    Fuel gauge is reading way over full.

    This happened overnight, I'm sure there is a bad connection somewhere as this is sign of no connection to the sending unit.

You must replace the sending unit in the gas tank to correct this problem, or do you already know this?

What engine? 350? It is in the drivers side head. Between the 1 and 3 spark plugs.

Fairly common problem with GM vehicles. The sending unit in your tank has a small circuit board that an arm is attached to which moves up and down according to your fuel level. This circuit board and arm are not making good contact. Unfortunately the only good solution is to replace this part.

SOURCE: 2000 buick century custom. fuel gauge fluctuates

The sender unit has a fine resistance wire with a slider to read the level, the slider or wires are worn and making intermittent contact, the low fuel light is a seperate switch so it will still work.access to the sender is usually under the rear seat cushon, under the soundproofing and a cover, have a look and describe what you have .

I have the same problem on my 2003 Dodge Ram 2500 5.7 Hemi. Also the gauge is sometimesslow to register after filling. Maybe 5 minutes.My neighbor has the same poblem with his 1999 Durango? I think this is a job for a recall.

SOURCE: temp gauge doesnt work on my 1993 chevy 1500 p/u.

If you only have one wire on the sending unit,the other wire is more than likely an independant ground.

the norm is that if a device only has one wire going to it. is grounded by the outer part of the device.

good luck!

You won't get power at the sending unit. The sending unit provides a variable ground to the dash unit. Where did you ground the dash unit? If you disconnect the sending unit at the tank and ground the fuel gauge circuit there the gauge should go to full. If if doesn't the problem is between that connector and the place you cheched it before. If it does the problem is with the sender. Occasionally new parts are found to be defective.

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.

I have a 1986 chevy 1/2 ton. the fuel gauge wasn't working so i replaced the sending unit and now when the tank is full the gauge reads at only 1/4 tank...any ideas? i was thinking maybe the gauge itself...


When you changed the sending unit, was this in the tank? or does it have a manual that bolts to the block. If it is on the block, drop the tank (or take the bed off) and replace the float.

Replaced Fuel Sending unit on 1986 Chevy Truck


Check the ground wire at the wiring harness at the fuel tank. If it has a good connection then check the power wires to the tank. You may have a bad pigtail going to the tank. A replacement harness is available at NAPA.

When replaced the fuel send unit the fuel gage sits on empty


Try grounding the gauge wire at the tank. If the gauge and wiring are good the gauge will go way past full when you do this.
