Not Empty

[blco]

Evening, I have a 03 3/4 ton silverado with the duramax, it has been sitting for a month and not started during that time, weather has been Colorado weather, nothing below 20 overnight. SO he problem is key goes in, lights come on, engine warms up, gages work, BUT NOT the fuel gage, it stays on empty and the empty light stays on. turn the key and nothing, well the lights dim but thats all,

Fuse?
half a tank of fuel when shut down last time

any help would be greatly appreciated,,,,,,,,,,,,,,

Thanks

Any trouble codes? Curious because of similar problems for 2001 - 2005 diesels. See this NHTSA info
