1988 Ciera 3.8L no spark

Hey, picked up an '88 Ciera 3.8L, former owner said it died while driving down the highway. I've since realized that he did some investigation and parts swapping. It has good fuel pressure but no spark. The CPS was removed, and never replaced. I picked up a new one and installed it. The ignition module had been replaced as well, and I removed it and had it tested anyway, and it tested bad, so I replaced it. I've also since picked up a used computer at the junkyard, of course that didn't help either. So, I'm looking for direction. The CPS has signal voltage, and ground, and seems to change as the engine is rotated. The injectors do pulse, and all fuses are good. Any ideas?
