if its fuel injected and u ran it on empty itll do that or ur floater is screwed up

your fuel sending unit needs replaced or the wiring is fried, probably at the pigtail at the tank. the gas tank has to come out. be sure to manually check the new unit before installing it so you don't have to pull the tank again. just plug it in, move the arm by hand while a buddy watches the gage move
