Help!!! code 30BA AND 30BB!!

I need your help guys!!! I dont know what ta fack is going with my car anymore lol. This will add to the many weird stories about N54s. So I decided to change my valve cover gassget. I was very careful in taking everything out and keeping track of what cylinder it went and so on... got it all back together and fired her up... ran like shit.. then I noticed oil coming out by 5 and 6 ofcourse and yes it was allot of oil fml....and then the car just died. Didnt want to turn back on. I took her apart again the same way as the first time ,made sure everything was buttened up...and went to start her and nada. I'm running MHD e40 full bolton's. So I checked the codes and that's what i keep getting. i removed The DME...and tested the mosfets and found #2 bad. But would that cause it to not want to fire up? I've looked and looked and I haven't found anyone with those 2 faults!! Help! lol
