Ummmmm Help?

I got this 97 integra right? well Im taking off my exaust and I thought my new GReddy came with the Cat so I took that off also and noticed it had an 02 sensor on it. Well I got to lazy and figured the connector was under the carpet somewheres and the heat sheild around the sensor itself wouldnt let me disconnect it from the Cat, so I decieded to cut the wires and put them back together later... stupid I know but I did it anyways. Now its all back together where it came from and the car wont start... it worked for a liiiiiiiiiiiitle bit... like 5 minutes little bit and then died on me. Its not getting a spark or fuel through the lines... what should I do? Im thinking somthing with the computer and/or fuses.. HELP ME PLEASE!!!

man you cut the wires to the o2 sensor on the cat.
Your problem is the o2 sensor maybe and next time just look above the cat and there is a connection there and all you got to do is disconnect it.

yea we realized where the plug was after we had cut it....
