Does fuel pump have anything to do with fuel gauge


The fuel gauge sender unit and the fuel pump are two separate items but on many cars they share the same space and are integrated into the same housing or unit.

It is unlikely each will interfere or affect the operation of the other unless the unit has been carelessly repaired and refitted. The fuel gauge float arm is particularly vulnerable to damage.

After much use the rheostat track the float arm operates becomes worn and might provide intermittent gauge readings but the most common reason for this is poor electrical connections.

Tip

Running gas on E


There’s actually a bit of a debate about this one. The old wisdom says if your car gets down to E, the sediment in your tank will get sucked into the system and foul your fuel injectors . Although some mechanics says thats not true. Either way, running down to E does pose other problems. You cut the life of the fuel pump considerably, since the fuel actually cools the pump.
An interesting note: Most cars can drive another 60 miles+ after they hit Empty, automakers call this extra gas the “buffer zone”. US cars have the largest “buffer zone” of any vehicles. German drivers, for instance, like to know exactly how much gas in is the car, so their “buffer zone” between the gauge’s E and the actual empty tank is much smaller.

2004 ford explorer fuel gauge fuse


If your fuel gauge isn't working , it's not a fuse ! The gauge or the sending unit in the fuel tank is bad . If you had other thing's not working in the instrument cluster I would say probably a fuse. There is not a fuse just for the fuel gauge .

Possible causes of 3,400 to 4,000 rpm engine cut-out


The speed buffer is bad. Older cars had these buffer modules out side the engine control module(ECM) Pre 90's. Newer cars have them built into the ECM. The buffer digitizes the analog signal sent from the speed sensor. This is the reason your car cuts out at 4000 rpm's. It's not recieving a signal from the speed sensor and thinks it's still in park.

Is there a fuse or relay for the fuel gauge,does the gauge share a fuse with other electrical consumers ?


should be a fuse in fuse panel for all gauges, not one per gauge.. there is a fuel pump relay on most fuel injection cars but that gives fuel pump power . most of the time if fuel gauge is not working its the sending unit inside the tank ,wich if your in there might as well change fuel pump to.

Fuel pump wiring diagram


there is two things : fuel gauge and dash fuel gauge. The fuel gauge in tank rated to 0 to 90ohms.disconnect wire at the tank take a variable resistor connect it to wire .read the dash gauge if it move as you move the resistor. if ok fuel tank gauge is at fault

How to replace fuel gauge on 1984 Grand Marquis


Are you sure its not the fuel sending unit and not the fuel gauge itself.Because the sending unit controls the fuel gauge level and if the float gets stuck then the fuel gauge will not work.

I have a 1999 ford expedition i have been have trouble starting it for a month now changed the fuel filter reset the fuel pump switch checked the fuses all good. It turns and half the time it starts now...


GO TO AUTO PARTS STORE BUY A FUEL PRESSURE GAUGE THAT CAN CHECK FUEL PRESSURE UP TO 100 PSI. LOCATE YOUR FUEL PRESSURE TEST PORT.LOOK FOR SCHRADER VALVE ON FUEL LINE NEXT TO EGR VALVE.PLACE A RAG NEAR THE SCHRADER VALVE AS YOU INSTALL FUEL PRESSURE GAUGE TO CATCH GAS SPILL AS YOU SCREW IN FUEL PRESSURE GAUGE HOSE FUEL PRESSURE 30 - 45 PSI WITH ENGINE RUNNING. THE ENGINE MUST BE OFF HOOK UP THE FUEL PRESSURE GAUGE.IF YOU HAVE TROUBLE THE FUEL PRESSURE GAUGE WILL HAVE INSTRUCTION HOW TO HOOK UP FUEL PRESURE GAUGE.BE CAREFUL CHECKING FUEL PRESSURE IS DANGEROUS JOB.DONT ALLOW NO MASSIVE FUEL SPRAYING WHEN HOOKING UP FUEL PRESSURE GAUGE YOU WILL GET CAR FIRE.

Trying to locate electrical junction to test fuel level sensor


Fuel Level Indication System The fuel level indication system is a magnetic gauge system. It consists of a magnetic fuel gauge (9280) mounted in the instrument cluster (10849) and a sending unit located in the fuel tank (9002) with an instrument cluster gauge amplifier (10E849) in series between the two. No instrument voltage regulator is used with this system. Fuel Gauge
The magnetic gauge movement consists of three primary coils, one of which is wound at a 90-degree angle to the other two. The coils form a magnetic field which varies in direction according to the variable resistance of the sender unit which is connected between two of them. A primary magnet, to which a shaft and pointer are attached, rotates to align to this primary field, resulting in pointer position. The bobbin/coil assembly is pressed into a metal housing which has two holes for dial mounting. There is no adjustment, calibration or maintenance required for these gauges. The instrument cluster amplifier is calibrated to the fuel gauge. The instrument cluster amplifier and fuel gauge must be replaced as a system. Instrument Cluster Gauge Amplifier/Check Gauge Module
The instrument cluster gauge amplifier electrically averages fuel sender readings so the fuel gauge displays actual fuel level and not fluctuations due to sloshing in fuel tank. The instrument cluster gauge amplifier is a small printed circuit board which latches into a pocket on the back of the instrument cluster. The electrical connections for ignition, ground, input from fuel sender and output to fuel gauge are made through a spring-type connector on the instrument cluster gauge amplifier to the instrument cluster printed circuit (10K843) on the instrument cluster. There are no provisions for calibration or adjustment of the instrument cluster gauge amplifier.
Fuel Sending Unit
The fuel sending unit consists of a variable screened resistor made up of a ceramic substrate. It is controlled by the action of an attached float in the fuel tank. When the fuel level is low, resistance in the sending unit is low. When the fuel level is high, the resistance in the sending unit is high. As the float moves from empty to full, the resistance will gradually and continuously increase. f9e3b50.gif

I recently changed my fuel tank sending unit in my 96 ford ranger but my gas gauge seems very sticky and will jump to the empty level periodically. I don't smell any gas leaking and I know I have gas in my...


the buffer plates in the tank seem to be loosely held! so sometimes they fall on the sender unit,causing the gauge to drop!!!!! when the vehicle is shaken!!!! remove that tank and have the plates checked!!!!
