1998 Toyota 4Runner... First, few months ago.. my fuel light began going off and on even if my tank was full. Second, ocassionally truck would stall when at complete stop but would restart easily. Third, over last few weeks I began hearing an quiet ohmmm sound after starting and while driving. And now, truck just stalls at almost every stop. Now, it takes several turnovers til I can restart. This ohmmm sound seems to have something to do with what is going wrong/out..I think. A friend was riding with me yesterday and said its my fuel pump, however, the sound seems to be coming from the front not the rear/tank. Please help if you have any ideas.
