sounds like a fuel starvation problem to me. could be a number of things. do you have a fuel pressure gauge? have someone start it while u watch the pressure. i bet it drops as soon as the engine starts. obviously low pressure means bad pump or filter. hopefully thats all it is. otherwise.. like i said it could be a number of things

You could find someone that has a compatible ecu and ask them if they can loan it too you. Swap them and see if this helps. Also could be something as simple as a fuel filter clogging or a fuel pump on the fritz..................

If I were you, I would not push the issue, do not try and make your car run by adding gas to the air filter(a car fire is not something you want). Leave the car alone until you find another ecu. Swap the ecu and see if the car starts and runs on it's own. If you are still having issues after that then check your injectors. Good luck to you.

You need to perform a fuel pressure/volume test.
First check and see if you can hear the fuel pump. Near the oil filter there is a wire harness with a yellow 2 pin connector. Bridge the connectors with a piece of wire then turn the ignition to the on position (not start). Go to the back of the car and see if you can hear the fuel pump making a whirring noise. Might just open the hatch and lift up the rear carpet where the fuel pump is.
If you cannot hear the pump then check the EGI main fuse.
