... someone told me if the ballast resistor was bad it wouldn't start at all, is this true? ...
No, "someone" is wrong. With a broken ballast, the engine will start and run w/ key in "crank", but will die the second the key switches to "run". That is because the ballast is bypassed in "crank". Many posts. To verify, jumper from BATT+ to coil+, but don't run long that way or your coil will overheat.
