You have 12 volts on both terminals because its is not being grounded by the ECU. The ECU may not be receiving a signal from the distributor module or the ECU has a problem, maybe grounding as mentioned, or is bad. If you disconnect the distributor 2 prong connector and tap the male connect on the harness side that goes to the ECU, that should trigger the ECU to fire the coil.

You are reading the "dead end" 12V on both terminals because there is no current flow. If no current flow through a resistor (coil) the voltage drop will be zero, thus the presence of 12V on each terminal.

That is 100% correct. To add if the ballast was bad you would not have voltage to the coil as it goes thru the ballast in the run position. And you said it read .9 ohms. Do the test where you touch the male end of the dist harness to ground and see if it sparks. If it dont you need the ECU and it it does its not seeing the dist signal. Ron

what he said and did you find out what ohm the ballast is supposed to be? did you make sure the ECU is grounded?
