guys my gas guage isn't working

[whitesswj]

last week my fuel guage quit working on me. First i thought it was a fuse, there isn't one. then i thought it was my hot wire out of the box to the guage and i put it on another terminal and it made a small spark, no big deal, and it hasn't worked since. you guys tell me.
When the key is off the guage goes extremely slowly up from E to like 1/16th of a tank and as soon as you turn on the key it pulls back down to E.
