1994 Ford Taurus My daughters car wont start!

My daughters car (94 Taurus) stopped running the other day. I checked it out and so far have found that the injectors are firing, the fuel pump is priming and sending fuel, and it fires temporarily when starting fluid is shot into the throttle body. A guy at the parts store talked her into buying a new fuel pump, but I picked up a new fuel filter for her and in the process determined the pump is fine. I had her turn on the key while I was under there and the pump shot fuel through the line giving me a gasoline bath. The gas seemed to smell like "gas light" as I called it so I had her buy some HEET to dewater her fuel. She also picked up some heavy duty stuff that is supposed to be even better and we put that into her tank. Car still doesn't want to start, though it cranks over fine, but will fire if starting fluid is injected into the throttle body. Where should I go next? No check engine light is showing. Any help would be great.
