Fuel gauge stuck on Empty

[Shaye123]

Hey
My fuel gauge has been stuck on Empty for quiet a while now, filling tank dosent change anything, tried to do a system check and upon doing that the fuel gauge did move up to halfway so i know its not the cluster itself, but after turning car off and on again it is still stuck on Empty. Any ideas on how to fix this? Cheers

Is there an codes displaying ? If not its now a process of elimination,

Check any of the plugs/connections under the car first,
Get hold of a Tech2 / or any other Diagnostic Unit, and do a Cluster Fuel Gauge Test, that will show if the gauge is working correctly, in the range of Full and Empty, if not a Replacement Cluster.
Otherwise, it sounds like a "Tank Out" and replace the Pump/Sender Unit
If you go that far, best to replace the complete unit.

What you can do, is check the gauge sender unit resistance manually with a multi-meter, depending on the fuel level.
On the other hand, if the Tank unit is ok, probably a dash repair or replacement.
Here is a link that may be able to assist.
