the reset fuel switch on my f350 is located where

I know of no re-set fuel switch on your truck. In the old days ( 1980s-early 1990s ) there were inertia switches, in the case of accidents, to shut off the fuel pump, but electronic controls made those obsolete years ago. If yo suspect a fuel pump problem, check the fuel pressure and make sure that you have 12 volts at the fuel pump connector when the engine s being cranked, not just with the key turned on.

Reset the switch by pushing the reset button on the top of the switch. The reset switch is usually accessible through an opening in the kick panel or by reaching over the top of the panel.
