* Fuel pump relay: This is a more likely culprit. Check your owner's manual or a wiring diagram to locate it and test it. You may need to replace it.
* Blown fuse: A blown fuse protecting the fuel pump circuit can also prevent it from working. Check the fuse box (usually under the hood or in the dash).
* Fuel pump itself: The pump could be faulty and need replacement. This is a more involved repair.
* Wiring issues: Damaged or corroded wiring in the fuel pump circuit can interrupt power.
* Inertia switch: Some vehicles (though less common on the 91 Dakota) have an inertia switch that cuts power to the fuel pump in a collision. Check your owner's manual for its location and if it has tripped.
Instead of looking for a reset switch (which doesn't exist), you'll need to troubleshoot these potential problems. A repair manual specific to your year and engine will be very helpful in diagnosing the issue.
