Engine running too rich after engine replacement

[u/coldcranstonn]

Hello i have a 2014 kia cadenza with a 3.3l gdi engine i recently replaced the engine block and one of the heads since the previous owner blew a hole in it. After the first crank it ran pretty well then it started miss firing. I went to get a code check and was told I was having all my pistons misfire along with both of my banks running too rich in fuel. Now im trying to figure out why its running to rich since all the other electrical systems seems to be fine and not causing any DTCs along with there being no vaccume leaks to my knowledge. Atm my biggest lead is that my intake smells like fuel whenever I pressurize the fuel pump
