I just noticed today that occasionally the gas gauge will drop to completely empty. I imagine that this is a wiring issue or a sending unit issue. Is this a common problem? Can someone point me in the direction of a fix? I know this is a pretty common problem on the old Dodge Ram's but not Chevy's. Thanks!

 

it wont be long until the gas guage will go back and forth between full and empty for no reason

its the fuel sending unit i twent out in my 99 and i just went by the trip odo

 

mine does it to ive been told its no big deal

 

Yea, the sender in the tank seems to be the common failure.

 

mine also does that......but only goes back when I put more gas in

 

yup mine does it too,, what a pain in the *** !!!

 

Dude...the problem is your Fuel Level Sensor which is connected to your Fuel Pump Module in the tank.

If you get me your Vin # I'll shoot you the correct part number.

 

Mine's been doing it for about a year. When it was under warranty they were supposed to fix it, that lasted until about two years after the warranty. Expensive little suckers!

 

My buddies Cobalt does that. What he does is gets it up to about 20mph, puts it in neutral and then turns the car off. Waits for a few seconds then turns it back on. I almost died the first time he did it. Then I remembered it was just a Cobalt anyway. It works though.

 

It could also be the cluster, my brother has an 01 and his did the same, he had to put a new cluster.
