I have replaced the cam sensor, checked the wires top is batt voltage middle is aprox 5 volts and bottom is ground replaced the ecm and still the car dies after 5 seconds and will restart right away but dies again some terminals on ecm plugs were corroded with a green goo tried to clean plgs with wd 40 and starting fluid but still have the same problem the code it sets is cam sensor feedback circuit out of range. What am imissing or what else could it be
