First thing i suspect,and teat,on these is the in tank fuel pump.When you, key on engine off,the pump relay will trigger and run for ten seconds,1st test,can you hear it ?
2nd test is for flow volume,it has to flow at least 140 ml of fuel in the ten second relay run,so uncouple the fuel line that goes into the filter and put it in a jug,one you can measure the output,KOEO less than 140mil and the pumps shot,the actual flow rate is 80-100 litres an hour ,less than 140 in ten seconds means not even 80 L/h.oh and pump output isn't measured by the ECU so there is no fault code.
After these tests and if it passes then you need the kind of diagnostic equipment that doesn't relay on computers,gauges for pressure and return and injection test equipment so local diesel specialist is the order.
And just to chear you up I have one in right now with a full march of your symptoms and this one has had everything changed/renewed,turbo,pressure sensor,injectors...........etc ,the lot,I ran test 1 and 2 it failed test 3 is to hook up a slave fuel feed and return from a gallon can using a 12 V pump it started and reved to red line and thats as far as I got that day as now the tank has to come off for a new pump and I have to find rom for 20 gallons of fuel first.
