One day I was driving home, tuned into driveway(dirt) and car cut off.. I tried to jump it off but nothing.. The next day I jumped it off and it cranked but very slowly.. Since then I put a new battery and msd box in it.. I am not getting fire out of the distributor.. I know the inside has spark but nothing going to plug wires.. Anyone know what causes this? The car is still turning over but really slow on a full charge battery
