X5 e70 won't start after charging battery.

I disconnected the battery to charge over night, and now the car won't starts. (Cranks strong but won't start).

Any ideas? I've changed battery before without issue but taking it out over night send to be different to take it out for a few minutes..

Thanks,
Fred

Dont they have an immobiliser that kicks in after a time. Have you tried locking it , then unlocking it and trying again ?

Yeah maybe I don't know.. I did try lock and unlock a few times but it didn't work.

Battery is definitely charged, the crank is strong..
