Sounds like the pump is failing, the carbon brushes on the armature in the pump wear down and loose contact after awhile which makes the pump stop working or the pump gets rusted or gummed up from crud in the tank. with the proper tools and knowledge it's not hard to replace a fuel pump but if you're not mechanically inclined you'd be better off taking it to a professional and using a decent fuel pump and always replace the fuel filter at the same time.

Fuel gauge is moving slowly to full


I'd use a couple of resistors representing full and empty. Take connector loose from fuel level sending unit at gas tank, two wires, use resistor between the proper two wires, turn key just to on, you shouldn't have to start it. If gage reacts properly to both resistors, I believe the problem is the sending unit in the gas tank. If it still doesn't function properly, have to check wiring circuits and instrument cluster. The resistor ohms, 16 ohm--and 158 ohms. These are just generic specs.
Some ford instrument clusters can do a self test. The only problem I have is, I don't which years this applies.
With the engine off, depress and hold the odometer reset button. Turn the key to the run position and hold until the gages sweep, within 5--8 seconds. Depress the reset button once to advance to each stage of the self test. Turn the ignition to the off position to exit self test. This test is w/o outside input, so if all gages sweep except the fuel gage, I suspect the instrument cluster has a problem. I'm not sure if your instrument cluster has the self test ability?

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.

Gas gage constantly says full when it's not!


Unfortunately this is most likely the fuel pump module, which includes the fuel level sensor also. This should be diagnosed more thoroughly with a scanner, a good scanner will be able to check instrument cluster separately to confirm the gage is working right,and check for trouble codes that may not light any warning lamps. Hope this helps. Rate me please.P.S. Dont use that fuel station any more.

Speedometer or fuel gage?

If speedometer which is bouncing around, it is likely a bad ground near where the speed sensor wire harness (which connects the speed sensor to the rest of the "network") exits the transmission housing. It's at the very back of the transmission (you have a 4T60E trans) to the left of where the right side half-shaft leaves the trans housing. Just look for damaged wires. If none, replace the speed sensor for $50-60.

If it is the fuel gage, the sensor is probably not "zeroed"--it's reading wrong, too high, and if it were to start at true "empty", it would read right. Thus, the gage is always reading a little high (maybe a 1/8-1/10th of a tank too high?). This isn't a problem until to stop, start, or turn quickly and cause the fule to slosh around in the tank and starve the in-tank pickup which sends fuel to the engine.

If it is the fuel gage, you should simply put as much fuel in as you can and see if the needle goes far above "F". If it does, note how far it went and then practice filling the tank when the needle is that same distance above "E".

Hope this helps.
