Do you get the contact "click" with the engine running and you push the button to engage the 4X4?
I'm still trying to figure out if you are getting vacuum to the cable actuator under the battery.

when i hear the contact this is with the motor off and the car in park

fred, I don't know how you can diagnose it if it doesn't have a 4 wheels off the ground.
I would have it sitting on jackstands, engine running, 4X4 engaged and see if the vacuum actuator is pulling the engagement cable, or at least pull the cable as you have done, but with the engine running, trans in drive and transfer case engaged.

Jack up front end place jack stands underneath. Dissconnect 3 bolt housing, dissconnect shift cable,now MANUALLY pull out on fork shaft. If you spin one tire and other doesn't move shift collar not engaging. Most likely cause is bad thrust washer behind axel gear. Washer kit $10 from dealer. To repair you must remove shaft tube. Hope this helps.
