08 Navara Cutting Off

[Amanoo]

Good day,
I have an '08 D40 Navara YD25
On initial startup the van idles and cuts out after a few seconds of idling and tumbles alot when restarting unless I prime the primer pump then it tumbles less to start back up. Once the van is restarted the vehicles runs fine until it is switched off for a period of time. I already changed the fuel filters, the primer pump and serviced the SCV. What could be the issue?
Thanks for any assistance that can be rendered.

Most likely culprit is a fuel leak. Finding it is easy and you have already used the tool needed.

Prime the system - it should take 4 to 5 squeezes to become firm. Now continue priming for another 10-15 squeezes. You should see diesel leaking from somewhere. Find the leak, fix, problem solved.

It might be a good idea to try this test on someone else's lawn because diesel will kill the grass.
