Cold Start Problem LJ70 2.4TD

[Yorkshire Devil]

I'm having a problem starting my LJ70 engine first thing in a morning(with 2.4TD 2L-T engine)

It just seems to turn over for ages & ages since the weather went cold. I can hear the glow plug relay
sound when warmed and suspect the glow plugs might need changing but the car bump starts ok, and will start on the key throught the day, but the manual prime pump doesnt pump rock hard anymore, its looking more like a fuel air problem.

Has anyone had these symptons before, what was the cause? I intend to look over all the pipe work tomorrow but really dont know what I'm looking for or where, any pointers?


Can the pick up fuel diesel pipe in the tank cause this kind of problem?

You can only test the glowplugs,change the primer and yes the top of the fuel pick up is infamous for going rusty and leaking.
As soon as you wobble that fuel pick up ,the leaking will probably get a whole lot worse and you wont be going anywhere.(if its rusted).
So ,you need to know where you can lay your hands on another one .
Im not sure how you are using the primer ,but they shouldnt be pumping rock hard if you have one end of the fuel supply open.
They only have a small rubber seal and not having one end open to allow fuel and air to move damages the seal

I would check for air leaks 1st,its the most likely culprit

Cold Starting Problems LJ20 2.4TD

Started first time this morning on the turn of the key guess the plugs were shot to sh!t. The new plugs seems to make all the difference
