Hi all,
So on 5 seperate occasions now when trying to cold start I have to pop the bonnet and prime the beast to get it going.
It appears to only happen when I park on a slight incline or decline.
Having never owned a diesel before, is this normal?

No not normal from my take on things When was fuel filter last changed?
Check fuel lines as well , but its 08 whats the history??
The Nissan dealer I bought it off apparently changed the fuel filter when they did their bog standard oil change and air filter change before flogging the car. But I have my suspicions to whether it was actually done as the air filter wasn’t.
Since then though I have had it down to my regular mechanic and got the 100000k service done and got him to have a good look over it, he said it was fine but would probably need to go at the next service.
I find it bizarre that the fuel is flowing back and it needs to be primed. As far as I can tell there is not excessive unexplainable use of diesel either.
Hey Beni, I have been having that issue for months now mate...............spoke to a bloke from RAC the other week and he said that it could be caused by the seal on the fuel filter thingy not sealing and suggested putting some grease on it and cable tying a latex disposable glove around it.
I have not tried yet, but will give it ago this weekend.
Thanks Dogman, I have done a bit of research and although it doesnt seem like a common problem, but some people have been suffering from it. It looks like it may be caused by an air leak somewhere in the fuel line / delivery system. It doesnt have to be big leak either.
People are suggesting first and foremost before taking your car back to the mechanic to replace all the factory clamps with quality worm drive ones and double check all fuel lines.
There is also a seal that can wear on the injector pump that can also cause the problem which perishes due to the crap low sulfur diesel we have in the country.
I am going to have a play this weekend as well and will post up any findings.
After doing a small inspection last night I have discoved that 2 of the fuel line clamps even though they are tight are not sealing the two lines that come out of the top of the fuel filter and head down towards the fuel rail. You can easily twist the fule line with your hand.
These are still the stock Nissan ones that look like two bits of tie wire with a Phillip bolt head to tighten them. Several others in that area have been replaced with worm drive ones.
First thing Saturday I am going to replace the stock ones with quality worm drive ones.
Replace those useless clamps. Same was on mine and when I primed the filter after changing it fuel squirted out of there like blood from a cut artery. Put decent stainless worm drive clamps on and is all good. This is what I first though maybe your issue too. Possible air leak and the fuel draining back.
that should nail the issue, sounded simple enough, always good when its a cheap as repairQuote:

Its looking pretty good at the moment, replaced all the clamps and put in brand new fuel lines as well as some were close to perishing.
Will keep yas posted if it still gives me any greif..
So it appears that this problem has reared its head again even with changing out the clamps and brand new hoses, along with the rough idle just after start that I mentioned in this thread;

Its becoming frustrating but I believe that the two problems may be related.
The fuel filter was changed at the last service I had done which was in July but I have read a few threads on the forums about people making sure you always go with a genuine filter over a aftermarket one. I think the one in there now is a Ryco, I need to check.
Do you guys think changing back to a genuine filter would fix the problem? Im stuck for answers on this.

Had this problem with my 07 CRD DX and was extremely frustrating. Much hair pulling and teeth gnashing! Changing clamps etc.
I do my own servicing and the solution was simple - don't use generic, non Nissan fuel filters - changed to genuine item and problem solved - too easy. Was using Westfilter fuel filters successfully for 12 months until priming problem reared its head.

Awesome thanks Les, going to get one on order. Had the beast in bits yesterday installing the duel batt system and checked the fuel filter which was changed at the last service, low and behold its a Ryco.
I just changed to a ryco fuel filter from Super Cheap no dramas at all, very happy, 04 Di
Be interested to see if it fixes your problem, keep us imformed please
Will do mate, ordered from Nizzbits the other day, will report back once fitted.
Have changed out the offending filter for a genuine one, took it for a good run yesterday and all seems to be well with the world so far. Appears to get better mileage when keeping an eye on the Scanguage and the more power when smashing the loud pedal. Will report if this has been a success or failure!!
So far so good!! We are heading up to Shark Bay and Kalbarri end of Jan which will be a nice decent run so will wait until then before giving the all clear.
seems to be mainly crd,s like the genuine filters
