I've replaced all 18 wires from the EC2 to the PCM and the EM2 with shielded 22g and checked each one three times for continuity. I still get "nop" from the EM2 (i.e. no communication with EC2). There seems to be no spark or fuel while cranking which leads me to think that the EC2 is not triggering the coils or the injectors on either computer. There's 12v on both the EC2 power pins, and a good ground on the ground pin. The cold start / injector disable grounds the cold start pin correctly. The coil disable functions ground the pins correctly. I'm running out of things to check, other than check the same things again. I hate to say it, but I'm beginning to think that the EC2 is dead - but then it was checked as good by Tracy before he shipped it. I did hook it up when it arrived, and ran the engine briefly on the B computer. I've no reason to think this hookup to the old wiring fried the computer since my old computer checked out good when returned. Yet another check of the wiring tomorrow, then I'm totally stumped. Could I be missing something obvious? John (how do you spell frustrated?)
