On electronic fuel injection pumping an pumping an pumping the gas pedal does nothing without the engine running ! Pushing the gas pedal to the floor will cause the PCM - engine computer to go into clear flood mode .

You have some very interesting ideas here , but not really how it works or is !

The vehicle will go into closed loop fuel control when the engine coolant temp reaches a definded temp an the O2 sensor get hot.

She would run for a couple minutes and die which is open loop when running, closed loop is when the sensors kick and it would die. Pulled spark plugs, they were black meaning no spark. Can only be 2

Black spark plugs indecate a rich condition , over fueled , wet spark plugs indecate no spark .

It drops when it is turned off through the return the pump might be getting weak If you keep using the starting fluid you will blow the intake off of it or it will get hooked on it and won't start without it.

It sounds like a bad fuel pump.

Try replacing the throttle position sensor. I had the same problem in my truck. It would start and run for a bit but as soon as you let off of the pedal, it would die. Try it and see if it works.
