Distributor Circuit Problems

Okay, I just swapped in a JDM engine and the thing has been giving me difficulty left and right, it seems. The other day, it would crank, fire, and run, but misfiring all the while til it died. I changed out the plugs, made sure the timing was set right, realigned the distributor, and put it all together. Tried it again, this time it cranked, but no fire. I did an EFI diagnostic and it gave me Code 12:

'No 'NE' or 'G' signal to ECU within two seconds after engine has been cranked.'

It says to check the circuit, distributor itself, starter circuit, or ECU.

I did the checks on the igntion sections... everything I had failed though. Coil, pickup coils, and ECU resistance. I only was able to get a resistance value on the coil - .6 ohms, outside the norm. The pickup and the ECU, I got open circuit. I think that may be the problem, but why would it be working just the other day, it hadn't been moved or run since?

Suggestions?
