Probably not connected, but sometimes when I start the car it doesn’t run for more than a second. Then I start it again and it’s fine. Seems to drive ok - no obvious change.

Thank you
These engines are new to me so excuse my lack of knowledge. Is this accessible? I would have thought it near the top of the engine but it’s clean up there. |

Thanks for the pictures- much appreciated. Given leak seems to be lower down I think the last one is most likely. And it could be the starting issue is linked. I will have a good hunt around - probably have to be next weekend now.
Thanks for the info. |

That’s really useful thanks
Where is the pump physically located - is that on the n/s of the engine? |

I’ve had a good search around. Top of the engine is clean - it seems to coming from the bottom/side of the fuel pump. It is difficult to see exactly where due to access. I can’t really see much from the bottom of the vehicle and the top is obscured by all of the pipe work.
It won’t start at all now which I assume is due to the lack of fuel pressure. After trying to start there is a small puddle of diesel on the floor so it’s coming out at a fair rate. Any more tips before I submit to the professionals? Thanks |

As its your fuel pump leaking only thing i can think of fuel line connectors and VCV valve

I don’t think it’s the VCV - you can see that quite easily from above - right?
It is quite a bit lower down - either bottom of pump, which you can’t see, or something lower. Is there anything lower that could leak fuel? |

Not sure if connected but in the summer the fuel rail pressure relief valve was changed. Possibly the suction control valve was also changed. I wonder if my issues relate to that?
