Based on your opening statement "have twelve volts to hot wire on coil and five on other side" I disagree with the the bold text above. If it was sending the signal to the coil you would have spark. The Ignition Control Module (ICM) is on the negative side of the coil circuitry. The ICM momentarily completes the path to ground to fire the coil. Using a DVM set to Volts is not really the proper way to test that circuit.
