sorry just reread the posts and you had already answered my questions:

Did some more checking.
checked + side of coil with key in run got 12 volts
checked + side of coil when cranking got 7.5volts
checked battery post on starter "large lug" when cranking drops to 7.5volts
check battery- to inside trunk cable disconnect 12.25 volts = checks battery to ground on frame is ok problem before

That is a lot of voltage drop though.

Found this in a another forum:

"I am a far cry from being an auto-electric expert. I can tell you the service procedure for testing the pick-up coil in the distributor. Connect an ohmmeter to the pigtail leads of the distributor, resistance reading should be 150-900 ohms. Another test is to connect one lead from the ohmmeter to ground and the other to either of the pigtail leads. If the meter shows a reading the pick-up coil is bad. I got this information from my blue Motor's manual. In my experience Motor has always been the gold standard of repair manuals."

I always lean back to... It worked... I did something... now it doesn't work. bo back to what I did and start from there.


Simple test.... pour some fuel into the carb. leave fuel pump off, see if it starts. if it does then the added drain on the battery of the fuel pump might be reason for no spark / start
