Sounds like you have a bad fuel scensor this is something most people would have a licensed mechanic fix!

SOURCE: 2002 Chevy Suburban: Fuel gauge reads empty, tank is half full

Youre gauge is controlled by a plunger in the fuel tank which is attached to the sensor and the fuel gauge. it sounds like when the plunger goes down half way its either getting stuck down lower then it should. Needs replacing. Any mechanic can do this install for you.

2003 Chevy S10 had fuel pump replaced. When fuel gauge shows slightly below half, the gauge falls to empty and low fuel lights blinks. What could be causing this?


hi,

sounds like the sending unit rheostat(sending unit) has a bad contact or break in the resistance wire. inside the tank theres a float attached to an arm that goes to a small rheostat, like a volume control on a stereo. the rheostat is sending a scratchy signal or no signal to the computer and your getting these readings. that part is inside the gas tank, the part usually comes integrated with the fuel pump. the gas tank has to be lowered to fix it.

How do you remove gasoline from the gas tank of 2003 chevy tahoe


You'll have to drop the tank while it is full... It sucks too. My advice is to get some help. It'll be heavy.

Gas gauge malfunction and engine light stays on


This is a common problem with Malibu's. It is due to cheap metal in the fuel gage that corrodes. Chevrolet knows about this but they refuse to issue a fix. The check engine light staying on and the faulty fuel gage are related. This is a defect and they need to recall this part! Raise hell with the dealership!

Engine stalling on a 2002 chevy tahoe z71


Still sounds like a fuel problem. Try a full tank of supreme gas, plus put a can of SEAFOAM into the tank to help clean you injectors. See if this will help clear up your problem. Did you change the plugwires????
