    Default Diesel Pajero cold starting issue

    Hi all
    Recently, I purchased 1992 model Pajero diesel 2.5TD. Im facing the problem of cold start. In the morning, it refuses to start even after 10 heaters. After 12 o clock noon, it starts after 2nd or 3rd try. And after starting once, then without any heater, it is half self start. Also gives smoke at start.
    It is driven more than 300k kms. I want to know from experts whether it is due to glow plugs, timing, valve seals, or nozzles of pump.
    I know the problem will be resolved after this cold weather but want to dig out the reason. Also suggest any other solution if needed.
    Shall be grateful for this help.
    Regards

I am having peace of mind al hamd o lillah as I dont believe on local mechanics and their skills and they cheat.

    You are right that 100% personnel effort is required I often read ih8mud.com and whatever I search came up about HJ60 and I have repair manual too, so its better to understand and diagnose the problem by yourself and then get it verified by Toyota mechanics I often print out the relevant page of repair manual to show them as well. They know me very well and my jeep now.

At 3lac km, a mitsubishi diesel has almost certainly lost compression which is why its giving this problem.
    Unless you get it rebuilt, you will be wasting time and money on everything else that you do.
    So please also consider this dimension of your problem.

    Well in my opinion, Engine Rebuilt/Swap will be the last option. First I would try every other method as stated above by experts. Thanx for the suggestion btw.

    Nice link. This type of Relay fault is also mentioned in an international forum. But I forgot the website.

    this is my old E300D - Mercedes Benz installed a block heater in the engine at the factory - All I needed to do is pop off the cover and use an extension cable on this - its a 500W heater that really warms up the block for easy arctic starting (honestly never needed it but did it once or twice in 0~5C just for fun)

    you take an extension cord and plug it in to your house electric socket, the heater has a heating coil exposed to coolant that warms it and keeps the engine warm. When I did it in 0C, the glow light went out in 3 seconds and the engine fired immediately on the first crank - I also had cabin heat immediately.

    I did it for fun - not needed in 0C on mercedes E300D - Its needed at -10C and below along with full synthetic oil.

    Now I got it. I thought, it was a 12V DC heater. 220VAC 500W good. BTW Nice Idea Boss.

    These also show up in scrap, most scrappies think they are some sort of sensor. I have seen this in a lot of Toyota 1KZ and mitsi 4D56 too, they were installed aftermarket and are placed where a regular welch plug (tikli) will go.

    I have a toyota 2C diesel engine and recently went a trip up in the mountains last December, although not very cold but 8 degrees is way below my normal daily temperature, I am glad to say that my engine started at the normal glow timing of 5sec.

    Thanks @Xulfiqar for the tips!

    speaking of this - I once have also done a similar act. It was not a stove though, I got myself some burning red coals and put them in a trough - slipped it under the engine and let it warm the sump with radiant heat.

    Started easily after that.

    I think fire is a bit too risky considering if the engine had an oil leak.

    This was in Pakistan and the stupid hilux was filled with SAE 40 engine oil. I also had to drain the radiator of its "pure water coolant" and fill it up the next day with warm water. - All in all I hated that truck and billed all the work I did as "man hours" to the company

    Well, 2C is easier to start as compared to Mitsu 4D56...I think. Two months ago I sold my 2.0D Corolla which was half self start on a single glow of 5 seconds even in freezing weathers.

    your 4D56 is not upto snuff then. It should also start on first crank.
