Sorry 'bout that, John.  Keep forgetting. 
 
 However, principal of checking the for continuity still applies.  Since I don't have an EM2 not certain that NOP "just" means no power.  It generally means "No Operation or Not operational" which it would be if no sensor signal input.  I understand that you believe the NOP means the Ec2 is getting no power - but, since you've checked that as far as you can and find power to the Ec2 box - try checking your sensor input or at least the continuity of the wires. 
 
Since you have checked the obvious,  you might try checking some less obvious things like whether your EC2 ground wires are truly are grounded.  No ground would probably appear as lack of power even though you checked the power leads - lack of ground would of course act as if you had no power to the Ec2.
 
Can't think of any other suggestions, so good luck

The two coils you will see inside the crank angle sensor distrubutor box  produce the "G" signal (that's the coil aligned with the top two spoke rotor - its on the right side of the case with a red dot on the small black coil
Ed, Mine's a third gen. It doesn't have a distributor box - just two sensors bolted to the engine next to the rotating trigger. I think the function and wiring arrangement is similar. It's a long time since I wired these sensors.
