Best Answer

Yes, a fuel pump can, sometimes, run without making enough fuel pressure to start the engine. It could also run long enough to start a vehicle but then cut out.

Additional answer

Sure it can. For example, a common sort of pump has a diaphragm in it and if this ruptures then the pump won't pump.

Can fuel pump be working and stop car from starting from car running out of gas?

you mean your fuel pump was working until you ran out of gas and now it doesn't work? yes, if you have an electric in-tank fuel pump, you need a new one. fuel pumps in the tank require lubrication to prevent them from overheating, and the fuel in your tank keeps the fuel pump "wet". when you run out of gas, you run it "dry" and will destroy the fuel pump.

If you run the gas tank low for a extended amount of time I have been told can "burn" up the fuel pump quicker than if you hold say half a tank or more at all times. A partially clogged fuel filter will for sure burn up a fuel pump.
