94 Sable hard start when hot

After many attempts I have established that there is a momentary
lapse in the SPOut signal. With no start condition I do get spark and
immediate start when SPOut connector is opened. To diagnose
whether it is PCM or harness seems to be too much trouble given
hard access to both and very intermittent nature of the problem.
So, if hot no start gets in my way I am going to switch to direct spark
control
by the ICM. Any comments or advice?

It'll be interesting to see, if you put a switch in spout, what happens
when you close it once you get the car started.
