fuel pump in tank

[eyeletboy]

checked the fuel pump in my tank and found out that it's working ???any suggestions why my car runs out of petrol when it's showing a quarter of a tank on the needle?

is the fuel level sender unit sticking have you tested it?

[eyeletboy]

where is it?and how do you test it? :-[

[carrie]

in the tank its a float on an arm connected to a variable resistor if it is sticking/faulty it could be the problem.

[eyeletboy]

ah,right i'm with you

[carrie]

probably you have checked this but does the needle on the fuel gauge go back to zero when the ignition is off. ie the needle isnt sticking is it.

check your pump in the tank again, but this time using a cocktail stick move the propellers around inside using that small opening on the bottom of the pump, the pump maybe working but the propeller may been knackered mine fell off, so it will buzz away but not actually do anything. and have a look in the bottom for any crap in the tank, that screws up your pump and makes it work on off on off. just an idea cured mine

if the gauge is reading fuel and it runs out of petrol personally i would check the gauge first as if there is no petrol the pump has nothing to pick up anyway.

cheers guys n girls.will have a look first thing again in the morning.the only good thing about this so far is that i'm giving the back seats a good cleaning cause i had to take it out

sorry carrie,yes the fuel gauge is going back to zero when the ignition is off.the last time the car done this i checked if there was petrol in her and there was so that lead me to the fuel pumps.
