Hi,
The idea that it sputters with starting fluid leads me to believe it has spark to the plugs. However, I need you to confirm that. Here is a link that explains how to test for spark. Do this first.

If you find there is spark, I need you to next check for power to the fuel injectors. If you look at the pic below, note that each fuel injector has a white wire with a red tracer. That is the power wire for each injector, and it should have power when the key is in the run position. Check any of the injectors' white wire/red tracer for power. If there is power, then we need to move to the PCM. The PCM is what provides the ground path to complete the circuit and actuate the injector at specific times and lengths.
Here is a link you may find helpful when checking the wiring:

Let me know what you find.
Take care,
Joe
