1996 Chevy Blazer S10 where is the fuel shut off?

The 1996 Chevy Blazer S10 does not have a manual fuel shut-off switch readily accessible like some older vehicles. The fuel system is controlled electronically. There's no lever or switch you can flip to cut off the fuel. If you need to stop fuel flow, you'll need to deal with the fuel pump or fuel lines themselves (a job best left to a mechanic).
