My question is will the heater door and actuators function if the ECM does not receive the signal that the engine is running? I'm using a stand alone ECM so the car thinks it's turned off, and with the A/C pump gone it can't make cold air. The heater coil is circulating as the coil always does, but I get nothing but cold air from the vents regardless of settings.

Neither the engine nor A/C compressor running would have any effect on your heater functions. Except, of course, if the engine is not running your heater core will get no hot coolant, thus no heat. But that's not your case, since your engine is actually running. So, it made me think of a common issue with these cars, and that's the deteriorating foam on the heater baffles. Do you know for a fact that you had heat BEFORE the engine swap?
If not, this may be your issue:
