Hi,
This is my first post so apologies if a I ramble on a bit.
I have been getting this error message Loose Connection for quite a few weeks now, it only happens maybe once a week, and only on start up i usually leave for half an hour and it then starts fine. This Morning however it did it again but was followed by a message Water In Fuel Filter, now it will not start at all. I dont really know much about this or how to even get it started so i can get it to the garage. Any help would be appreciated.

Thanks & Happy New Year

Sorry forgot to mention it is a 2004 Fiat Stilo 1.9 JTD.

What happens when you try to start it?
Does the engine turn over but not start?
Does it just click?
Does nothing happen at all?
How old is your battery?
