so the starter motor is turning over then?

Then it is not a security issue - that would prevent the starter from turning over altogether.
A car needs three things to start, fuel, spark and compression. If the car was previously running fine, we can rule out a compression problem.
After ruling out a compression problem, by far the most likely cause of this a failed fuel pump, which is preventing the car from getting fuel. You check the fuse for the fuel pump to be sure, but the pump is a fairly common failure. There is also a fuel pump relay but relay failures are rare, while pump failures are common.
A replacement fuel pump for your vehicle is about $300 plus about 1.5 hours of labor.
The only other possibility would be no spark condition which would be commonly caused by a failed crank sensor. This can be verified at home by spraying quick start starting fluid spray into the intake (if you are comfortable doing so - be careful as this can cause a backfire). If the engine starts on the quick start, then you have verified that there is in fact spark present and the fuel pump or fuel delivery is the problem.
I would say 95% it is the fuel pump that will need to be replaced. This is almost always the case with a crank-no-start condition on a BMW.
