I am going to hazard a guess

that it is in the fusebox in the picture under the spot labeled Fuel Pump. I have a 1986 which is located differently, but if I understand what you are looking for, your fuse box appears to be labeled in the spot you predicted. What am I missing?

 

OP, you have a fuel pump relay in that box. make sure it's good. ALSO, some late 80's bronco's had not one but TWO fuel pumps. so sure you changed the external one, how about the one in the tank? some broncos also had a fuel reservoir (which may or may NOT have a filter in it).

also, the search function will uncover a WEALTH of knowledge on not only your question, but the suggestions i made to you. Good luck.

 

Trust me, I loooooove the search feature on this site, thats why I only have 75 posts cause I'm always on here but I can usually find what I need in searching. I can't find exactly what I'm looking for by searching this time. When I use to turn on my truck, right where that external fuel pump is located i would hear it kick on for 2 seconds. Now when I turn the key with the new one installed, I hear nothing.

see that EEC relay too?

87-89; Fuel Injected Engines - "...Two electric pumps are used on fuel injected models; a low pressure boost pump mounted in the fuel tank and a high pressure pump mounted on the vehicle frame. The low pressure pump is used to provide pressurized fuel to the inlet of the high pressure pump and helps prevent noise and heating problems. The externally mounted high pressure pump is capable of supplying 15.9 gallons of fuel an hour. System pressure is controlled by a pressure regulator mounted on the engine

Low-Pressure In-Tank Fuel Pump for '84-89 EFIs

The fuel pump is a motor with an impeller assembly, much like an oil pump, so it will allow fuel to leak backward into the tank when it's not running. This behavior is VITAL to the operation of the dual-function reservoir. Inexpensive aftermarket solenoid-stlye fuel pumps do not allow fuel to leak backward, and so inhibit the DFR. by Ford via Steve83

Operational Sequence; "... When the ignition switch is ON, it turns the EEC power relay ON. The EEC power relay provides power to the powertrain control module (PCM) and the control side of the fuel pump relay.
Power for the fuel pump(s) is supplied through a fuse link or high current fuse attached to the starter solenoid (battery side). From the fuse link or high current fuse, current flows through the fuel pump relay and inertia switch to the fuel pump(s).
When the ignition switch is turned ON, the fuel pump(s) will operate. If the ignition switch is not turned to the START position the PCM will shut the fuel pump(s) OFF after 1 second. The PCM will operate the fuel pump(s) when the ignition switch is turn to START position to provide fuel while cranking. After the engine starts, the PCM will continue to operate the fuel pump(s) unless the engine stops, drops below 120 rpm or the inertia switch is tripped
The inertia switch is located in the cab, generally under the dashboard on the right side; or behind parking brake assy. It is designed to open the fuel pump power circuit in the event of a collision. The switch is reset by pushing each of 2 buttons on the switch simultaneously (some models use switches with only one reset button). The inertia switch should not be reset until the fuel system has been inspected for damage or leaks."
