P1294 Code. Injector connections are good, and have tried different FICM. Checked all wiring associated with ficm and ecm. Tried another ecm. Injectors resistance all measure ok. Truck has a new engine and compression is good. Truck idles with a lope but not fuel pressure related. Truck runs perfect when accelerating and loaded. Injectors 1,2 and 7 Always have different pulse at idle than the rest. Can injectors cause this code even if the resistance is ok? Anyone run into this and find a fix?
