I'll chuck in my penniths worth, fit a temp clear plastic line between the filter and pump, if its an air problem you'll see it. Blank off the EGR, even if its not the source of the problem (and could be), the engine will benefit from not having exhaust fed into the intake.

Hi all, can anyone tell me if installing an EGR blanking plate will solve a faulty EGR valve? Nissan want $1800 to replace the valve. A mechanic told me the cause of my v9x running rough was the EGR valve being stuck.

Does anybody know where I can get detailed information on the bosch high pressure fuel pump? Best I've found so far is a rather poor exploded view. I'd like to see how the pump works and if there is any possibility that it can introduce air into the fuel system.

Old Tony, thx for your input. Ive bled the system with the bleeder pump numerous times and still have air coming out of the system, so I doubt it is residual trapped air. I'm leaning toward an air leak on the injector spill and fuel return lines. The v9x motor has a cold start fuel...

Hi all, does anybody have experience with air entering the fuel system on a V9X motor? Problem is between the filter and HP fuel pump. No sign of any fuel leak on the tangle of fuel lines, I pressured up the lines, still no sign of leaks. Put clear plastic pipe on return line from pump to tank...

Alas no, it has a stupid bulb pump that connects above the pump, once bled the bulb pump is removed and the cap replaced. So it sucks the fuel through unlike most systems that have a built in primer pump on the filter. So cant pressure up the suction side of the fuel pump.

Well my woes continue, turns out it was not a fuel delivery problem. I removed the tank and inspected the somewhat over engineered fuel pickup device in the tank, checked the line from filter to tank. Only issue I found was a crushed breather/ balance pipe between the high and low points on...

Thx all, problem may be solved, will know tomorrow. One question, does anybody know if there is a check valve in the fuel supply line from the filter to the tank? The current garage had conceded defeat! I asked them to replace the filter again. Yesterday started and ran fine, parked nose down...

Guys, thx for the input. I doubt there can be much wrong with the engine given the amount of scrutiny it has undergone recently and the fact that when the issue clears or goes away the car runs fine and goes like the clappers. I will definitely look into the DPF aspect, however I thought it'd...

Still no joy, Nissan could find no reason for the problem and the injection garage that currently has the vehicle have also been unable to find any issues. They removed and tested the injectors and they were all found to be good, so they are not the source of the issue (thankfully at a grand a...

Thx guys, its now in the hands of the diesel doctors. Hopefully they can identify the problem. At $1000 a pop (nissan quote!!) I'm hoping it's not the injectors....

Thx for your input, this is proving to be a painful and costly experience! I'll look into the pump idea.

Tony/Adhaul, thx for your input, that's a very useful observation with the bleeder cap. I'll definitely be checking that out. The problem has deteriorated to the vehicle being unsafe to drive, it often misses badly when trying to accelerate. So took to a local injection place and they didn't...

Hi all, anybody know the secret of how to unplug the loom plug on the top of the accelerator pedal? I'm guessing you have to somehow unlock the plug before you can pull it out...
