Help me start my car!!!!

We were working on my car in class the other day and someone grounded out a connector. Well, at the end of the day I went to start my car and it turned over but didnt fire up. Its getting spark but one thing is really wrong, the ecu isnt getting power. I thought maybe the ecu was fried so I tried my other ECU but it didnt get power either. The fuses are fine. I dont know what else to do. Please help me out.

If it's not getting power, my guess would be a fuse or wire. Did you check the fuses under the hood and the ones under the dash, and did you just look at them, or test them with a multimeter or a test light?

I used a test light. I think its a bad wire though since everything else seems to be fine.
