Welcome to the forum
Fuse for fuel pump is in the engine bay fuse box.
In 1994 is was #22, 20amp, but should be labelled FP Fuse
There is also a Fuel Pump Relay in same fuse box, pull it out and swap it with WOT relay, or just pull it out and have a look at it then put it back in, could just be poor connection in socket.
AND.............in the passenger foot area below Glove box will be an Inertia switch.
Looks like this: http://www.explorerforum.com/forums/...tch-jpg.77025/
Has a Red button on the top
This switch can also be behind passenger side Kick panel
Red button will popup if there is a sudden stop, i.e. accident, this cuts power to fuel pump to prevent a fire.
If it ever "popped up" it can be pushed back down to get pump working again, but..........it is not a full reset, so slamming a door or hitting a bump can pop it again.
So if popped it needs to be replaced.
Fuel pump only runs for 2 seconds when key is turned on, i.e. fuel pump relay only closes for 2 seconds with key on.
But it does that EACH TIME key is turned from off to on.
So repeat as much as needed to see if pump starts to work again, doesn't hurt anything.
1993 uses OBD1 computer so in the engine bay will be OBD1 diagnostic port, image seen here: http://www.therangerstation.com/how-...ipped-engines/
ON the drawing you will see Fuel Pump slot IDed
If you Ground that slot it will activate the FP Relay whenever key is on, FULL TIME so no 2 second thing
