start wont start

i own a 94 integra ls, and last night was a hassle for me. on a red light, the car died and wont start up. i had to tow it home after waiting almost 10hrs first trying to fix it aside the street, one tow guy flake on me, then had to go back home and call another one. even, the tow truck was too big that they couldnt put it in my drive way... couldnt leave it on the street because it was street sweeping that night. my mom and i spend a tiring one hour pushing it up the steep-azz drive way but now that the car is in the back, i'm trying to figure out what happened to it. okay the car wont start, and i had a friend come over to take a look at it. he opened the ecu box, and found the ecu fuses blown, and then he put a new one and got me to start the car...it blew another one up. on the box it says that, that ecu uses only 15amps and we tried putting a 15 or 20amp and still blew it up. he came up with a conclusion saying...there's a short circuit somewhere in your car causing the fuse to blow up. we did test to the spark plug to see if i was getting sparks and yes it did...another mechanic said fuel isnt being sent. and later that night, my brother called and said he did something with the HO2 Sensor, the one connected to the catalyct convertor... so yea, that's all the information i have and will anyone point some fingers on where to look or what had happen? ty
