I am having trouble starting my 1993 525i. A couple of weeks ago I noticed that my car was having a little difficulty starting. After going away for the holiday for a week, I came back to find that it won't start at all.The car was running fine up until this point. Now when I turn the key it cranks and cranks but it doesn't sound like I am getting any spark. If this sounds like something you are familiar with, could you throw me a bone? I don't want to have to haul this in and pay $100/hr to some guy if it's something I can take care of myself.
