Fuel Pump Whine?

megalapagas

This is a total different question but sort of relavent, I noticed on my fuel meter it just keeps 8 dots lit up meaning I have half a tank but recently my car sputtered and died because I needed fuel, how I can fix the problem so my vehicle can read how much gas I have??

Could be the fuel pump or a faulty indicator.

the Level indicator on the fuel pump assembly is easy to clean if its dirty (follow that fuel write-up on how to remove the entire assembly), but remember there's another sub-level indicator behind the drivers seat as well (see pic), same basic instructions for removal. Did you try a can of Seafoam just to get the funk out?

If this happened after just taking a very hard right turn, and if it took less than 19 gallons to fill the tank afterwords, than you have experienced the notorious 370z fuel starvation. This happens when a hard right turn sloshes all the fuel to the driver side of the tank (while the pump resides on the passenger side). There is a large hump in the middle of the tank that does not allow fuel on the drivers side to naturally make it to the passenger side where the pump can get it.

If the car was truely out of fuel and it took 18-19 gallons to fill it back up, than you have a bad level sensor.

There are 2 level sensors, one for each side of the tank. They are potentiometers that are wired in series. Think of your fuel level gauge as a voltmeter. Voltage is passing through both the sensors in a series, their resistance lowers the voltage changing the display on your fuel level gauge indicator.
