2010 2.0 genesis coupe - overheated and now wont start! Plz help!

G-320952

Hello everyone, my younger brother was recently driving down the highway with his 2010 genesis coupe 2.0. I think one of the radiator lines blew because he said he saw some smoke but didnt think it was him. The car overheated as he got to his exit and shut off. It wouldnt start. There was an engine error code for the crankshaft position sensor. We have replaced the sensor, new spark plugs, made sure its getting gas, its getting spark as well. Idk what else to do. It will crank but will not start. My grandfather who works on cars said it may have to do with the timing any ideas on what it may be? Thanks in advance!!!
