I turned off my truck one day and heard a noise so i checked it out.
it was coming from the area around my gas tank and fuel injector atop the engine.
sounds like the fuel pump is running and air is blowing into the carburator...i had to disconnect the battery to get it to stop. i reconnected the carburator and it started again. whats the dealio?

The fuel pump is suspect but I believe there's also a fuel filter inline on the underside of the drivers side chassis. Fuel works off pressure so if the filter is clogged, the pressure remains between the fuel tank and the filter. Once the fuel has siphoned off between the filter and injectors, it dies but because there's positive pressure at the fuel pump, it won't come on until the pressure slowly seeps past the clog after hours. It's worth a look!
I have not, but I would guess it depends on what type of sender unit they use to let you know the level of gas in the tank. I would think the noise is more pronounced when the tank is closer to empty than full. Usually, the sender unit is part of the fuel pump, so you're looking at a few hundred bucks to get a new one. Turn up the radio :-)
First check fuse in fuse box that powers fuel pump. If this is ok then turn key but do not start just till gage lights come on and listen for humming noise in gas tank, it will only run a few seconds so you might have to do this several times to hear it. Is best to have someone listen around gas tank area while you turn key..If you do not hear humming noise then this would indicate that pump is not working and needs to be replaced.....good luck and if this info is a help then Please rate my post...
First make sure you have lots of gas in the tank, between a quarter and half. Turn the ignition on and listen for a humming or buzzing noise coming from the tank. The fuel pump should run for a few seconds. If there is no noise you will have to check for a blown fuse. No bad fuses, change the fuel pump.
If the pump runs, remove the fuel line from the tank end of the filter and turn the key on for a secoond or 2. If there is lots of fuel then replace the filter. If fuel just dribbles replace the pump.
If you have to work on the fuel pump, make sure the electrical connections are not corroded and are not loose. Also check the rubber hoses at the connection. Sometimes they will go soft and collapse, plugging the fuel line. Make sure you put the fuel lines back on properly. Hope this helps.
first you need to find out if the fuel pump is kicking on or not by turning the key forward (without starting the car) and listening for a humming noise coming from the gastank (your new fuel pump) if no noise is heard, you need to check your connections.
Could be the electric fuel pump if so equipped. What area(s) of the car the the fuse control, that should give you a hint. Some cars have a fuel pump system that the pump kicks on and off to keep proper fuel pressure up in the fuel lines. If not working right will run battery down in a few days.
Check the following: Turn the key to the on position (so the dash lights go on, but the engine does not crank) and listen for a 'whirring, or humming' noise coming from the gas tank. This would indicate the fuel pump is working. You should hear this for about 5 seconds. No sound, you may have a bad fuel pump. The gas in the tank keeps the pump cool, if it overeats it can fail. Change the fuel filter. It is possible you just drew in sediment from the bottom of the tank, and it is plugged up. If this doesn't fix it, let me know so I can help further.
