If it runs on starting fluid, then it isn't getting fuel. You mentioned it has good fuel pressure, it's most likely not getting power to the fuel injectors or injector pulse from the PCM.
At each injector, there will be a pink wire. I need you to check for power to those wires. If there is no power, check both injector fuses in the under-hood fuse box.
If you find they do have power, I need you to disconnect one of the injectors. The connector will have two wires, one pink and one another that is different based on the cylinder.
Take a test light and place one end to the positive side of the battery and the opposite side to the wire (not pink) in the injector connector and have someone crank the engine. The test light should pulse on and off.
Let me know what you find.
