Spraying starting fluid into the filter won't do any good.

Remove the fuel pump relay & air filter housing. Push down on the air flow sensor plate (big round thing) and from about 12" away spray directly into hole. Have someone try to start the car while doing so. If you get nothing, it's more than likely not a fuel issue.
