First of all, using starting fluid on a fuel injected car is a no, no.
The reason being, your computer can only account for fuel being fed to your engine through the injectors. And any additional fuel will make your engine run overly rich, if for only a brief few seconds. This can cause some damage to your cylinders, O2 sensors and catalytic converter. Also, your intake isn't designed to flow fuel (Fuel is injected at the backs of the valves and directly into the cylinders), and by squirting starting fluid in the intake, you could cause a backfire, which may destroy your mass airflow sensor.
Now, your engine will still crank if your timing is off. (Ignition or valve timing)
But the first things to check when you have a "No start" issue is spark. Then if you have spark, you check fuel pressure. If you have fuel pressure, you then check that your injectors are firing. If your injectors are firing, you then check for compression. If you have no compression, then you know there's a mechanical issue with your engine, and a tear down is in order.
At any point in this testing procedure you run into a problem, then you've found the offending system and you work your way through that system until you isolate the cause.
