No Spark

Hey, we have a 09 Teryx and has been sitting since December sometime. I though all was fine until my brother tells me it won't start. They get new plugs for it because he had gotten some bad gas in it and it still doesn't have any spark. I checked the coils they have power to the brown wires but not to the blue and green ones. I traced them out at the ecu and they aren't getting power there either. Our service manual says to check the ecu power supply which I did and both wires it said to check are getting 12 volts. Is the ECU bad and if it is should I just go ahead and upgrade or get a factory piece?
