hey guys went 4wding last week end and my mates truck died

he managed to restart it once but ran really rough and smoked quite abit then stalled. since then we havent managed to start it again.
iv checked power to the glow plugs and even pulled them out and checked each one individually. i then cracked off injectors and made sure it was getting fuel but still no luck. what should i check next
its a ln61 2lt surf

So its definitely got fuel? and is it injecting in a sequence when you crack off the injectors?
They will eventually start with glow plugs not working but if not try putting a jumper lead from the positive terminal on the battery and to the glow plug rail for 10 seconds.
Also try draining out any crap from the fuel filter but to be certain replace the fuel filter.
Then make sure its bleed right up, remove the fuel supply to the injector pump from the filter housing at the filter housing side pump hand primer until fuel streams out, refit fuel line. Keep pumping hand primer until it gets hard it should squeak as the relief valve opens.
Try to start. Make sure you've glowed it first. If it starts give it a good rev until it clears up and runs smooth.
If none of this work also check the basics eg no fuel leaks, theres fuel in the tank etc etc
Next step is take it to a mechanic

unbolt the turbo outlet pipe. possibly the turbo has siezed which sometimes can choke it enough that it won't start.
also, not sure on the early ones, if its got a butterfly in the inlet that its opening and if its one of the egr equipped ones block the egr off it could be stuck open.
