    Have you attempted any type of diagnostic scan?

    Do you have a Check Engine Light on? It could be a number of things from the crank sensor to a dead fuel pump.

    That should have nothing to do with your no-start issue.
    A scan for BMW codes is needed to reveal why the CEL is on.

    You need to do some basic testing:

    Check for sparks by removing a coil-over-plug unit, fitting a spare plug in it, reconnect the loom and rest the plug on a metal surface of the engine
    Get someone to crank the engine - do you get sparks?

    I'll have to try that in the morning. Really a coil out and try to turn in over ?

    Yes, the suggestion from Timm is really a very simple way to verify spark.
    Follow whatever testing procedure Timm recommends, he knows these vehicles very well.
    He is a resident expert here, if you haven't figured that out by now.
    Visit his website using the link, you will be amazed!
