Bought ski, previous owner put a amp and two speakers on it, tied into battery. It has a afmarket mpem where key doesn't have to be programmed. I would ride about 5 Feet and die. After three times all power is lost. Take out 5 amp fuse and stick back in fires right up. Now I am getting no spark.

Cleaned all connections to mpem, checked all fuses cleaned all connections in back box. Am getting no power to white wire that plugs into coil. Any help be appreciated !
