the problem is not the crank angle sensor.
you said your car runs when you spray starter fluid into the intake, so the engine is sparking.
the ECU uses the same RPM signal (crank and cam sensors) to fire the coils and the injectors.
the problem is:
the injectors, all 6 of them (FIX = REPLACE INJECTORS) --unlikely
the ECU controlling the injectors (FIX = REPLACE ECU) --somewhat likely
the wiring to the injectors (FIX = CHECK THAT EVERY INJECTOR HAS A SIGNAL PULSE AND SWITCHED 12v AND REPLACE WIRES IF NECESSARY) --most likely
does any of this make sense?
you're in over your head.

where is the ecu that controlls the injectors??

The ecu that controls the injectors is the ecu itself. It grounds the injectors which then fires the injectors. Looks like you might have a wiring issue, but check the injector fuse in the engine bay fuse box to see if its blown.

Ok. here is my turn. I would not trust any if the wiring since you didnt do it. Unplug the injectors, all six. check the polarity and see which side is getting ground and positive. write that down. now run NEW wires to the injectors, all six. wire them in batch mode, which is 1-4, 2-5, and 3-6. In other words when you run the wires, wire those together but on the trigger ground side. you can leave the positive side on the injectors from the stock wiring harness. if you still dont trust that, then run a seperate relay triggered on by the kick panel, then trigger the injectors that way, the way i did. does this make sense. if you run new wirez and check for ohm resistance and power, you have eliminated one less problem. if you cant figure it out, i will call you when i am back from vacation.

Hang in there, i know it is frustrating ... believe me i know. try to check to see if there is any resistance on all the injectors. Then try my method. That is what me and Cartmill had to do.
