Fuel pump cycles while engine off?
New to the forum, just got 88' GTA and am having trouble with fuel pump coming on when engine is off sometimes. Will cycle for a few seconds and that's it. Have replaced fuel filter and fuel pump relay and just disconnected oil pressure sensor and oil sending unit...still doing it. Also when this occurs car takes a while to start and can smell gas odor. Problem comes and goes, any help would be greatly appreciated.
