If it starts with starting fluid you aren't getting gas. Your fuel pump could be bad or clogged fuel filter.
get a fuel pressure tester, and test the fuel pressure at that fat valve on the fuel rail.
when you first turn the key to run, (dont start it, just turn to run) can your hear the pump prime? have some one in the trunk to listen for it, it will hum for about 3 to 5 seconds.
could be a really clogged filter as well.
will it stay running after it starts with starting fluid?
or does it start and stall, like it ran out of starting fluid to run on.
take a rag, put it over the big valve on the fuel rail, push the center of it with a screw driver, if you have any pressure, gas will shoot out, fast. the rag is to keep it from getting in your eyes. inside the valve looks like a air valve on your tires, but larger.
checked all your fuses? under the hood and in the car?
seams like your injectors are not firing at all.
you can take off a injector plug, use a test light to see if it flashes, or stick a side marker bulb im told works, right into the injector plug, and if it flashes its getting power. (push the metal clip in on the plug, and wiggle and pull up to take the plug off the injector)
it should flash when you first turn the key to run, and then after its running it should flash. 2 person job maybe.
Has the Idle Air Control Valve been checked? If you've got fuel and spark (which I take it from the conversation so far you do) then the only thing missing is oxygen. The throttle plate is closed when starting so the IAC meters air into the engine so it can fire up.
