2009 x5 4.8li cranks but not starting.

I resently replaced the valve stem seals and valve cover gaskets. The engine cranks but will not run now. I did not remove the heads, there is fire 1at the fuel rail and when I pulled a coil from each bank there is spark. There are no codes showing up. Any ideas besides a dealer?

I had the same problem when doing my valve cover gaskets myself. My problem was that I did not fully clip in the spark plug coils all the way. lol. Check out the coils and harness and let us know
