I had a similar prob with mine at the start and air was getting in the system from the leak off rails.
Also check your lift pump. Fuel may be draining back overnight and thus a !Expletive Deleted! to start. Replace if necessary.

Well, it is a new battery, well last year anyway, and a decent one at that!
I thought that a direct injection would fire quick too......
Leak off rails? Lift pump? It's all electronic on this model, fly by wire and all that!!

--- Quote from: "muddyjames" ---My disco used to be exactly the same and wouldnot start when a small amount of frost had come over night and then as soon as I get the jump leads out and put it next to the disco it started 1st time!
I spent 2 hours changing the glow plugs and even now after the light goes out on a really cold morning the engine turns over a couple of times and then fires up.
I am thinking about getting a new battery and see what happens. How old is your battery? Batteries do loose their efficiency over time and escpecially in cold weather.
I am guessing with regards to fuel waxing as somebody mentioned if you were to have a full tank of diesel it would take longer to wax over?

Mine seemed fine with jump leads when I flattened it trying to start it! First turn it was away, only after about 5 seconds of the jump leads being on!!
With new plugs, it still turns over a fair bit before starting even when no frost. Though you can leave it all day at work from 7 till 3.30 and it starts a treat - chug chug brooom!!
Just first thing in the morning it is reluctant.......
I thought for the fuel to wax it had to be like minus 15 or suchlike at least, and modern fuels had a anti waxing agent?????

Mine had a new lift pump replaced before I bought it and it was done under a year ago. I have the reciept for it!

Yes but still has both of those ; the pump gets the diesel to the engine from the tank and the leak offs are the return for unused fuel. (I think) :roll:

I suppose it's a dumb question but air can get in and cause a problem via teh leak off rail? I believe the banjo connections for this are prone to coming loose - certainly I checked mine and they were really not quite tight enough and a friend had one fall off!
