if the vp44 dies does it aleays set a code? Mine is not pumping ANY fuel when i crack the injector lines open. and i have no codes. thanks for your help.

 

Look at fuses and relays. Can't get a code from unpowered unit. If you have power to ECM and VP44, that pretty well sets the stage for replacement.
Not unsual for no codes, although P01693 generally manages to show it's ugly rear.
