Hi Bought a bmw 635 csi that had been stood for 2 months it is MOT'd for 10 months. Put a new battery on her, drained old fuel and put fresh in but it will not start. Has great spark on all 6 plugs l, pump working as should, fuel on all 6, dried plugs and put oil in pots to create compression but it will not start. Any ideas will be greatly received Cheers Tim
