check engine coding injectors 2 & 5
 

Over the past couple months have replaced all injectors, injector harness FICM, glow plugs, gp harness, the list keeps growing. Check engine light keeps coming on for injector 2 c/b injector 5 c/b and occasionally circuit low for both too, but not every time. Is there something I am missing as to what could be causing this problem??? These were the codes that started all this work and they just won't go away! Any help or suggestion would be much appreciated.
