Taking the approach of "what was changed" , you changed EC-2's (Tracy modified, and Bob White's unmodified) and you changed the wire going to the injector.
Try going back to plain wire to the injectors to eliminate the possibility of the wire having a problem. ???

Al,
I have two EC2's. Bob White sent me his to test against mine. The NOP is flashing on both and A/B processors too.
I have power to pins 33 and 34.
Spark plug / ignition test on Mode 8 works fine.
2 Serial leads have connectivity between EC and EM.
Since I have a second EC to swap, the EC is not a suspect.
During the Tracy's update I replaced the single wires to the injectors with two pairs of shielded 18 gauge I got at S&F.
I started suspecting the wire, since it has one blue and one white wire inside. The number on the wire is: 2112/202SJ-18 1F2Y2.
I thought it may be a some kind of resistor wire? But we tested resistance, and checked fine?
Thanks Al. Looks like I need dumb luck to get out of this one :)

Two things: Have you checked that the processor chip(s) are fully seated in
plug (base); and - is the behavior the same for both controllers?
If you have +12 power to pins 33 or 34, and you have the serial lead
connected to the EM2, and the processor in functioning, you should not see
NOP. Possibly something has happened in shipping or handling. If the
processor is not functioning of course you can not trigger the injectors.
Good luck,
Al
