two days ago i was doing a good second gear pull and the car lost all power. couldnt get it to start and it was late so i had a buddy tow me home.
when i went to start a diagnosis the next day i noticed that my #3 injector was leaking like an open faucet from the top of the rail. pulled it out, replaced the chewed up o ring that was on it fixing the leak and what i thought was the problem but the car still refused to start. pulled the rail today and found out that now none of my injectors will fire.

did a good amount of searching and couldn't find a similar situation (aside from those that had just done the swap and had their fuel lines backwards)

can a leaking injector cause damage to the electrical system somehow?

hoping im not looking at fried ecu.

have spark, good fuel pressure, compression, no ecu codes.

I would first check the voltage to the injector connectors. Then check the resistance between each injector's pins to see if they are all close to each other.
