Question about 2004 Ford Taurus
If it will start momentarily with a small spray of starter fluid
(ether) then you know the ignition system is ok. But, the fuel delivery system is not. If you can get the car to a Car parts store, they may agree to read any ECU error codes. That may give you some help in understanding problem sensors or the connections to the sensors.

You say you had 3 mechanic's look at this and they can't find anything wrong .
Well if it cranks you know the battery is good and you likely don't have a problem with the chargeing system its charging the battery.
This leaves the air intake system No air it won't run .
Or the fuel system no fuel the same .
Or the electrical system no spark or weak spark won't start .
What you need to do is to start testing the systems .For instance take the air filter out . try to start still dosn't start its likely not the filter
Next check the electrical take a spark plug out plug it back into the plug wire touch it to the engine block or any metal that would ground it crank engine over see if you get a good blue spark you will hear a snap if its ok you have to listen and see the spark .Spark yes it works .Not spark the problem is in this system
Next the fuel system witch is the most likely cause for no start condutions you can remove the fuel filter if you can't blow through it its cloged .If not put a plastic bottle over the fuel line comeing from the tank turn the key to run gas should start coming from the pump to the bottle .If not the pump or the pump relay or a electrical connection to the punp isn't working .
If you can check or have someone else check the for you .I could give you a lot more detailed information .
Their's just not enough information to speculate at this point
Best of luck

Your problem might also be your coolant temperature sensor. Yes I said coolant sensor. You can either replace it yourself or have a mechanic check the value like temp and voltage of the sensor with his scanner. If the temperature is low and the voltage is high replace the sensor. That's probably why the three Mechanix you had looked at it could not find the problem because they weren't checking for the coolant sensor.
