Cold Start Issues
My 2005 530i will start here in No. Cal. when its over 50 degrees for the most part. when it sits overnight and temperature gets to mid 30's it wont start in the morning. After temperature warms up it starts. I was lead to believe by Elk Grove BMW my fuel pump was operating intermittenly, so i changed the fuel pump. Now the car wont start at all. Is there a chance that a dirty fuel filter could be the cause of this and the intermitten not starting when its cold?
