hellow could some one help me with this one ? my Ram is a 1999
and i,ve got 3 codes that appear at once code p0234 turbocharger overboost
+p0251 fuel quantity solinoide +p0252 injection pump fuel metering control A

Would someone know more where to look i know that my feed pump
is wasted but what are the chances ( % ) that my injection pump is wasted too ?
could it be some resistances in the fuel pumpe cumputer located over the fuel
pump assambley?
is there a code that says that the fuel injection pump is 100% dead ?
