No spark mystery on 7mgte

I've lost spark on my 88 7mgte and have hit a wall in my diagnostics. I've got 12v at the 3 coil pack connectors and the ignitor, the resistance on the cps connector pins is all good, but no spark. I tried a back up coil pack, no help. The one thing I can't figure out how to test is for the signals the ignitor sends to the coil packs to fire the plugs. Any ideas? TIA
