1989. Where is fuel pump relay and/or fuse located?

This should be in the owner's manual. I found the below on autozone.com, their repair help location:
An inertia switch is used as a safety device in the fuel system. The inertia switch is located in the cab, generally under the dashboard on the right side. 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.
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). The fuel pump relay is controlled by the PCM.
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) 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 fuel pump relay is located on a bracket on the right front corner of the engine compartment. A 12-volt test light will verify whether or not power is getting to the relay. Some fuses are not marked in the fuse box.

Yes try the fuel pump relay first, jumping it will tell you whether or not the pump is working. Though you should hear it turn on ( the fuel pump that is) turn you turn the key to the 'on' position.

the fuel pump relay is normally a black colored relay, located in your fuse / relay box, check for this under your hood located in a black box, on the drivers side. check on the inside cover, it should show a diagram of where the relay is located in the box, hope that this has been very helpful to you.

The fuel pump is in the fuel tank. The tank must be drained and removed to change it. the fuel pump relay is on the passenger side of the engine compartment. It is to the outside of the right shock tower next to a large fuel pump solenoid resister.

FYI: the circuit opening relay is in the passenger's kick panel fuse box. The EFI main relay is in the engine compartment fuse box.

fuel pump is protected by a relay. see owner manual for location.

PCM power relay powers up PCM. PCM then powers up fuel pump through fuel pump relay.

Also, check to be sure inertia switch is not tripped. In trunk. look for label or look in owner manual for info.

in the fuse panel under hood its marker fuel pump relay

there's not a fuse it has a relay for the fuel pump the relay is under the hood in the fuse box,check behind the tank for a ground wire not loose r broken check all ground wires.

Underneath your hood, behind the passenger side headlight, behind the core support, is a bank of 2-8 relays. One of those relays is the relay needed for your fuel pump. There will also be a fuel pump relay fuse located there. The relay designation should be on the cover of the relay compartment.

The fuel pump relay is located behind of the glove box. The fuel pump fuse is located in the same box (Relay Center). The fuel pump relay is either the 2nd or 3rd one down in the 2nd row. You may want to check your computer codes and make sure it is not your ECM or BCM as they can shut down ones fuel pump too.
