Actually, the tach should be connected to the blue wire. That wire leads into the car and up to the cluster (also a blue wire) for the stock tach. All models are wired that way, even the DX's that didn't have a stock tach.

But that's beside the point. For now, disconnect the tach until you get the car running again.

Check for power on the small terminals of the coil, both should have battery voltage. The ICM could be blown. You can remove it from the distributor and have it tested, many parts stores have a tester.

Do not let the coil fire into an open circuit (cranking the engine with the cap off), that can blow the coil. You can hold a grounded test wire near the coil output to allow it to spark into a closed circuit. If only small yellow sparks are produced, almost always that means the coil is bad. If nothing at all happens, suspect the ICM more.
