Hello my name is Dave.
Unfortunately, it sounds like there is a chance your ECU has an issue. my first suggestion would be to check the injectors for power and signal. I have attached a link to our tutorial on testing the injectors. I suspect you will find they are not getting any signal and/or power. If you are getting power to the injectors that would indicate that you have power to the ECU, here is the link to the tutorial:
If that checks out to be okay I would move on to testing for fire. I have attached another one of our tutorials on testing the coil for fire.
If either of these tests fail the most probable cause would be the ECU however there is a chance there is a wiring issue. I have attached the wiring diagrams for your car's ECU. I would test all the power circuits for continuity to ground with a volt ohm meter with the ECU unplugged and if you have any that read less than infinite (no) continuity you would need to repair that circuit, if you find that none have continuity to ground than I would feel confident in replacing the ECU. I have attached a link to our tutorial on testing wiring.
I hope this helps you find your problem and thank you for using 2CarPros. please feel free to ask us anything else you need help with.
