Default Fuel Gauge Quit Working

Any ideas what could cause this to happen, driving my 99 convert. and the fuel gauge stopped, when I insert the key in the ignition the needle moves to the right but goes back to "E", tried adding Techron last night to the gas as read in the Fourm, no changes yet, any ideas would be appreciated....bobkny99

Techron is a good solution but it takes a while.

I ran a can in each tankful 3 different times and then switched to Chevron. Worked for me.

Good things come to he who waits.

Default Techron must be good

Thank you Plasticfan, I pulled many threads from the Forum and sounds like all agree that techron is the real deal, I just added one bottle last night but will follow up with more. Thanks for the response

If it is a fouled sensor then Techron will help. It might take a few tankfuls... Simultaneously switch to a top tier gasoline
www.toptiergas.com

It could also be a bad ground wire
In the worst case (rare) it could be a failed sending unit.

Did you reset the computer? When my gauge dies, I reset the computer and it comes back to life.

that is what I was going to suggest. I had it happen to me once with a bad tank of gas. I had a PCM error code and the minute I cleared it the gauge worked as normal.

It happened to me once, and I reset it, and it was fine after that.

Pull the codes, then reset it. You get to the codes by press and holding the fuel button on the DIC and touching the Options button four or five times in 5 seconds. Then scroll through the various computers for the codes. Write them down before you press and hold the "Reset" button on whatever code. Reset will clear it.

I remembered just now that Bill Curlee posted about a ground connection for the fuel tanks that will come loose too...might cause this.

Well

I put 12oz of Techron in with about 5 Gal of Exxon in the tank.

Then I drove to Shell as per Toptiergas.com and filled up

Fuel gauge works again.

When I got home I put another bottle of Techron in since 12oz only treats up to 12 gal of fuel and the Z06 has an 18 gallon tank.

thanks for the unput on this thread - I thought I was in for $$$$ at the dealer. My wife blamed the Autox 2 days ago saying I probably broke it.
