Need more info about the truck. Is it programmed is it Chipped? What mods are done to the truck.
1211 and 1316 are normal codes if you have a chip or programming done to the truck.
P1211 Injector control pressure above or below desired
P1316 Injector drive module codes detected
1211 will have the pcm throw 1316 as well.
