MSD Pro Billet ignition- are these unusually "voltage sensitive?" Got stranded, looking for ideas

If you don't have a battery meter, does the car crank over? If you have enough voltage to start the engine you have enough to run the ignition. I'd address the battery first.

Check for spark, if no then it's ignition. If yes, then you have a fuel issue.

This will be a narrow it down type of deal.

Who's clone ignition is it?
