I just started my engine up this weekend for the first time to break in the cam....ran for 15min and died.....no fire after that! spent a better part of an hour going every darn connection i could think of....came down to the cannon plug....if you pull it apart you will find the pins are actually split in half....mine looked like they were smashed together so there was no spring in them to make contact with the sides of the mating connector.....took my knife and spread them open and voila!
