I need to know can my ecm be erased to blank and rewritten back to factory. Mine is acting crazy. It is doing strange things with injector duration and timing. It is the only thing left that has not checked out. Injector ok, cp3 ok, fass150 lift pump ok, pop of valve ok,oil ok no fuel in it. Oil filter cut open no metal. :{
