G'day all,
Just wondering if anyone out there has had experience with having their Patrol Fuel pump replaced? I'm waiting for advice from Nissan Dealer if this is the next step in fixing my Patrol that is running pretty poorly...advice today after primer pump and filter replaced is pump temp is at 95.5%, way outside normal operating temp of 50-70%. Nissan Service scratching their heads, have asked head office for advice!! They said too early to tell if worst case scenario, which would be new Fuel Pump? I understand that this can be a costly exercise, has anyone got any advice as to what sort of $$ this would normally cost, or if there is a more economical "Non-genuine Nissan" alternative? Any advice greatly appreciated. Thanks all.

Had
mine done about 3 months ago, if you have comprehensive insurance they should cover it, get it removed and stripped by a reputable pump specialist, if there is wear in it no matter how small get the repairer to do a repair report and put it down to dirty fuel, even if it is the electrical side of the pump, claim engine damage due to dirty fuel.
Mine cost $5300.00 including labour to R & R. I only paid the excess.

What exactly are the symptoms,as there could be a number of causes being a 3.0,they are a very complex system.

G'day Matt,
Initially, engine malfunction light came on very intermittently. Fuel consumption got progressively worse, performance lacking quite considerably - now have to give it 1800-2000rpm just to move it off the line otherwise it stalls. Engine malfunction light now on all the time. Primer pump and fuel filter just replaced by Nissan today due to their diagnostics telling them of some error which they tracked down to air in the fuel system. made no difference to the performance - engine light still on. They have sought advice from their head office - some mumblings about fuel pump hence my initial enquiry I posted regarding fuel pumps.
Cheers

Ok, i work for a fuel injection company and see many of these pumps (VP44). I see a lot of them removed for no reason and quite a few that have failed.I would be making sure they have exhausted all fault code avenues before committing to have the pump done, It is a BIG job to R&R the pump and can be very costly.Just remember that your pump CAN be tested before you commit to have it exchanged or o/hauled.The PSG or pump controllers do give trouble from time to time.
Good luck with it.

Matt,
I was under the impression that the pumps for the 3.0lTD can't be overhauled. Is this true? What sort of $$$ is it for an overhaul if possible? You also mention that you have seen many that have failed. Is there a common fault?
thanks......Leroy

Flyboy,
You will find quite a lot in archives about Nissan fuel pumps, cost for one 2 mths ago was $4,500.00 so I hope you don't have to go down this path. Mates first GU had all the signs of a faulty fuel pump and it turned out to be the air mass sensor

Can any of you explain to me please how/why the pump temp is expressed in % and not degrees in this post.
Also if it is % then % of what.
By that I mean what does 'pump temp is at 95.5%' mean.
95.5% of 6 or 2009 or 100 something or others.

Agree with Mathew C.
Make sure they check ALL fault codes.
Do you have a non original air filter?
A dirty Mass Air Flow Sensor will give the same symptoms.
If you can, take it to a reputable diesel specialist.

There is a lot of COMMON faults with these engines/pumps, it will normally be the electronic control box or a problem with the internal advance.Yes they can be overhauled or repaired,like i said there is other cost options other than new genuine replacement.
Air mass meters cause huge problems in these cars,if your air cleaner is dirty or if an aftermarket one has not caught all the dust then the dust lodges on the sensor inside the air mass meter and gives a false signal to ecu causing low boost/high boost and fueling issues leading to angine failure in many cases.
As 3.0turbob said take it to a reputable diesel mechanic,also the airmass meter will not always give a fault code.
