What should coil and ballast resistor voltage be?

Perhaps this coil voltage issue is a red herring. If I go back to the beginning the car was hard to start when hot. I mentioned it (albeit in another post) that it seemed like it started when I let go of the key. Perhaps it did this reliably when cold but not when hot. I dunno. I dug out my spark tester and see that even when fairly cold there is no spark when cranking but spark when I let go of the key as the engine fires. :BangHead: I'll have to think about where to go from here. I don't have a spare ECU. I do have a ground wire from the ECU to the firewall.
