SEADOO RXT 260 (2011) does not start

[Eguchi]

I'm having problems with my SEADOO RXT 260 (2011) the panel turns on normally, but doesn't make any beeps... the engine turns, but doesn't start, I've already damaged all the fuses, the spark plugs are sparking... the fuel injection... This happened after spending the winter without turning it on...the battery is new, I think it's an electrical problem: any suggestions?
