I called onstar and they ran a diagonistic and said service the fuel system is that like changing out fuel filter or is it more -
Answer 1
did they tell you the exact code?and yes there i'd say there is more to it than just changing fuel filter. they were probably just referring that it was a code flagging a fuel system malfunction. -
