/6 no start, has fuel. Walk me through trackdown process?

Ok I am no professional but I have been trying (unsuccessfully) to track down the same problem. So I am going to walk through the system layout and what you may expect at the various points.

Battery positive to starter
positive to voltage regulator
voltage regulator then goes 2 way
one to ballast resistor
one to alternator
with the key in the on position 8-9 volts at the positive and negative side of ignition coil
on the positive side of coil should be wire from ballast resistor and if you have it capacitor
from the negative side it goes inside the distributor
then from the tower to the distributor cap

Now the information I have found to test against.
The ignition coil should have 5-7 ohms across positive and negative terminals
and from the tower to the positive or negative should be 5k to 7k

i have seen several potential tests for spark from the tower
you can either get the spark plug wire from the tower to ground if you see spark then coil is good (This didn't work for me still don't know the problem)

If you have spark there you can then test the plugs same process take the spark plug wire off one of the plugs and plug a spark plug in and ground the threads you should see a spark across the gap.

I have seen suggestion that the rotor even if it looks good may be bad and require replacement. Also check the distributor cap for carbon buildup and the spark points.

If everything is good then your problem much like mine is beyond my skill. Admittedly my skill is limited. If anyone can suggest where to look for my problem I would appreciate it. I have checked the battery its good. I replaced the coil and checked it seems to be good and the voltages are correct.
