OK, I re-did a couple of tests on Bentley 24.20.

1. Disconnecting ECU connector, I connected ECU connector terminal 1 to ignition coil terminal 15. Got battry voltage. Then, still connected, I pinned center wire of Hall sender connector (at distributor) to ground. I heard a "click" in the distributor (my conclusion (right? or wrong?) is that the Hall sender in the distributor is OK?).

2. (this might be root cause) I ECU terminals 5 & 7 (O2 sensor). Supposed to get 0 ohms. I got about 50 to 70 ohms. What do you think? I disconnected the wire connector lead of the O2 sensor and retested and saw little change in the ohm reading. Reconnected the wire lead, same. 

Comments, please? Thank you.

Ps to Mark, yes, when I double-jumped the relay the fuel pump ran constantly.
