Cranks and wont start ongoing issue

Kit, I agree that it might be, its the one thing that is constant. When I check it to the battery it has 0 ohms, but cranking that can change. I have a ground strap at the back of the block to chassis and the battery to the front of the block. I need to talk with MSD, when I check the 3 wires to ground coming out of the dist the "orange" wire which does go to the (-) side of the coil, has 1.5 ohms to ground, the red wire is O.L and the black ground wire is O.L. Which tells me I shorted it out. With the 3 pin connector hooked to the coil and key on and the way it should be.

Battery voltage-(11.7 volts)
key on at coil (+)-(10.7 volts)
key on at coil (-)-(6.5 volts)
cranking at coil (+)-(9.0 volts)
cranking at coil (-)-(5.5 volts)

3 pin at dist disconnected everything else still hooked up

Battery voltage-(11.7 volts)
key on at coil (+)-(11.5 volts)
key on at coil (-)-(11.5 volts)
cranking at coil (+)-(9.5 volts)
cranking at coil (-)-(9.5 volts)
