Question about 2005 Ford Taurus

Open Question

Fuel Comp Error Ford Taurus

I have replaced the fuel sending unit in the gas tank. Looking at the gas gauge, it seems to try and read fuel if you disconnect the battery cable and reconnect. Could it be the Power Control Module or the Anti-Slosh Module?

    There is a fuel module in the circuit between the sender and the gauge..It should be under the dash on the driver side..I havent heard a anti-slosh module,,but thats more then likely the same one im talking about..If you find it lightly tap on it and see if it makes a difference..

SOURCE: 1966 Ford Mustang Gas Guage not working

I had a similar problem. In my 1966 Mustang gas tank, the fuel pick-up was on a "float." My float developed a hole, filled with gasoline, and sank to the bottom of the tank, therefore, the gauge always read empty, but the car ran well. All the other gauges of course worked correctly. The repair was a relatively simple soldering job (after removing the float from the tank), but if that is indeed the problem, ensure all the gasoline is drained from the float before beginning the soldering job.

From what I understand even a "qualified" Ford mechanic has problems locating this and if you look at a pre-2000 Haynes or Chilton manual it shows it being in a completely different location but to answer your question from what I understand (never changed one myself) it's on the passenger side, under the dash and should be by the radio. Should be held on by one or two screws. Also easy to get to if the radio is removed.

SOURCE: Help replacing fuel pump and sending unit 79 Ford Fairmont

you should have two metal bands/strapes hold the tank in place, a bolt on each end of the strapes. disconnect the fill neck, supply and return lines, the wires for the pump and sending unit. if possible get the fuel level as low as you can. gas is heavy. lift the car up as far as you can, i say 2 and a half to 3 feet off the ground. a car lift is even better. the fuel pump will be held in place with a ring, use a hammer and punch to drive the ring counterclockwise to remove. don't let any dirt go into the tank.

I changed fuel pump. Now the gas gauge does not work


year/make/model?? Does the gas gauge read empty or hard full? If it reads hard full, suspect a ground problem at tank. If gauge doesn't work at all, make sure there is power to the plug at the tank. It is also possible the float arm may have become disconnected as some of these units are tight to get back in the tank. I have also seen new pump/gauge assemblies with defective sending units resulting in non working fuel gauges.

1999 PLY GRND VOYAGER GAS GAUGE WOULD NOT READ GAS AFTER HALF TANK, JUST REPLACE THE WHOLE FUEL PUMP AND STILL NOT FIX


You forgot to mention the FLOATER in your tank,To do this, you have to drop the tank but be extra careful you're working with gasoline.De-pressurised it first before you start. Oh yes, disconnect battery.!!

Gas guage doesnt work


It sounds like a problem with the fuel gauge sender unit in the fuel tank which has worn out and gone open circuit and needs replacing. Access to the unit is usually through a removable plate in the floor in the rear of the vehicle. Disconnect the wiring connector and any hoses and then remove the securing screws. Replacement is done by reversing procedure.

Gas guage not working


Voltage from the battery goes through the ignition switch, through a device in the instrument cluster called a voltage regulator (though it is really misnamed), through the gauge, through the wiring to the gas tank, through the sending unit in the gas tank to ground.

The sending unit is an electrical wiper that slides across a peice of resistance wire. the movement of the float moves the wiper. If the sending unit no longer makes electrical continuity, the gauge will read zero. If the sending unit wiper is shorted out, the gauge will read full.

Try grounding the wire at the tank to see if the gauge maxes out, then disconnect it to see if the gauge zeros out. If all that happens, your problem is the sending unit in the tank. If none of that happens, your problem lies closer to the front of the car. While you are under there, you should measure the resistance from the terminal on the tank to ground, just to verify that the sending unit makes some electrical contact.

If the other gauges work OK (temp, oil pressure) then the "voltage regulator" is probably working fine, and the problem is the gauge itself.

If you have no other gauges (excluding speedometer, tachometer and battery voltage meter -- they work differently), then try this:

Put a voltmeter on the part of the fuel level gauge that is supplied by the "voltage regulator." The voltage there should regularly cycle between near zero to 10 or 12, back to near zero, etc. If you get that cycling, then it is most likely the gauge.

My 2008 chevy malibu fuel gauge dose not read only some times when its a full tank the gauge is dead but about 1/4 tank it reads but gos in and out ?


this is caused by a defective gas gage sending unit, the sending unit is part of the fuel pump module inside the gas tank, the gas tank must be removed to replace the fuel pump module that also contains the sending unit.

The gas cage is not working//


Inside the gas tank is the fuel sending unit. It is a floating device that is held on rails and it slides up and down depending on gas level and then sends a signal to the gas gauge. Either the float is leaky or it is stuck. The down side is you have to pull out the tank, then use brass punch and knock the ring counter-clockwise until it becomes loose. Then pull out and change the sending unit. Do make sure negative battery cable is disconnected and wiring harness and fuel lines are disconnected before pulling the tank.

Gas gauge has spun past full and appears stuck behind empty peg.


the fuel sending unit in the tank is a rheostat wrapped wire it increases the resistance read at the gauge the more fuel the more resistance.
what it sounds like is a dead short either in the sending unit or the wire running to it.
to check sending unit in the tank, locate the closest wiring harness plug (in the trunk/or under car) and disconnect then check gauge reading,remember ignition must be on.
try that and get back to me if needed

2000 Buick Century gas gauge reads full all the time


You're either looking at a short in the wire that goes to the fuel sender, or a bad fuel sender. If it was just a broken wire, it would read empty instead. The fuel sender is a permanent part of the fuel pump, so that has to be replaced as a unit.

Gas gauge reading empty even when tank is full


Usually if the gas gage does not work yes it is true it may be the sensor if it is electronicly controlled. the sncor will more than likley be in the tank. here is how to remove your gas tank.

  1. Before servicing the vehicle, refer to the precautions section.
  2. Relieve fuel system pressure.
  3. Drain the fuel tank.
  4. Remove or disconnect the following:
    • Negative battery cable
    • Fuel filler and vent hoses
    • Fuel tank skid plate
    • Fuel tank wiring connectors
    • Fuel supply and return lines
    • Fuel tank
    • Fuel pump assembly

I have a 94 chevy s10 and my gas reads empty while i drive.but when i shut off the truck the gauge moves to different readings.


Is......the problem--"the gas gage reads empty when there is fuel in the tank. OR, The gage moves when the key to turned off ?

If it's the first,
You will need to test the gage and through process of elimination, determin if the Sending unit inside the fuel tank has gone Bad.

If its the second ? - Electrical gauges will move when powered down. Normal

Testing the gauge may not be easy - just depends on your ability.
It is a simple 2-wire gauge circuit, when disconnect (usually need the fuel tank) the gage reads in one direction (either full or empty)
then when shorted-the gage reads in oppisite direction.

Of course you must select the correct wires or you may short out the wrong circuits!! Most GM vehicles use a purple wire & black wire.

A quick method I have used to check the in-take part of the gauge is this.
1st. know there is gas - 1/2 tank works best.
2nd driver's door open, key in run position, engine not running.
3rd gently lift up on the door then let if come back down, gently.
just enough to cause the gas to slosh around.
4th - keep an eye on the gas gage, a bad sending unit in the take will show up as a "twitchy" needle.

Of course, if the gage never leaves empty - sloshing won't work.
I have a known good sending unit I can plug into the vehicle and simulate different levels of fuel - if the gas gage works, I know the problem is in the tank.

Let us know.
