1965 Barn Find Dart starting issues

Does the distributor itself have a ground? Since I'm getting power to the distributor and not past, could it have a bad ground? Also is there any test to test the distributor other than pulling out a plug and checking for spark?

You're shooting in the dark and not following what others have suggested already.

The ignition is fairly simple, but after not running for so long there's probably multiple issues.

You'd do well to replace the spark plugs, wires, cap, rotor, and install an electronic ignition or replace the points. You're going to have to gap the points and even set the dwell to do it 'right'. Electronic ignition will be easier and improve your chances of success if you're not familiar with points operation.

You should also do diagnosis work: check voltage between battery negative and the following locations with the key in the ON position: battery positive, ballast resistor posts (both sides), coil positive. Then, disconnect your starter relay, have someone hold the key in the 'start' position and check the same exact things.

List all those voltages here and you'll probably get more useful help. If you don't do these things, you're relegated to throwing random parts at it and drawing the ire of several forum members who can't stand 'askholes' ;)
