Ok, this morning (thanx to Huw's sage advice, taking the time to answer
my newbie questions) I pulled the connector for the cold start valve and
looked for GROUND at the appropriate terminal - gr/wht wire IIRC -
during cranking.

I found ground for a *fraction* of a second when cranking first begins,
and then a relatively solid ground for a second or so when the car acts
as tho it is going to start, but no ground during actual cranking.  Does
this sound right?

Again, symptoms are crank, kinda-sorta attempt to fire, crank for time
eternal.  MUST stop cranking, sit, wait and repeat, each time w/improved
suceess until car will idle.  It's during the "kinda-sorta attempt to
fire" that I saw ground for the CSV.  Everything I've read seems to
indicate it should ground during cranking..........?

Of course I realize this is temp dependent; car had been sitting all
night, I'd say outside ambient temp was approx 50-55 degrees, but it
will exhibit the same "cold-start" symptoms after sitting for 4+ hours
in 90 degree heat.

Thanx for any replies, I'm determined to figure this out, 'cause if I
can't I won't keep the car, it nearly sends me into fits of rage when it
does this :(

Next step is to look at morning fuel pressure/fuel accumulator/check
valve as some have suggested.
