2001 325ci swap with a 2005 330ci

I have swapped the engines out, flashed the ecu with the 330 tune. It cranks but won't start. I didn't use any parts from the 325 except for the O2 sensor harness. I don't have the 325 engine anymore so I'm not able to swap any more components from it. Any suggestions where to start to figure out what the problem is?
