Lots of News! Sorry for the late response guys, a lot has happened with this fiasco so far.
So it turns out that the reason I was getting a "No response code" was because I was trying to use the obd2 port under the steering column, when I should have been using the circular connection underneath the hood (mine is an early 2001 5 Spd)
I have now replaced both the wheels speed sensor and had the module repaired. My speedometer now functions 100% of the time.The company said my unit was bad and successfully repaired it. I believe this as my original issues were fixed.
Now for the bad, I went to clear all the codes but now I have a new issue :-( I am now getting a code "(35) 53 Inlet Valve Front Right". It is my understanding that the wires going to these valves are very fragile and easy to tear or break the solder during installation. Can anyone shed any light on this situation? Is this valve (sensor? solonoid?) on the HCU or on the ABS Module I just had repaired. As you can imagine the three lights are still on my dash.
Thanks again!
