    td5 slow to start cold

    gday everyone, My 04 td5 discovery is slow to start when its a frosty morning ie less than 2 degrees.It will take a bit to fire and then will only run at 400 rpm for around 30 seconds.Then the rpm will return to normal and its fine.Only happens when its very cold. Same problem last winter then fine all year till the cold mornings.Checked all the usual things filters, oil in loom etc all ok. Any ideas?

    Was up your way on the weekend...

    Could possibly be the intank pump, as cold (non alpine) diesel can be a little heavier to push through and build up pressure if the pump isn't well. Around about 100,000km old I would be concerned about the overall health of the fuel pump. It isn't the pump itself that fails/ wears, it is mostly the electric motor that drives it. Of the ones that I have pulled apart, 1 had a melted plastic brush holder, and the other a dead short that kept blowing the fuse. the pump part of the unit was probably still OK

    thanks justin, that makes sense.Since it doesnt sound like a common problem/fix i might leave it till it gets worse as there are no other problems at all.Car has just clocked up 60k.should maybe carry a spare pump.Thanks again for the advice
