fuel troubles, wont start Options

[import202]

i fitted new fuel pump n now it wont start it trys but just gettin loads white smoke which if remeber rite is over fuelin or is it ? also does the fuel system need bleedin after fittin new fuel pump because of drainin the system so was thinkin maybe air in there and could it be my fuel pressure regulator as not workin as it a fse boost valve n dont think much to um anyways do u think better off installin the standard pressure reg
