Sorry to hear that it's still not working. One last thing to try before swapping EZKs is to unplug the EZK and measure the CPS resistance at the EZK connector (engine off key off). Looking at the EZK connector with the cable on the left, the top row left-to-right is pins 1-13, and the bottom row l-to-r is 14-25. Pin 10 goes to CPS-1 VR-, pin 23 to CPS-2 VR+, pin 11 to CPS-3 shield. From your earlier measurements, resistance across pins 10 and 23 should be ~175ohms. If you then unplug the CPS, resistance across EZK pins 10 and 23 should be no connection even on 1Meg ohm scale.
