2002 Pontiac Grand Am frustrated beyond all belief

ran out of gas, got some more, would not catch, thought maybe some air was in the line. got starting fluid, car would run on the fluid and then stall, not getting any fuel, I figure. so turn the key, listening. i hear the fuel pump, so that is working. figure maybe fuel filter is clogged. change fuel filter, still won't start. check the inlet side of the filter, to make sure fuel is getting there. hear a hissing sound, then fuel comes out. try to start again, not working.. should i try the starting fluid again, or is something else wrong? thanks
