UrdnotWrexSTi will become famous soon enough

My AP turns on and connects to the ECU so I’ll be able to unmarry it, so that’s not a big deal. I’m just not skilled with diagnosing wiring/electrical issues. All I can say for now is that my entire injection system is down. Fuel pump doesn’t turn on and no voltage at the injector plugs. I’m thinking I find a used ECU that matches my car and plug it in and see if it turns on the fuel pump and I get power back to the injectors. If that’s the case then my ECU is the issue.
