So just recently my sentra has been running odd when I try to start it. It either doesnt start like it normally should, or it starts then dies within a second. I replaced the O2 censor in it, I have a decent mechanical background so I believe I did that right. The check engine light stopped coming on after I replaced the censor, but now im lucky if the car will even start. I've checked it for vaccume leaks, but I cant find any. I dont know what else could be wrong with it.

Check the mass airflow sensor, if not we'll have to start with the basics. Spark and fuel.
