When you turn the ignition to ACC or On you'll hear a buzzing or whirring sound. If this sound isn't heard you'll have to drop the fuel tank and replace it. Get it done by a proffesional.
the fuel pump
Turn the key to the on position without starting the engine, listen closely or have a helper listen to the rear driver's side, where the fuel tank is. When the key is turned then fuel pump comes on, making a slight whirring sound. If there is no sound at all or something more than a slight whirring sound, it's probably about time to replace it. Also, if it takes a long time cranking to turn over the pump may not be building pressure properly.
Try checking to see if your fuel pump comes on. To do this all you have to do is remove your gas cap and it's easier if you have somebody there to help you with the next step. Get in the truck and turn the key to the on position not running, then see if the other person can hear a whirring sound in where you removed the gas cap. If you do not hear a whirring sound then it's time for a new fuel pump, and if it is you have problems elsewhere.
Your fuel sending unit is malfunctioning.
If the fuel pump is working it will presssurize itself. Any air in the system will dissipate through the fuel pressure regulator and the injectors. You should hear a whirring sound when the fuel pump comes on at engine startup. If you don't you don't have any fuel pressure. Check the relay and the fuse.
Probably the fuel filter is clogged and there was never anything wrong with the pump to begin with. Can you hear the pump making a whirring sound when you turn on the ignition. If so, the pump is all right and it is the fuel filter that is clogged up.
Normally only a very minor whir.
The yellow fuel dispenser is an indication that your fuel is running low. The red battery is an indication your charging system is malfunctioning. The red water symbol is an indication your cooling system is malfunctioning.
If it is malfunctioning it can affect fuel mileage.
If the old one is malfunctioning, yes.
The fuel pump is located within the gas tank. It is the gas that keeps the fuel pump cool. This is why you should not run your fuel tank empty, or the fuel pump will burn up and will have to be replaced. The correct method to test to see if it is your fuel pump that is malfunctioning is to leave the car door open and simply place your key in the ignition and turn it on. You should hear a high pitched whirring sound from under the rear of your car. That is your fuel pump turning on and powering up. No sound and it may be dead. The correct method to replace it is to drop the fuel tank and then it inserts from the top. Most, however, lift out the back seat and cut through the sheet metal under the rear passenger's seat to expose the fuel pump location and change it out in this fashion. Then they bend the metal back down and seal it up to make it water proof and to keep out any fumes. Instructions for replacing the fuel pump are on the web if you search for them.
first have an assistant turn the ignition switch to the on position and listen for the whirring sound from fump pump, indicating pump is operating. If fuel pressure is in question you can install a tee fitting between fuel filter and fuel line and purchase a fuel pressure gauge to connect to the tee fitting. fuel pressure should be at 43psi with key on engine off, and 34 to 36psi with engine idling.
What you are hearing is probably the compressor for the load-levelling shocks in the rear of the car. That sound is normal.
what vowel sound do fuel has
Could be either. Start with replacing the filter then if it still has trouble do a fuel pump pressure and leak down test.
It depends if the starter is turning the engine over and its not starting the problem is not with the starter its with your ignition or fuel system most likely, If your start is making a whirring sound then its not making contact with the flywheel and you probably need a new starter
If the ticking sounds like a "normal" ticking, it is probably the fuel injectors.
The 1997 Ford Explorer fuel gauge can be stuck on fault because the fuel float is malfunctioning in the fuel tank. The fuel gauge fuse might be blown.
A 1990 Jeep Cherokee malfunctioning fuel gauge can be caused by a broken ground wire. The gauge will not function if the fuel float in the fuel tank is broken.
Check that the fuel pump fuse is good. Make sure there is enough fuel in the tank. The fuel pump roll over switch may need to be reset. The fuel lines may need to be purge of air. Fuel pump may have to be replaced. If you turn ignition key on first before starting listen for a whirring sound that usually indicates the fuel pump is operating. If so check the other tasks first. Good Luck.
Probably the fuel pressure sensor malfunctioning...
A malfunctioning EGR valve can definitely lower fuel economy.
I am not familiar with a vg30 but if it has a carburetor the float fill valve is bad, and if it is fuel injected the fuel pressure regulator, or the injector circuit is malfunctioning.
Usually the fuel level sensor in the fuel pump. ANSWER A 1993 Ford Explorer also has a 15 amp fuse in location # 17 for the fuel gauge
