I see from the FSM where the oil pressure switch is located. I don't see anything that looks remotely like that on the car. Is it buried under the distributor? Need to be accessed from underneath? I don't have access to a lift at the moment. I'll see if I can source an ICM locally.
I gave it a 1 second burst of ether, then started the car. It fired right up and ran for a few seconds. So I think we've narrowed it down to the injectors not firing (also confirmed by the noid light).

see if one drawing it down
With vehicle in a nostart mode still measure injector resistance again just to be sure
Make sure still have power there too

Not sure I understand. You're saying to ohm the injectors again, but with the key in the run position?

Suggesting checking when in a failed condition. The Injectors shorted when hot in the video. Only saw low resistance when in failure mode.

I will do those and report back. Is this everything I need for a noid light? http://www.pepboys./oemtools-noid-li...169?quantity=1 I will need to run over there before they close.

A long overdue update... The car is finally fixed. I hate to have to turn things over to a professional mechanic, but after replacing all of the parts discussed in this thread, I still had no start. So I had to shell out to get it fixed, but I also learned some things...
The VATS unit itself had failed. He replaced it with this: https://newrockies.com/
Apparently, I am *supposed* to have a second horn under the hood specific to the security system. Mine was removed at some point in the life of the car... so when the VATS module failed, it was triggering the alarm, which didn't actually sound because the horn wasn't there.
So, I ended up spending a lot more than I needed to, between his labor, and all the unnecessary parts I replaced-- but there's a whole lotta new under the hood now, so hopefully I won't have any more serious problems for a while.
Thank you to all of you who contributed to this thread with advice and suggestions-- I really appreciate your help!
