SOURCE: 2002 Avalanche gas gauge problems

Gm has a real problem with fuel tank sending units. That is what is wrong. You need a fuel tank sending unit. You can only get them aftermarket with the whole fuel pump module, but you can buy them seperate if you buy it from the dealer.

SOURCE: gas gauge quit working just shows low fuel light

This is a case of the sending unit being bad, this is very common on these trucks, this is like a toilet float, it floats inside the tank with a sensor at the base that controls the gauge, hope this helps,65a8465.jpg

This is caused by a defective fuel level sending unit inside the fuel tank. To repair the problem you must remove the fuel tank from the car and replace the fuel pump module which is part of the fuel level sensor.

I would guess you will have to replace the sending unit in the tank. A mechanic can check the sending unit with a meter and find out if the sending unit is faulty or the gauge on the dash.

to clarify, are you getting spark (even when it doesn't start?) My vehicle (1990 grand voyager 3.3L) does the same thing. Sometimes starts, sometimes not but may (or may not) in a few minutes or hours, etc.. Always has spark. So I have a "fails to start" of about 33% which means it is unreliable to drive and not be stranded somewhere. I've been chasing this problem for months, but my workaround is to carry ether/starting fluid. Squirting a little into the intake (open the air filter box) and it ALWAYS starts when cranked. Otherwise the van runs fine (strong performance, good milage, etc.) It's just starting without help that's unreliable.

I know the ballast resistor is bypassed when cranking to start (and in the circuit for regular operation). This could be my problem and I'll look into it. The ether is easier to ignite than gasoline fumes.

check for fuel pressure and volume test, if good then I would not change the pump, but look as far as the ESC (electronic Spark Control) located below the coils. good luck!
