Hey guys i have been having a serious problem with my 2007 navara
it smokes really bad first white then black and has also loss power it does not want to move , it also sounds like its starving for diesel .No faults codes are comming up we have checked the fuel pump ,changed the quantity control valve, tried new injectors,new computer, checked the fuel rail pressure the nissan garage is clueless right now .Can anyone share any light on this?
 
Dirty airfilter, dirty maf, replace both the fuel filter and the water separator, check for crossed up vacuumlines to/from vacuumpump and vnt solenoid (the ones that cross over te top op the engine, going to the intake and vnt, shops frequently reattach that bundle of hoses wrong).
 
boost solinod, down side of air box. open air box and rev truck, if you cant hear turbo whistle and the large boost pipe doesnt inflate, then the turbo isnt spooling.
