Starting problems

["Jordan Morris <deloreanjordan@xxxx>" <deloreanjordan@xxxx>]

Hi all, 

I went to start my D today and yet again it wouldn't start. The 
engine turned over a couple of times then stopped. The battery gauge 
reads less than 8 but everything electrical works, even the cooling 
fans???? I'm sure it's not the battery because it's just had a new 
one and the problem only seems to have started since it's got cold. 
I've read something about the cold start valve but didn't really 
understand it. Is there any way to stop this happening for good?

Thanks, 

J
