I would check the stator(hall effect switch) in the distibutor.

SOURCE: 1991 ford f-150 fuel pump will not come on

remember the switch only gets power for 1 second when u turn the key on, the common problem is the ignition starter switch comes apart, it is located at top of the steering column near the bottom, drop the column down (2 nuts) and inspect the switch for separation.

SOURCE: 91 ford ranger...fuel pump will not run pump is good

It won't hurt to jump sire to drive, It is designed to pump all time when the engine is running. The only problem is the pump should not be on if engine is not running since it is designed that way to prevent a fire while pump continues on once engine is stops in a car accident. There is a control device to immobilize the fuel pump, if there is no speed sensor signal from the crankshaft. This needs to be located and fixed.

Fuel shut off switch should be located in the trunk on the same side you fill your tank on. The switch is guarder and you will have to figure out which way to press it
