Disconnect the battery, let it site without power for a few hours, reconnect and see if it starts. This may sound odd, but I had a similar issue with my X3 and this did the trick.

Battery is sufficiently charged, and there's no other symptoms of a weak battery. Just turns over and over, never quite firing well enough to start. Plugged fuel filter? Some other non-code problem?
Nothing like this has happened previously, always started right up as expected. Car has 90000 miles.
