Update

Worked through the collective list as methodically as possible. Everything
seems good (confirmed spark and injectors again) except that I could not
get a resistance reading on the rotor (replaced it) and two plug wires had
v. low resistance so I replaced them with used ones that I had (not great,
but better than the two that were in).
Good news is that she fired up and ran, albeit a little on the rough side.
Also, both the battery and oxygen sensor red idiot lights did not
extinguish as they usually do after increasing the rpms. A little light
(pun intended) reading tonight, then we'll see what tomorrow brings.
Will order the NGK BP6ET 3 pronged plugs, and new rotor, distributor and
plug wires.
Should probably get a backup coil and fuel pump as well, since we all know
there will be a 'next time'.
I will put together everyone's suggestions under separate heading so that
those who wanted a copy will have one.
Not completely finished yet, but feel much better now that she has started
and run again.
Thank you, as always, to the many of you who sent suggestions my way, and
especially Dan N. for his time and efforts.
Greatly appreciated. It's nice to be part of this group.
