Gummy gas can definitely effect FI bikes. I've let my bike sit too long sometimes and it either won't start on the first try or run stupid sluggish. I've seen it trip the light when it does this.
To the OP, do you get any type of ignition at all and the bike just won't start? Will the bike just crank over normally and not spark at all or is t dead when you hit the starter?
That info would help others narrow it down for you too.
