I just bought a 99 E300 turbo diesel with 200k on the odometer. It runs good but has not started like it should from day one, meaning that it would turn over a couple of times before firing up in warm weather. Now that it's cold, it will not start at all. It is acting like it's out of fuel. Can anyone tell me where I could be losing fuel due to cold weather? Or is there something I'm overlooking?
