Don't worry about the proper "punctuations (and words)"...We know you're frustrated and need help.
I googled "fuel shut off" and found this as quoted below.
"Mounted to the inside of the passenger fender by the air filter housing. It's a black circle switch. Just push the center of the button."

And one on a 2003 Sorento posted to this forum.. by "KIAMECH" he's rated as expert.
"Yes there is, and it's located on the passenger side inner fender, under the hood. If it was tripped, push down in the center of the rubber that waterproofs the switch."
It sounds logical as my 2006 KIA spectra has one located in the engine compartment mounted on the strut tower BUT on the driver's side. It is black and has a black rubber "boot" (like a baby bottle nipple) over it. You just push in on the center of it and that resets the shut off.
Post on my model Spectra on the web...
"There is a shut off fuel switch on the 2007 Kia spectra. It is a rubber covered button mounted at the top and rear of the left shock tower. Press down on it to restore the fuel flow. "
If the Spectra has one the more expensive Sorento should have one as manufacturers tend to skimp on lower end models NOT higher end ones...
