Will turn over but wont start

Thank you for your answer. I found the paper work for my car this is what it said check car for cause of crank no start found engine computer disabled not allowing the engine any fuel cleared codes and preformed reset procedure road teasted running normal. There was an egr code and will check at later date if needed. Do you know what that may intellectually and probable cost for something like this.I trying to help myself and cut cost because I just spent 700.00 on other things with car unrelated. I really appreciate your help thank you so much for your time
