After a few hundred miles the gas gauge will drop to zero. After another few hundred miles it starts working again. I can reset it by disconnecting the battery overnight. Disconserting at the least! Would appreciate any ideas. Thanks.

add some techron and that will usually fix it

There are a lot of threads on here about this problem. This is being caused by carbon buildup. Buy a can of Seafoam and add to your next fillup. Should fix your problem. :thumbsup3:

I have been having this problems for years now and usually a few bottles of techron thru it clears it right up. now for the last month nothing helps I've been thru 4 bottles of techron and a a bottle of sea foam and nothing helps. i reset the codes and the gauge will regester for about a half mile then drop to empty. i think the sending unit finally gave up???!

sooner or later almost anything and everything fails

Agree with Dawg and Vettex2. Damn I hate that emergency room. Us old guys know what I'm talkin bout....LOL

This is a GM known problem caused by high sulfer content in the fuel. The sulfer causes a build up on the sending unit contacts, causing it to fail.
Changing fuel brands to one with a lower sulfer will slowly correct the problem. Adding Techron, or SeaFoam simply cleans the contacts more quickly.

GM Fuel System Treatment PLUS
GM Fuel System Treatment PLUS, P/N 88861011 (for U.S. ACDelco�, use 88861013) (in Canada, 88861012), is now available.

Added Benefits and Uses
The PLUS portion of GM Fuel System Treatment PLUS is the addition of a filmer additive that, when used regularly, can protect fuel system sending units from the corrosive effects of certain sulfur contaminants found in some of today's gasoline.

Sulfur contamination can disrupt electrical continuity of certain fuel sending units and lead to erratic or false fuel gauge readings. With scheduled usage, GM Fuel System Treatment PLUS protects against the effects of harmful sulfurs in gasoline.

You Get Four Benefits
One bottle of GM Fuel System Treatment PLUS added to the fuel tank at each oil change:

� Cleans -- Sulfur corrosion from fuel gauge sending units.

� Prevents -- Harmful sulfur components from attacking sensitive fuel system electronics.

� Protects -- By coating metallic surfaces of the fuel system.

� Removes -- Engine deposits left from use of poor quality fuels.

GM Fuel System Treatment PLUS will replace the original GM Fuel System Treatment, P/N 12345104 (in Canada, 89020804). The original formula may still be available for a limited time, and provides the excellent Fuel System Cleaning aspects of the new product without the filmer.

NOTE: The interval for using this cleaner is 3000 miles.

Sadly true.:soapbox:

I used a bottle of Seafoam after using two bottles of Techron that did not help,the Seafoam worked on the same problem in my F-350 Diesel.

I tried sea foam as well with no luck. Thinking abou trying the GM stuff but that looks like a re packaged bottle of techron.

techtron worked for me and I use 93oct fuel from BP has not acted up in almost 2 years:thumbsup:
