Sammy I had a problem with my msd where my car would crank over fine but just wouldn't fire. I assumed it was flooded and put a charger on it and let it sit for an hour and came back and with the charger still connected it started right up. Happened a few times turned out the battery was bad even thou it read over 12 volts and cranked the engine easily just didn't have enough voltage to fire the msd. New battery problem gone.

Good luck Mike
