Step 1 is turning the engine over, so get that working before you worry about spark. 273 told you how to trouble-shoot that. However, from your later writings, I wonder if that is the problem. Maybe "not trying to turn over" means "engine turns over, but doesn't fire"?
Anyway, the coil body is not grounded, indeed the windings inside must be isolated from ground.
I also didn't follow the last sentence. Electrical problems don't usually change over a weekend. Good luck on Monday. If you need to get to work, have 2 alligator jumper wires ready (~18 awg). To power the ignition, run one from BATT+ to one side of the ballast, and the other side of the ballast to coil+, with no other wires on the ballast. You can even bypass the ballast, which will spark better until the coil gets too hot and starts missing (~5 min). Disconnect from BATT+ once you get to work or your battery will drain.
