I have had the same problem for a few years on my 1997 Pajero (160km - I've had it from new). Only occurs during cold weather, no problems at all in summer. Problem can be overcome by pumping the primer on the fuel filter for a few minutes until motor has warmed up. I replaced all the rubber fuel lines between filter and diesel pump and fuel tank. This made a big improvement but not cured. I have been told it is the seal in the diesel pump (expensive to fix), but I don't understand why it only occurs for such a short time during the cold weather so have been putting off doing this. Motor runs perfectly in all other respects
Cold start and cut out after short run
i replaced my fuel pump seal car has not cut out since but still has cold start problem in that it runs lumpy for a short period untill warmed up other than that it runs fine been all over the uk in it without a flicker
i never had lumpy start problems during warmer weather
suggest check fuel lines from tank forward to fuel pump
cold start lumpy idle only as weather has gone colder
had cut out once but has not cut out since new fuel pump seal fitted but still ran lumpy just at start up.
very cold morning and snow now it wont start
fitted new ngk plugs still wont start
got to fit none return valve, inline fuel filter, clear fuel pipe to see fuel and any air bubbles also to clean and check EGR valve and check and replace the glow plug relay as i suspect it aint getting power to plugs or not enough also need to get cold start device on side of fuel pump checked one statement a guy posted says his started ok when moved this manually
i know i also have to replace the fuel pipes in the sender drill out and replace with stainless steel ones use baulk head fittings to go through tank.
ps batterys had over 12v and turned over no problem.
to sum it up i suspect in order:
glow plug relay or bad connections (modify if faulty with hot start switch)
cold start valve device on side of fuel pump (but i have no info as yet on these)
ERG valve needs cleaning or blanking off?
fuel pipes drawing in air from a rusty pipe or bad connection?
