By starter fluid, do you mean ether spray? There should never be any fluid going into an engine. The risk is lock up and broken pistons if fluid gets directly in while turning over. The ether spray goes straight through the air filter, but if you wet the filter, you risk a backfire that will set the car on fire. Take the air filter off and stand well out of the way of any backfire flame. There is no way a car with a faulty fuel injection will keep running though. All it will do is prove the ignition system is working, so you still have to find out why the fuel is not being delivered. If you are using alcohol blends in a very cold climate, and cheating by using ether at startup, then it is time to go back to straight gasoline. I suspect you have an older model carburettor car, that needs reconditioning, so air/fuel electronics would not be be an issue. There is no other way to spray ether other than in the air intake.
