fuel pump problems please help!!!!!!! ok so i just fount out that when you have a walbro fuel pump your not supossed to run the car when is low on gas, wich i did all the time for like 3 months!!!! well last time it hapenned the car started to run a little rought!!! my a/f gauge is not working properly and you can smell gas really strong from like 3 feet away!!!! my ses light came on 2!! and it reads my bank one o2 was bad and another one sayin somethion about the air to fuel mixture!!! what do you guys think fuel pump went bad??? or something else!! i prob. put 4000 mile on fuel pump!
Ususally when a pump goes out you just don't get fuel at all and the car simply won't start. I'd replace the 02 sensor and go from there. A bad sensor will cause the car to run crappy.
