I have a 98 gmc searria my fuel pressure was low so i changed fuel filter and fuel pump and its still starving for fuel someone told me map sencer i used the code reader and no codes
Ok, have you checked the fuel pressure regulator? On my vehicles it goes from fuel pump through fuel filter to fuel pressure regulator to injectors. Picture is supposed to be the OEM replacement for the '98 GMC Sierra 5.0l and 5.7L
