First, I attached the wiring schematic below for the powertrain management circuits. I highlighted things related to the fuel pump.
You mentioned the fuse was good for the EFI. In addition to checking the fuse, did you also check for power to and from it? Here is a link showing how it's done:
Next, when the ignition key is in the run or start position, power is sent to the coil open relay under the dash on left side. The power is supplied via a black wire with a white tracer. When power is applied, the contact which sends power to the fuel pump actuates and sends power via a black wire with a red tracer to the pump.
What I need you to do is this. First, go to the coil open relay. Turn the key to run and check power to the black/white wire. If it is there, check the black/red wire out for power.
If you haven't checked the relay, switch it with one having the same part number to see if it changes things. Or here is a link that explains how to test a relay:
If there is power at the black/red wire and you don't get it at the pump, you must have a broken wire at some point.
Let me know what you find or if you have other questions.
See pics below. Note: the schematics had to be cut in half to make them readable for you. I did overlap them so you can follow from one to the next.
