b20 hatch running extremely rich

[ownzorzed1]

Hi guys I just finished swapping my b20b I started it up and it ran great I drove it a few blocks to my friends house shut it off and when I went to start it and leave it sounded like it was misfiring and smelt like fuel I drove it back and it would sputter until about 3000 rpm then it would smoke a little and u could see it spitting gas out of the exhaust I am pretty new on swapping cars and I had Lots of help from my local tuner friends. There is no jumper harness to check ecu codes but some are saying it's wiring others are saying it's censors they said it could be injectors also please. Help

Need more info to give any kind of help. Year of car, year of motor, stock or built, stock injectors, wiring harness and ecu being used?? First thing I would do is basic stuff like check all connections, grounds ect be sure nothing came loose or got left loose.
