"no matter how long the compressor runs" If it's not connected to any high volume consuming devices, and that no leak has been detected...then either an head valve (checkvalve) , severed motor shaft, nor the piston/diaphragm is defective. If it does stop after a few minutes the gauge is surely defective

How do I check the fuel lines before I go replacing the fuel pump? What other things should I check? It's a '02 Dodge Dakota sport v6 and it wont start the battery&starter are good it cranks and

If you want to replace your fuel lines and check the pressure the first thing you're going to have to do is get a fuel line pressure gauge that's the only way that you can check to make sure that you are getting adequate fuel to your engine is with the gauge now do you have the specifications on how much pounds per square inch of fuel is delivered from your pump to your engine some cars at 60 PSI some cards at 70 PSI it's all about whatever you have but that's what you need

I have a very high all purse I also have a manual gauge.I replaced the gauge this morning oil pressure stayed the same when its cold it will run over a hundred never did that before it usually...

It would help to know the year, make, model of the vehicle, as well as engine type/size. But in general, that would indicate a faulty pressure relief valve, which is usually located as part of the oil pump, which is inside the engine's oil pan. A cheap first step is to also change the oil filter and oil, as a clogged oil filter would not help matters.

DeVilbiss air compressor will not build pressure

Does it have an intake air filter? Has the compressor been properly maintained? Oil less? It may have worn out rings and or valves

My friend has a Mercedes benz C200D it cranks but is not starting

If system voltage is too low the computer won't send any current to the solenoid. So the lights stay bright instead of suddenly getting dim and you getting that click-click-click sound. And now that you have added details that sounds even more likely that the battery is done.Engine cranks normally, but it does not fire: You turn the key to start and hear the starter motor crank the engine, but when you release the key, the cranking stops and there is silence. This means that the battery and starting motor are working properly, but the engine is not firing. If you continue cranking the engine over in this way, the battery will eventually run down and will need to be recharged, but the battery and starter are not the cause of your problem.There are a number of causes for this type of no-start condition, the most common being that you are simply out of gas. Assuming that you have fuel in the tank, you will need to go through a series of tests to determine what is causing the problem. The testing procedure requires that you use specialized equipment in order to determine the problem area. There are three main tests in order to get you pointed in the right direction. You will need to test for Spark, Fuel and Compression, in that order. As soon as you see a problem in one of those areas, that is where you will need to concentrate your efforts.Spark:An easy way to test for spark is with an inexpensive spark tester. This is a device that is readily available at most auto supply stores. You use it by simply holding it next to a spark plug wire. If you see the neon lamp flashing while someone cranks the engine, then you have spark and should move on to checking for fuel. If there is no spark, or a very weak spark, you will have to do a series of methodical tests that vary depending on the type of vehicle. You will need a repair manual for your car in order to get the correct diagnostic procedures. A good source for on-line repair information at a reasonable price is Alldata-DIY.Fuel:First step here is to listen for the fuel pump running inside the gas tank. When you turn the key to run, you should easily hear the pump come on, run for a few seconds to build fuel pressure, then turn off. If you do not hear it, it could mean that the fuel pump or circuitry is bad. (Fuel pump failure is a common problem on modern cars.) Fuel injected cars are very sensitive to proper fuel pressure. If the pressure is off, even by a few pounds, it will cause noticeable performance problems, or a no-start condition. To check for proper fuel pressure, you will need a fuel pressure gauge that is suitable for your type of system. A fuel injected engine (found on just about every vehicle less than 20 years old) produces very high fuel pressures and requires a fuel pressure gauge that reads up to 100 pounds per square inch. This type of gauge has a threaded connector that must match the pressure tap on your fuel rail. Since you are working with a highly combustible fluid which can be quite dangerous if you do not know what you are doing, you should leave this step to a pro.

Grundfos pump switches on & off continuously with

if you have a pump for the whole house you need to check the bladder tank. there is a air valve on the top. Check the pressure with a tire gauge you should have at least 20 PSI this will stop the pump from the on and off thing.

You can compress air yuo can not compress water. thats why the ballder tank. As the pump work to shut off pressure it is compressing air. then when you use a little water the pump does not run until a large about is run then the pump will re fill the system

Best of luck

F350 super duty 2004 ford won't start, is firing but won't start at all. Changed fuel filter and pressed the reset button on the fuel tank and still won't start.

just to be sure.....attach a fuel pressure gauge to your fuel rail ....just to see if you have fuel pressure......if theres not enough pressure it won;t start at all.....even ten pounds shy.these gauges can be bought at your local auto store

Water pump cycles to often. When pump turns on, pressure gauge shoots up to 50 lbs right away without pumping much water.

Sounds like a well fed system with a pressure tank that has lost its air charge. Check for a water tank with a tire pressure type stem fitting, should also have a pressure gauge. Most newer tanks have a rubber diaphram inside to keep the air and water from mixing, but a lot of older ones don't and the newer ones will develope a leak that will produce the simpoms you describe. Try adding a few pounds of air pressure to the top of the tank and check for leaks. Warning: Compressed air can escape explosivly if the tank is badly rusted out but if your water pressure goes to 50# without the tank leaking, it should be safe to add up to 25# of air. The air charges the water system and allows the pump to shut off until enough water is used to lower the pressure back to set points on the control switch. It's not a good idea to adjust the set points on the switch unless all parts in the system have been checked for safety to the new pressures.

Craftsman compresser md 919155730

This sounds like a pressure switch failure. follow the power cord to where it enters the compressor and the switch should be there. you should be able to order a new one through sears service center. Good luck.

1998 Pontiac Sunfire won't accelerate

I assume that you do not have a "check engine" light?

The next thing I would do is check the pressure from the fuel pump. You can have this done at your preferred garage, or by purchasing a fuel pressure gauge from any parts store.

Vent the fuel tank vapors by loosening the fuel cap. Remove the electric fuel pump fuse and start the engine. Allow the engine to run until it runs out of fuel and stalls. After spinning the engine over for a period of 3 to 5 seconds, turn off the ignition switch and install the electric fuel pump fuse. Next, install a fuel pressure gauge in the fuel rail supply line, and secure the fuel tank cap. With the ignition key in the on position, verify that no leaks are present and start the engine. Visually verify the PSI reading on the gauge. The pressure for your vehicle should be 41-47 PSI (Pounds per Square Inch). Hope this helps and good luck!
