Thanks for the info, on how to test it. The symptoms I am haivng are a no crank, when in park, but if I wiggle the shifter in nuetral, or move it, it starts. Then some times it doesnt. Battery fully charged, gas tank full of fuel. Those are the reasons why I suspect the NSS, instead of some other sensor.
