Used ski yesterday and all was fine but came back due to low fuel. Put on skiport, filled tank and does not want to run, sometimes tries to start. CHK-ENG light does come on and when I checked it out found it to be code-P0231 which could be faulty wiring. Just seems odd that it worked fine for two hours on the water just before I put it on port?? Any help would be appreciated as have not started checking out all of the wiring to the fuel pump as yet.
