1986 GMC Safari Gas Guage Stuck on Full

Hi there, I have a 86 safari and my gas guage is stuck on full. Once in a while it'll will work for a day then go back to full. I don't know what it could be but I really need it fixed as I drive my baby around. Any ideas, cheaper ideas? Also my interior lights are not working but the fuse is fine can't figure that one out either not really a biggie though because I don't drive too much at night but help would be appreciated. Thanks

Fuel Giage is Controled By A Reostatic Sending Unit In the Tank that Has A FLOAT to Fallow the Hight of Fuel in The Tank If it Gets Stuck This is what will Happens. I would Advise you to Replace it With A NEW ONE from Dealership They ARE a BIT PRICEY But given its Usefullness its Well Worth it Especialy With a Baby Riding along lots.
And The Exterior Lights This is Fairly Simple as there is A PARK LIGHT > Fuse and if it is Good Chances are your Headlight Switch is Bad.

Your fuel sending unit is bad. This is an electronic component inside of the gas tank. Many times the metal bar will rust and get stuck while there may be nothing wrong with the actual electronics, which is what it sounds like you have here. There is no cheap alternative to fix the problem correctly, however you can beat on the outside of the gas tank and it may free up the arm that is rusted.
I hope this helped, please remember to rate this answer.

Gas guage on my 1995 GMC Van reads full all the time.. what makes that happen?


Sounds like a stuck float, there isn't a whole lot you can do unless you want to drop the fuel tank and throw a bunch of money at it.

Gas Gauge Inaccurate


Sounds like the 'float' is stuck. This is a small lever in the top of your fuel tank that rests on top of the fuel. When the fuel level drops, so does the 'float' and then it sends a different voltage to the guage, which in turn shows less fuel. It's an easy repair, but requires dropping the fuel tank to get at it. If your not experienced with this procedure, most any repair shop can do it. Try to run out most of your gas first, though, so that you don't 'lose' it at the garage! Good luck. Let me know if you need directions to do it yourself.

Gas guage stuck past full mark(1996 gmc jimmy)


hate to be the bearer of bad news but you asked
you will have to drop the fuel tank and pull the float assembly out and you can try to clean it up but it usually is only a temporary fix

My gas gauge is stuck on full in my 2000 ford mustang


You will need to locate the wire to the fuel sending unit at the fuel tank.

Once you locate the wire, disconnect it and see if the guage goes to 'E". If the guage goes to "E", you probably have a bad sending unit.

To double check, ground the same wire to clean metal on the frame with the key in the "on" position (not running). If the guage does not move, the guage is bad. If the guage moves from E to F, the sending unit needs to be replaced.

Fuel gauge stuck on half full


I can tell you almost for certain your fuel level sending unit is bad, I have been able to fix them though. It requires removing the gas tank and then the fuel pump. You can if your inclined, bend the brushes on the small circuit board over more so they will make better contact on to it. Other wise its a new fuel pump assembly, check all plugs and wiring by unpluging and repluging them to insure no bad connect. It is possible it could be the guage itself, but in thirty years of fixing cars never had a bad guage
