Follow the fuel lines back to the VST on the bottom there is a philips screw and a black hose. Open the screw and fuel will come out of the hose, drain it into a clear container. Let it sit for a couple min. and tip to one side and look at the bottom for water.

I'm guessing there is no alarm going off.

Another thing to try is changing the spark plugs.
