new pump, new thermostat, flushed system ,refilled and bled. Coolant is full, still overheating and heater cold. Heater core? Would that make it overheat?

was heat working before you did all of your work?

get car warm and feel heater core hoses. if they cold or warm suspected restricted hoses, cores or air in line. if they both hot then it is in the air ducting.
