Hi my name is***** will be glad to help. That fault means your ECM is not communicating either from a loss of power/ground or a faulty ECM. Check all your fuses and for an inline fuse between the battery box and ECM. Also a loss of engine speed signal to the ECM will not allow the injectors to fire.
