Fuel pump shut off switch location?

I hit a deer with my van and now it won't run very long before stalling. It acts like it isn't getting fuel. The hit wasn't very bad. Dented the right fender, but not hard enough to cave in the inside. The manual says it could be the fuel shut off switch, but doesn't tell us how to reset the switch.

All help will be appreciated.

Sincerely,
Kelcey
