The fuel pump went ou on my truck so we replaced it! Now the gas gage won't work and the low fuel light stays on. Can u tell me where "all" the fuse panels are at?


I doubt it is a fuse problem. More likely the fuel sender is not properly connected or the sender wire got cut on a sheet metal edge and is shorted to ground there (this won't blow a fuse).

What makes the speed odometer work improperly?


there is a sender in the fule tank this may be faulty so its not sending the info to the tank gage find the whire from this sender on the fule tank and short it out to the car bodywork the tank should then read full up if the wireing is good, if there is still no reading its likley to be the gage not working, or a broken wire to the sender,,,if the sender is broken it canot be fixed so fit a new one but check how much fule is in the tank before you try to remove the old sender or it may spill out every were, if you fit a new selder only add a gall of fule and see if there is a reading on the gage before adding more so you find out when the tank is realy empty,, never trust the gage to be true

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.

2003 Avalanch fuel gage


You have a problem with the stepper motor gauge that Chevy used in the 02-06? Avalanche. All the gauges use the same stepper motor. They just go wonky and do all kinds of weird things. I have replaced two on mine already and two more are now acting up. There is a guy selling the motors and the repair for this problem on E-bay.
