Hi,
The ECM1 fuse in the under-hood fuse box is responsible for powering the fuel injectors and the ignition coil. You mentioned power to all fuses. Confirm there is power out from that fuse or go to any of the pink wires at the fuel injectors and with the key in the run position, check for voltage. Also, there will be a pink wire at both the ignition coil and the ignition control module. Check there as well. If the computer doesn't see ignition, it will shut the pump down.
Next, at the ICM, there will be a black wire. Check it for continuity to ground. The part that is confusing me is you mentioned it ran with starting fluid, but there is no spark. Are you certain there is no spark? If there isn't, the vehicle shouldn't have run at all.
I attached the entire wiring schematic for the powertrain management system. I highlighted the wires related to the fuse of interest. Use this as a reference. Also, here is a link you may find helpful.

Let me know what you find. Note: If there is power to and from the aforementioned fuse but the components are not getting power, suspect an issue at the giant splice after the fuse, S132.
Take care,
Joe
See pics below. Note: I had to cut each schematic in half to make them readable. I did overlap them so you can follow from one to the next.
