I found an amazingly simple problem on my way to fixing this very issue. I thought the brain (ECU) had given up. I swapped in my spare, and viola, away we go. For about a day and a half. Then, it repeats. No start when hot.
  This second time, though, I looked at other things while I am trying to swap brains. I looked carefully at the contact points in the harness connector for the ECU. I found most of them were not shaped correctly any more. They would not spring closed on the ECU blade contacts reliably any more. Some of them even had evidence of arcing. A few minutes with a small screwdriver, bending them CAREFULLY back into shape, and it was fixed. And best of all, there have been no repeats since! While I was doing this, I also pulled the connector at the distributor, and found the same issues with those leads. I am not sure which set of contacts was actually having the problem, but neither is unhappy right now!

  Lastly.....one problem still exists preventing me from driving my
darling gray ghost, that lies in its inability to start when warm.
I've heard of this before, but have no idea where to start. It fires
right up, then i drive it.....then i shut it down.....and it wont
restart till it's totally cooled. I just replaced both Temp 1 and Temp
2 sensors. Fuel Pump? Fuel Pump Relay? I thought these cars were
incapable of vaporlock. Fires right up when cool.
