200TDI Crank, No Start - Investigation Thread

Whilst I’m waiting for the charger to do its job this morning, I was matching up my fuel pipe routing compared to the video.

I’ve drawn up a diagram which shows the flow.

My fuel is starting into the lift pump rather than into the filter which doesn’t match, and I haven’t (yet) worked out how or if fuel actually returns to the tank or if it just returns to the filter.

Anything look fundamentally screwed here? 😂


Might be useful for understanding the system.

From memory green and brown is for the reverse switch on the back of the gearbox (assuming LT77). So it is not essential for getting or keeping the engine running. Although that doesn’t mean it shouldn’t be repaired!
