Car will turn over but it sparks idk what the problem is now..?

Okay at first i had to change my distributor on my 93 Ford Probe GT cause apparently the control module had gone bad. but i changed it.... went to jump my car and put the cables on backwards(yes i know it's stupid and yes i know how they go black always on negative but i wasn't paying attention) So I tried starting my car after i properly charged the battery... and it started smoking.. wires did. and there was really big sparks coming from my the ground where my battery cable is connected to the fuse box. seems as if theres a short or something... it did blow the main fuse and ignition relay when i switched the cables around.. i did replace those.... so i'm thinking that there is to much electrical current traveling through the wires making the hot and causing the smoke? i'm no good with electrics but i know cars. Before i replaced the distributor it wouldn't turn over at all... but now it will after i replaced it so i expected it to start but i did this. idk what i did but i need to know what you mechanics think.Car will turn over but it sparks idk what the problem is now..?
well first you proably fried your computer brain by jumping the battery backwards first get it checked out with a scantron ask the parts house if they have one you can use next if the computer is fine make sure all your wires are connected including the coil wire make sure of all of your concections are conneceted if that doesnt fix it post anthor question and i will ansewer it
