Power problem

I used a code reader and ended up shorting the OBD-II port. Now car has no power to the lights, fuel pump, fuel injectors, radio, and some of the fuses and relays in the engine compartment fuse box. I took the positive battery cable completely off and did not see a fusible link though I see mention of it everywhere online. My daughter is about to start college and I really need to get it fixed. Please help.
