04 F150 TLRC alarm

greetings,

I am getting the audible alarm as soon as she warms up, I have the round digital tach but neither of the indicator bars on the bottom are lit or blinking. there is a check engine? icon on the the top right next to trim bars that is on but is not referenced in my manual, any ideas?

Check for water in fuel filter on engine and fuel/water separator filter in boat.

thanks for the reply, but I don't think i have that alarm on the filter on the engine, also its got fresh gas in a new tank, almost empty though.

I just replaced the H20 pump/housing as the engine has sat for a year, and was not pumping @ first try, its pumping now on muffs but seems a little warmer than it should be, maybe I will try running it in a garbage can today.
