Fuel gauge going to empty.

[zach2011]

My fuel gauge has been acting funny. No matter how much gas I have left in the tank, the needle will randomly shoot all the way to empty and the DIC screen will show "--- MILES" instead of say "247 MILES"...then about a minute later it will go back to the correct reading.

I've read that it may be the sender unit...is that what you guys think?

I'm new to this forum and SUV's. But, have owned a Vette for several years. I spend a lot of time on corvetteforum.com. Some of the older Vette's had/have a lot of trouble with their send units. Same symptoms as yours.

General consensus is that it is a sulphur problem. They believe that using Chevron with Techron helps loosen it up and will often fix the problem. Don't know if it would help you but .....maybe worth a try.

Thanks for the info, I will see if that fixes it. I'd hate to spent $200 on a new sender unit if this fixes it.

Just had that very same problem. It was the sending unit. Easy fix.

 

[zach2011]

Yeah now that I think about it, I might have to do that. I realized we don't have any Chevron's nearby that I know of. How much did your unit cost?

 

[mike06train]

I paid $190 for a new sender.

I read somewhere that Chevron Techron Fuel System Cleaner will sometimes help the problem.
