Crank no start, no spark

Howdy. Here is what i have 68 plymouth slant 6 six with points. Car has been sitting for about ten years. It ran when parked. It cranks but wont start. I really dont know what im doing, but here is what i have:
Battery: 12.6 volts
Key on points open: -coil 11.85 volts +coil 11.83 volts
Cranking with key: 10.39-10.6volts -coil.
Cranking with key: 9.11 volts +coil
-coil, key on, wire sparks when grounded
11.7 volts key on blue ballast wire
11.6 volts key on brn/blue ballast wire
8.2 volts cranking with key blue ballast wire
9.2 volts cranking with key brn/blue ballast wire
Ran wire from battery positive to +coil no start
Check voltage when points are closed same reading as when open « most of the time ». Filed points clean. Got a lower reading a few times.
