Volkswagen people please make a suggestion!?

I have a 97 Jetta, 2.0, not getting spark from the coil. I do not have access to a VAG COM, but I have done a little testing myself. I checked the voltages at the coil plug connector, and its getting power and ground. The middle wire, signal from the computer, reads 2.8V KOEO. When cranking its supposed to vary in voltage, but I don't have the proper scan tool to check that out. I did a voltage drop from the computer to the plug on that wire, and its not losing any voltage. I already tried replacing the coil with a used one, no luck. I connected my universal OBD2 scan tool, and it is currently throwing no codes. I read somewhere that if you unplug the CMP it should throw a code when cranking, otherwise the pcm is bad, and I tried and it threw a code. Any suggestions?
