If you are referring to the little engine shaped light, you need to stop throwing money at it, and start with the proper diagnostics.
If you don't have a trusted mechanic, go to AutoZone, Advanced Auto Parts, Kragen, (or????) and ask that they retrieve the diagnostic trouble codes, and give you the list. Write them down.
Go to the library, or while you are there, purchase a repair manual and read a bit to learn what circuits are involved in the diagnostics and subsequent repairs to eliminate the code(s)
It is possible that a missing or malfunctioning fuel cap could cause the light to stay on.
But start with letting the computer (which controls that little light) tell you why it has illuminated it.
Good Luck

Assuming you mean by fixed everything you mean you took it to a competent shop and they checked the computer codes for a fault and fixed it, they should have reset the code, so the light went out before they returned the car to you. If it keeps coming on after, and all is OK you may just need to fully tighten the gas cap. As this will set a fault code in the computer.

Most likely it is a faulty relay in the cars central computer. This would be a very expensive repair as they would replace the computer, were talking thousands and not worth fixing! Any trustworthy repair center can test this for you for about $30 and some will test it for free!
