Where is the fuel shut off reset switch 1999 f-150?

There isn't a fuel shutoff reset switch in the common sense of the term on a 1999 Ford F-150. Older vehicles didn't have these as a standard feature. If there's a fuel-related problem, it likely involves:

* The fuel pump relay: This is a more likely component to need attention if you're having fuel delivery issues. This isn't a "reset" switch, but replacing a blown fuse or relay will restore function. You'll find the location of your relay in your owner's manual or online by searching "[your year] F-150 fuel pump relay location."

* The inertia switch: This is a safety device that cuts off fuel in a collision. It might have tripped and need to be reset. This is usually found under the dash, often near the driver's side. It typically has a button that you press to reset it. Check your owner's manual.

* A blown fuse: Check your fuses, specifically any related to the fuel pump or fuel injection system. Your owner's manual will show you the fuse box layout.

* A faulty fuel pump: This would require professional diagnosis and repair.

If you are having fuel delivery problems, rather than looking for a reset switch, focus on checking these other components first. A mechanic can help diagnose more complex issues.
