Can someone lead me in the right direction on how to figure out why my 2003 745li wont start?All it does is turn over but wont start. I check the fuel pump by taking the line off and trying to start it to see if fuel pumps out and it did! I'm loss and don't know where to go from here. I tried to start car so much it went dead on me the other day, now I believe it isn't the starter because I can see the belts etc turning when I do try to start it. PLEASE HELP!!!!!!
