Hi! I’ve got Lots of whitesmoke constant. Unburnt fuel, no doubt. I see railpressure jumps between 25 and 60Mpa, when IPR/FCA is disconnected it jumps to 138mpa so I don’t think it is pump. FICM is changed, running fuel straight from can. The injector balance is in the pictures. I am thinking about changing injector 8, and maybe FCA. 1 is ok normally (around 1) but injector 8 always lay around 5-6 mm^3. Is there anything else I should try before changing injector?
