330CI won't start

It is 2004 330CI, E46, odometer is about 130k km.



Engine won't start, but crank.



Mechanic checked fuel pressure, fuel pump, filter etc, all good.



I aslo tried to start with another key, no luck, just crank.



I feel my car is totally dead...



I started my car less than 10 sec and moved a little bit in the garage a few days ago, so I thought the engine was flooded.



I tried to press and hold gas pedal to start many times, no luck, just crank.



Now should I try to replace the spark plug and CVV?



By the way, my car is leaking some kind of oil, I have changed oil filter housing gasket but it didn't work, still leaking and getting worse.



Please save my life....
