in for a minute . he would at least know if the wiring harness , ballast , and cranking voltages were ok .
Like i said in previous posts, this looks to be ECM issue.
There is only one thing I can think of that has not been addressed .......is it possible that the ignition switch housing is worn and when in starting mode he has the key twisted beyond the contacts and that only the starter is cranking and no ignition? But isn't the ignition being fed from the relay ?

I don't know whats wrong why this car is not starting and I see no reasons why it won't at present time and what been tried .

This is not rocket science, i know its difficult for someone who is just learning but for us seniors who have 40 -50 yrs at this stuff, it bugs me to no end .
