Phillip, when this happens. Can you turn the car off and release the fuel cap and re-intall it and let me know if it clears up for a few days?
OK. I will try this. I presume you just mean open and close the cap where I put in the diesel?
I should also have said in my original email that I believe the fuel consumption has increased dramatically. As in my Pathfinder appears to be much thirstier since this problem started. Maybe it was a bit better when I got the new fuel filter.
Thanks a million Jane.
FYI, I no nothing about engines so consider me a complete beginner.
Exactly Phil, I see these symptoms alot on the pathfinders and frontiers with the same engines.
Usually the result of the suction control valve on the pump, which works like a throttle to supply fuel volume to the high pressure pump. When they start acting up you can usually release the pressure at the fuel cap and it temporarily rectifies the problem. Just a little trick an owner can try without going into to much technical diagnostics.
I mentioned I had a couple of weeks with no issues but the problem came back again last Saturday.
Thereason I mention this is that it came back after I filled the fuel tank completely with Diesel. The problem kicked in about 5 minutes into my journey after this fill.
What do you think is the long term solution to this problem?
For now I will open the fuel cap before and after journeys - if I can remember to do so.
Are we done?
I understand I need to open and close the fuel tank cap when it happens again. I am wondering if I should leave the cap loose so air can get in?
Is this a good way to progress or should I just get a new Suction Control Valve?
Can you supply me with a SCV?
Sound man Jake.
Is there a part code or will I just look for a Suction Control Valve for a pathfinder. How long should it take my mechanise to replace. Is it easy to access?
I'll rate your service now. I am a first time user and very impressed. Thanks for all your help.
I had this part replaced as you suggested.
I find that the fuel consumption has increased dramatically.
Is there anything I can do to get better fuel efficiency?
Is the Suction Control Valve the same at the Fuel Pressure Sender?
Hope you can help.

Yes. the stalling problem is gone , unless I stay in Neutral. If I am in neutral it can return. I would not say it is stalling just no power to go forward.
Is the Suction Control Valve the same at the Fuel Pressure Sender? I went to the Nissan dealer in Cork for the SCV part you suggest but I think they game me a Fuel Pressure Sender. I have asked them to confirm but they cannot find my order on their system.
The part was fitted by an independent mechanic in early May when we were last in touch. I will ask him now if he recalibrated it.
I am not very mechanically minded so sorry if I come across a bit stupid!
I will follow up and let you know.
Yeah - he said he recalibrated it so I am going to have to bring it back to him and see if he did everything properly.
