Craig, I believe that starter no-disengage issue was on vans equipped with the refrigerator relay under the driver's seat. I believe it was Dennis Haynes or Mark Drillock who schooled me on the solution, although this happened to my manual transmission van. It was as simple as moving a ground on that relay, although I forget the details. It did solve that issue though. Good call on the grounds. A bad transmission to chassis ground will definitely prevent the starter from engaging. As far as that automatic transmission neutral safety switch, I need to check that out. I have an auto, but have never had any trouble with it.
