Sump pump won't stop running

I am presuming you're asking about a basement sump pump, the kind that keeps your basement dry. Well, those things are not meant to run all the time. They are usually triggered by a float valve. That is a device that moves according to the water level in the sump (in other words, the hole). When the water gets high enough, the float activates a switch, the pump kicks in, the water is flushed away, the float falls and that turns the pump off until the cycle starts all over again. The frequency of the cycle depends on how fast the sump fills itself. I have one that kicks in five times a minute. Another might have a much longer off time. But don't be worrying about yours not being on all the time... that is how they are supposed to behave. Of course, if you have water flowing out the top of the sump, that is a sign things are not right with the pump. Then you really need help.

did it "conk" out or is the pump impeller stopped by a buildup of material ?? the reason I say this its very unusual for a aquarium pump to go completely out (ive had one running 24/7 for ten years) but in that ten years ive replaced two impellors and cleaned it out over one hundred times , and yes three months is the perfect time period for a cleaning needed !!!

A bad fuel pump may cause a 2001 Dodge Ram 1500 5.9l to run for a few minutes and just shut off without sputtering. It can also be that the fuel pressure regulator (on top of fuel pump assembly) is stopped up. Dodge Ram trucks have been named Motor Trend magazine's Truck of the Year three times.-----------------------------------------------------------------------------------------

it is possible that one of the three are going out on the computer, motherboard, harddrive, power supply, only a computer tech could tell which one.

Your problem may be one of the following:
First check or just replace the fuel filter. Usually located under the car in front of the rear axle, drivers side.
Next, the fuel pump may be worn out. Usually they get loud or stop working (running).
Next, check the fuel pressure regulator. Usually located on the front fuel rail, drivers side.
Is the vacuum line attached? Not leaking or rotted?
Also, do you smell a strong fuel odor when it won't start? May be one or more stuck-open injectors, or the coil pack is bad.
Checking these in the order listed will more than likely fix your problem.
The clicking noise indicates the battery can no longer run the starter, which also means the fuel pump won't run either.
It could be a fuel issue. How old is the fuel filter? Can you hear the pump run for a few seconds when you turn the key on? Try turning the key to ON without trying to start engine three times waiting for the pump to stop running each time. Then try to start the engine. If it starts, Its a form of Vapor lock caused by the extreme heat we have had lately, and a weak fuel pump.

If none of this works, try a new fuel filter first. From there have someone check the fuel pressure regulator and then the pump. If you are in need of a new pump, take my word for it and spend the money to get one from a Dealer, and not from your favorite parts store. Most parts store parts are made in China and they are JUNK.

Three things might do this. You did'nt say what year model or engine size to the answer is'nt your car specific. The car does run with the check engine light out? If it's running with the light on, you can stop at an auto parts store and they can check to see why the light is on. The coolant temperture senser can make the engine contol computer (think) that the engine is warmer than is is and not shoot enough fuel to keep the engine running good as it's cold . The engine takes less fuel to run hot and theirfore it runs OK. the fuel filter or the fuel pump could not be letting enough fuel pressure to get to the motor and again as the engine warmes up it needs less fuel and runs OK. Sometimes peaple put high octane fuel in an engine that does'nt need it and the high octane fuel burns slower and when the engine is cold it doesn't make as much opresure so it's harder to keep running but as it warme the presures of combustion are higher and the engine runs just fine. If the oil weren't change don the regular time and the oil is old the engine compression might be a lot less than it would be with good oil and the engine may have to warm to have good compression tp run well. If this is the case the oil may need to be changed a few times to get it clean enough to run well.

Check your float and the switch. It sound like it is just sticking. If it were bad the pump probally would not start

contacts are bad if you can fis it you will have to go to either a granger store or ele motor store to get them,, make sure they are in in the right direction or it might be easier to change the pump to a new one

sounds like your fuel pump is going out. One thought might be that the fuel filter is causing enough resistance to over heat the pump. I would check the fule pressure to determine a free flow of fuel.
