halfers:
Any one had this and found the cause of it ?.Truck will be starting on the key and running fine one day and you come back to it the next morning it will fire up run for about 10/20 seconds then cut out. You try turn it back on and it will just crank forever with no luck. However we have figured that if you pump the manual primer it will fire straight back into life and not have the problem again for a few days…
No set pattern that we can see yet it just seems to be random and no fault codes shown either. Once we have primed and started again it won’t be an issue for a day or two…

I am not a Renualt tech ,but DAF If you can get it to prime with the hand primer ,it may be your low pressure pump may be at fault and can not supply the pressure required …Make sure there isn’t a blockage in the system ie filter on the pick up pipe in the tank …But if anything like a DAF low pressure pump sounds faulty
