'00 G/Am fuel problem, will start unless gas is over 3/4.

Need help! I have problems with the g/a. it wouldn't start and we thought it was the fuel pump, but the pump is still buzzing when the ignition is turn to on. So then we replaced the fuel filter. And it still wouldn't start. We had added more gas, which was already between 1/2 and 3/4. We filled it to 3/4. Will it finally started. The thing is the car well only start if the gas is over 3/4. If runs below maybe about 1 gal. below 3/4 and the car is parked overnight. It won't start the next morning. unless we add more fuel. making sure it's pass 3/4. Would anyone have any suggestion on what may be cause this.

Probably your fuel level sender inside the tank is not working properly or the gauge itself is not working right.

I would go ahead and go to a gas station and fill it up until the pump stops pumping when it detects that the gas tank is full. Check how much gallon of gas was pumped into the gas tank when it became full. Check your vehicle manual what capacity the gas tank holds.

Reset your Trip Odometer. Check your manual how MPG you get while driving in the city and MPG on the Highway. You should be be able to gauge when fuel is half empty and the fuel gauge should display 1/2 as well.

There was a report on the news during this summer that some of the Gas stations and I think Shell was one of them in which their gas contained the natural chemical which was suppose to be removed during refining but was not. It had caused many vehicles that used those fuel with that chemical still in it and caused fuel senders in the gas tank to become corroded and thereby provide innacurate reading. The drivers has to use their Odometer to gauge when 1/4 level by looking at their Odometer and then fill up the gas to full. When the fuel sender is corroded, then it must be replaced and possibly the fuel pump as well while at it.
