Electrical issue (probable ground)

[Usudno]

Yesterday I dropped the roadster down for my first go cart. I have ran the motor probably 20 times since first start. Before dropping it down I zip tied any wires that might get in the way and torqued down the drive shaft. Once on the ground all it will do is crank. I pulled the plug wire off of the coil and I get one spark every 10-15 seconds of cranking!! No fire, or like I said very limited. Any ideas? I plan on going over my grounds again today. I'm running a blaster 2 coil and msd 6al
