Thanks, discnik for the code info; if you are able to forward the info from your other computer, I would appreciate it very much.
In the meantime, after having my car towed to a nearby service place, they
were able to get the car started by re-seating some of the relays under the dashboard. But a few hours after I drove home, the problem recurred. One
additional clue now is that while the code reader powers up from the car (I removed its battery), it cannot communicate with the control module.
