Hi,
I wonder if someone might be able to help, I have had a Navara D40 (57) completely standard (no chip or fuel changes) for many years now and pretty much ever since I have owned it I have had an ongoing fuel problem with it. It seems to be the standard common issue of P0093 (Mass fuel leak). Over the years I have tried many different things like fuel filter replacements, all being genuine, ecu resets etc but what seems to fix the issue has been the replacement of the SCV however it seems to only last for around 9 months.
Symptoms always start with the occasional going into limp mode, usually while cruising or under very little to no load. This begins maybe once a week and get's more frequent to the point where when it does it it will sometimes stall rather than just limp mode and then struggle to start.
While I don't mind changing the SCV every 9 months I feel like it might be just covering up the problem rather than resolving it.
It started again this week (SCV changed last September) so today I thought I would test the relief valve, it mentioned removing the pipe to it, adding a new piece of pipe and a bottle to see if the valve is opening. What I thought was strange and this might be normal is when I started the vehicle fuel came out of the pipe I had disconnected from the RV in what was a bit of a trickle, I would say maybe in the space of 20 seconds it would be around 100ml. Is this common and expected? As I thought this is the return pipe or does this indicate the valve has been releasing and so the fuel in the pipe was simply from previous runs?
Does anybody have any suggestions or have had similar experiences of replacing the SCV every 9-12 months?
Thank you and much appreciated.
