Does it mean that your fuel pump is working if you hear the hum through the gas tank?

No, it means it is running. It may or may not be pumping gasoline with the proper pressure. Fuel pressure test will verify if it is working properly.

Why would a 91 grand am stall out after filling the tank and not restart even though the fuel pump is working?
how was it determened that the pump was working? just because you hear the pump working does not mean its working. it needs to be presure tested to find out if it has the right amount of presure. this is not uncommen for a fuel pump to be damged after running the tank low or out of gas,and even after a fill up.
Why do you not have fuel reaching fuel filter even though you can hear fuel pump when you turn key on?
Just because you hear the pump running does not mean it is actually pumping fuel. Run a fuel pressure test to see if the pump is defective.
What does it mean when the fuel relay and the fuel pump clicks?
that means both the relay and fuel pump are accuratelly working.
How do you check if fuel pump is working in vt commodore?
Open the fuel filler door and remove the gas cap. Listen at the fuel filler opening while a helper turns the ignition on but does not start the engine. The pump will run for a few seconds and then shut off. If you do not hear the pump check the fuel pump fuse and the fuel pump relay. If they are good then the pump is more than likely defective. If you hear the pump then you know it is running but that does not mean it is pumping fuel. A fuel pressure test will verify the condition of the pump. Be sure and replace the fuel filter.
If you don't hear the fuel pump buzz for a couple of seconds when the ignition is switched on does it mean the fuel relay is faulty?
Not necessarily... there are two fuses for the fuel system
How do you tell if the fuel pump is working on a Chrysler pt cruiser?
Have a helper turn on the ignition switch without starting the engine, while you listen at the fuel filler door with the door open cap off. The fuel pump will run for a few seconds and then shut down. If you hear nothing then the pump is bad or the fuse is blown or fuel pump relay is defective. Even if you hear the pump that does not mean it is actually pumping fuel. A fuel pressure test is the only way to know for sure if the pump is actually pumping fuel with the correct pressure. First thing to do is replace the fuel filter if the pump is running and the car will not start.
When Ford F-250 5.0 engine turns over no fuel is getting to engine all 3 fuel pumps are working?
Just because you hear the pumps hum does not mean they are working. Also, where is the third pump? There should only be two, one in each tank. I am not aware of an F250 with a high pressure frame rail pump, how old is the truck? Have you pulled the fuel filter and checked for restriction? What happens when you pull the line off and turn the key on? Does fuel come out? When you say no fuel is getting to the engine, do you mean you have no fuel pressure, or the injectors aren't spraying anything? Could it be that fuel is getting to the fuel rail but the injectors are not firing? Could it be that you are getting some fuel pressure, but not enough fuel pressure? What if your fuel guage is wrong, and you have two empty fuel tanks? These are questions you need to answer to eliminate things down to your cause.
Is there a way to check to see if a fuel pump is bad if fuel pump is in the tank?
You can have someone turn the ignition key to the on position without starting the engine while you listen at the fuel filler door with the cap off. You should hear the pump come on and run for a few seconds then shut off. If you hear nothing check the fuel pump fuse and fuel pump relay. If both are good the pump is defective. If you hear the pump run that does not necessarily mean it is actually pumping fuel. A fuel pressure test at the fuel rail well verify the condition of the pump.
Why would the speedometer in a 89 4Runner stop working after half a tank?
Do you mean the speedo, or the fuel guage?
Why a Mazda MPV doesn't work anymore after remove the fuel pump and clean it?
First off if you went to the trouble to remove the fuel pump you should have just replaced it with a new one. Hopefully you replaced the fuel filter. If not install a new one. You cannot clean a fuel filter. You need to make sure the fuel pump is actually working. Have someone open the fuel filler door and remove the fuel cap and listen at that location. Turn the ignition key on but do not start the vehicle. You should hear the pump run for a few seconds and then shut down. If you do not, check the fuse and fuel pump relay. If you do hear it run that does not necessarily mean it is actually pumping fuel. The only way to know for sure is to run a fuel pressure test at the fuel rail. You will need a fuel pressure gauge in order to verify this. If you do not hear the fuel pump run then either the fuse is blown, relay is defective, or the wiring to the pump is either loose, corroded, or disconnected. Any decent mechanic can solve this problem.
MEANIng of you could hear the wind whistling through the trees?
the wind is so strong that is bllowing through the trees
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.
