Hi, a hum sound in a motor that is plugged in means that it is either jammed mechanically or that The motor itself is shorted out and unable to create opposing forces to spin. You may try to remove any cover that protects the impeller (unplugged of course!) and see if there is an obstruction inside. If so, replace cover and retest. You should also note that these motors depend on water flow to be cooled. If they are operated for extended time without water inside the pump they will overheat and fail. Good luck!

Crosley washer won't agitate

Hello Carroll Mcknight - Is the washer making a humming noise? If so, either the drainage hose/pump is clogged and needs to be cleaned. If not, the unit may possibly be experiencing an issue with the door lock assembly, faulty pump, timer or control board not communicating correctly. Contact a professional to assist with the repairs and to move forward accurately.

What is the short hum i hear after trying to start the car and doesn't start

It's usually the fuel pump, which goes off once the fuel pressure is primed, but without hearing your vehicle, I can't confirm this.

Have to pump gas pedal and hold key to start, 30-50 seconds. when i get it started it and let off the gas it will sputter and sometimes stall. especially when in also seems to be overheating.

check the fuel pump, when you turn the key to the on position, the pump should start for a couple of seconds, it sounds to me like its not keeping the fuel line pressured any longer, which is why your having starting problems, when you turn the key to on, Listen for the pump to start, you will hear it hum ever so slightly,, after a couple of seconds it should stop, if it doesn't,, its losing the pressure needed, you can have them checked , its not very expensive to get them checked, having to pump the pedal,, doesn't help with this problem,, and the over heating is more than likely associated with it too,, if its not firing correctly, it will tend to over heat at times

Engine doesn't start. i heard a humming sound for a few second coming from fuel pump when ignition is on, replaced fuel filter but still not getting fuel delivery on the fuel rail. ASD and fuel pump...

The way you wrote your question, it sounds like you have already figured out that it is most likely the fuel pump. I would recommend you do a pressure test on the fuel pump to make sure.

NOTE: Some auto parts store will loan you the pressure gauges for free but you will have to either do it in their parking lot or leave a deposit to cover the cost of a new gauge.

When I turned my pump off to backwash and then turned it back on it made a humming noise then stopped running. Now it is doing nothing. what could the problem be?

sounds like a bad start capacitor, or there is something (rock, sand, or some debris) caught in the impeller.

The start capacitor not working will cause your motor to hum, then it will overheat and trip the high limit. It won't attempt to come back on until it has cooled. It's a common problem.

try clearing the impeller first, if that doesn't work and the motor shaft spins freely, then it's a capacitor.

Vehicle starts runs for 2 seconds then shuts off 2006 santa fe 4 cyl standard, not the battery started multiple times and shuts off after 2 seconds every time what is it?

Possibly a weak or dead fuel pump. Try disconnecting the fuel line where it enters the fuel rail ( the metal tube that the injectors are attached to.) Have someone turn the key to the "RUN" position, (not "START") a few times and observe the fuel flow. If it appears weak, then you probably have a bad pump. Be sure to capture the fuel that spills out and DO NOT attempt this while the engine is hot. Altenatetively, you can have someone turn the key "ON" and off a few times while you listen for the humming sound of the pump at the fuel tank. But just because you can hear a humming sound doesn't always mean the pump is operating to capacity. If this doesn't help, reply bvack and we can go from there. Good luck!

Turn on pump and it only has a humming sound. Motor does not start

Check your start capacitor. Probably best to remove the motor and take it to your pool supply place.
