Murano engine cutting out

[Leet]

Hi, has anyone had this problem.  When I first start my Murano, weather it is hot outside or freezing cold its always the same.  The car will start then cut out after a few seconds, it does this anywhere up to 5 times and then its absolutely fine for the rest of the drive. I have had the fuel filter and the glow plugs replaced and had pdf treatment put in the tank. I have run the car at 3500 revs for 10 miles, but none of these things have sorted the problem.

Possibly some air in the fuel filter .... if it has a priming rubber bulb then this should be firm at all times, if it needs pumping up then you have air trapped in there.
