    Hard to start on cold mornings 300 Tdi

    OK guys any views on this?
    glow plugs OK
    battery OK
    starter OK
    fuel as good as you can get from anywhere
    went to LR dealer said was hard to start on cold mornings , had to glow twice. they said no need to glow here ( Alice Springs) as it doesnt get cold enough to warrant doing it. well mine takes at least two glows to start it first thing but after that no problems at all for the rest of the day.
    maybe it's like me just likes warm climates. :? :?:

    Hi
    Does the 300TDI have a heating element inside the injector pump to heat the diesel fuel????,if so could be cactus.Most japper diesels do and it causes hard starting when faulty.

    Does it start straight after the two glows, or do you have to crank it over for a while. Thinking along the lines of fuel leakdown while its sitting overnight.

    The 300s electronic injection ? Might be the temp sender for the computer.

    I'm with Bushie, sounds more like a fuel supply problem.
    I've never had a problem with mine starting at -7*C here, and my Stepfather never had a problem with his 300Tdi 110 there in The Alice. (has a Td5 now)
    Suttons up there are pretty good, maybe book it in to get checked ?

    Helspawn, no bloody electronics on Oz spec 300Tdi's. :wink:

    Just had a thought (yeah, it hurt), I wonder if there is a problem with the fuel cut of solenoid either sticking when energised (either crap or wear) or a crook connection ?
    I've had a problem twice in the 3.5 years I've had mine with corrosion on the spade causing,

    a. intermittant cutting out when running.
    b. sticking me up when trying to start.

    I reckon they may be wrong and it needs plugs. Letting it glow twice makes no differance to anything else in the engine but it makes makes it start, It's the plugs.

    The 300TDi will start quite happily without glow plugs.....

    The main things that tend to cause poor starting is timing or not enough grunt from the battery. My money would be on the latter (unless you've just changed the belt).... Infact, I'd go as far as to say that it would probably be a crap earth that's causing it.

    Just as a test, use a set of jump leads and connect the -ve from the battery to one of the starter motor bolts.

    Mark.

    PS - It's a mechanical fuel pump....

    You're missing one thing... The battery. The act of using the glow plugs is making the battery deliver power. Delivering power causes the battery to heat up. When the battery has warmed up, it becomes capable of delivering power more efficiently.

    It's a little tip from colder climates....

    If it's REALLY cold, you can help the battery crank the engine better by sticking the main beam on for 30 sec before cranking the engine (one of the tips I was taught when in Canada one winter).

    Mark.

    Yep - can confirm, even though currently only checked at 7c in the morning.

    Living in Sydney, cannot see the use of the glow plugs - but will keep the feeder wire for trips to the High Country and manually hit the glow plugs with current for a couple of seconds.
