There's not that many wires involved. Positive/Negative from power supply. Positive and negative to the coil and then a plug in to the distributor. Double check that everything is correct. I'm not sure about the tach wiring (if you hooked it up, just unplug it) Check coil for both primary and secondary resistance. Make sure you have positive to positive/neg. to neg. It should run either way, but bad for the coil. Could be bad coil. Power might get to it but not through. Make sure rev limiter is plugged in or try another one. I'm not sure if it will run without one. If you are sure everything is hooked up right check the distrbutor pick-up. Call MSD and ask them how to test it with an Ohm meter to make sure its sending a signal back to the box. If its sending a signal to the box, then maybe you got a bad box. You said the box was good, how do you know??? I assumed that there was no spark coming from the coil. Stranger things have happened.
