no power to coil after motor swap

Just put car back to 91 specs, harness, computer, fuel injection ext.. just swapped to another computer harness thinking it was a problem. It didn't fix it, no ground signal from pcm or distributor to coil. It ran in another car........HELP ! I'm going nuts with this car
