Ignition coil secondary resistance is high / hard start when hot

I had posted in another thread a problem re: car starts when I let go of key when hot. I found that there is fuel and 7 volts at the ballast resistor when cranking and it jumps to 11 volts when I let go of the key. It doesn't seem like the engine is firing at all. Once it does start after letting go of the key it runs fine although I really haven't put my foot in it as its new and I am still doing maiden voyages. I just checked the newish coil resistances (AC Delco E552C) and see that the secondary resistance is 14k ohms. I can't find published specs but seems high. Perhaps its a dud? I have a spare old Delco Remy coil that is 1.7 / 10k ohms which I will try.
