SOURCE: what does the red FL light mean on the display in

Some mechanic said it was a fuel injection problem, but almost always a loose connection.Prop up the tank and see if you can find something loose. Better you find it than to pay somebody to find it. Might just be a fuel injection problem, no pressure, gummed up, clogged, I wouldn't put any additives in your tank, not good, but if you do, only small amounts, burn high test. Then if all else fails, take it to the shop. Hope this helps.
