No reprogramming needed, it relies upon the pressure sensor to bring it into play and to cut out when the pressure is held in the system. Something is not holding the pressure in the block.
 
Hang on, there has been two pumps both behaving the same?
Is it something in the brake valve block? There must be some kind of NVR in there?
If both pumps do the same thing possibly the block is at fault?
Yes. It was stopping just fine then one day my son drove it and said breaks went to floor to stop. Then I bought a pressure switch and changed it, same issue. Then I bought another abs pump with an accumulator and pressure switch. Before removing the original abs pump I just switched the accumulator, same issue. I then swapped the original abs pump and accumulator with the purchased abs pump and accumulator, same issue. Which is why I was trying to get an answer to this,
I am curious no one has answered this question, does the changing the abs pump ever require an analyzer/be reprogrammed to bleed air out of the system?

I have heard stories of the brake pedal going to the floor when a plastic part in the modulator breaks. A guy in Australia used to make stainless steel replacements but I am not convinced it is a design flaw, more bad luck. I took a modulator apart and it wasn't easy. Better just get one off the Bay.

Just so I'm following the block and modulator are the same correct?

The modulator is the square thing under the reservoir bolted to the bulkhead which the brake pedal is connected to and the brake pipes come out of.
