Hi guys,
Since I heard about the starting issue on this car before buying it I always thought it was a fuel pressure issue but after getting planet on it I found a glow plug relay fault and with the starting issue worse when it was cold in the mornings I thought I'd change it to see if that sorts it.
Changing it didn't solve the problem but I did a video of the fuel rail pressure, I've noticed that it's not very high and I'm thinking this is why it's not starting well.
There are no signs of any diesel leaks on the high pressure side so I can only guess the pump, injectors or both are worn out but could the HPR cause low pressure in the rail? I'm not getting any cutting out issues just the slow to starting problem.
Heres the video I made.

This other video is of my girlfriends 206 2.0 HDI starting. You can see it builds pressure so quickly that it starts before you can see the numbers for the pressure rising.

Also because I can see the injection quantities via planet does this mean that I don't need to do a leak off test on the injectors or is it best to do one anyway? You can see in the first video that injector 3 is injecting a lot more than the rest, could this mean that one is the dodgy one?
I look forward to your input.
*EDIT
So you don't have to trawl through the thread the issue was the injectors. Swapped them out and it now starts first turn of the crank.
