Fuel gauges in general are a separate from fuel pump circuits. Usually you start by finding the fuse panel and check the gauge fuse, if the rest of your gauges are working this usually means the fuse for all gauges including temp, oil, fuel are ok. Next you'll have to locate the sending unit wires at the fuel tank and look to see if any are disconnected or damaged and have good clean connections. Next consult a factory manual regarding the method of checking the gauge some companies ground the wire or while others manufacturers require a variable poteniometer usually between 0-100 ohms resistance. slowly turn the pot from 0 through the specs to cause the gauge to sweep from empty to full while watching the gauge making sure it sweeps smoothly. If the gauge is fine the tank will have to come down and a new sender installed, also while you in the tank check that the fuel gauge float does just that floats!

Still wondering if a new fuel filter comes with new fuel pump?


Most cars have a strainer before the pump inlet and a inline external fuel filter. some have the filter and pump as one unit installed in the tank. the fuel gauge and float are attached to this unit . it is possible that the pump relay may be on the way out.

Sorry, if this is a silly question, but is a new Fuel Filter installed automatically/come with a new Fuel Pump? Or do you have to buy a new Fuel Filter and attach to the new Fuel Pump before installin


Has the filter ever been changed? Need to know year and model of the truck. Fuel filters can be near the tank or under the hood. Filters are usually separate from the fuel pump.

I got a 92 blazer/Tahoe I have a brand new fuel pump kicks on strong but no gas is being brought from the tank to the engine I took the fuel filter off to see if its clogged I primed it and no gas comes...


Are you sure the wiring harness for the tank is plugged in ?
The pump and the gas gauge are on different circuits, but they both use the same ground.

I changed the fuel pump in my 2002 kia rio but the gas gage still dont work


Gas gauge has nothing to do with fuel pump. possible causes:

1. Low fuel in tank, get some more fuel
2. Rat chewed the fuel gauge wire or its socket is loose
3. gauge itself is faulty

Wondering if theres a fuse for the gas gauge in the econoline 150, or what could make the gas gauge only work part of the time


Hi!

There is a fuse for the GAUGES, but if it was blown, nothing will work. If your Gas Gauge is acting erraticaly, the problem is most likely the Fuel Level Sending Unit, part of the Fuel Pump, unless you want to remove and replace the fuel pump, your problem will be there til then.

Note, the failure of the Sending Unit does not mean there is something wrong with the fuel pump.

Good Luck!! Don't forget to rate this post!!

If my 1997 Plymouth Neon needed a fuel filter or a fuel pump what kind of problems would my car have? The gas gauage only works half the time and when it doesnt work my car doesnt run, when put into gear...


Your symptoms sound like a fuel pump, not the filter. The gas gauge is controlled by a sending unit that is mounted on the pump in the tank. If the gauge is sometimes not working, chances are, neither is the pump, which would cause the car not to start. The pump not only provides fuel, but also pressurizes the fuel system for the injectors and throttle body. The fuel filter would cause poor mileage and hesitation when accelerating. A completely blocked filter would cause the car not to run, but your gas gauge would still work since it's reading the level of fuel in the tank, not whether it's coming through the line to the engine.

Replace fuel pump-stil no start


Was it empty when you parked it? (i.e. did someone drain the tank, and put sugar in it? something like that?) If not... the fuel filter could be clogged. Check that. Most cars of this age are fuel injected, so the fuel at the fuel filter will be under high pressure. Chiltons manuals usually discuss how to de-pressurize the line if needed. But you probably already dealt with this changing the fuel pump. Good to hear it's turning over. After (finding) the filter... check to see if any fuel is making it through the filter. Turn the ignition to "on" and it will likely start the fuel pump and spray fuel everywhere (if you disconnect the filter output.).... besides having a mess, you will know your fuel pump works. (Try attaching a hose from the fuel filter output to a bucket to prevent a mess and possible fire please ). Can you hear the fuel pump running? Could be a blown fuse for the fuel pump.
