<snip> came to the conclusion that it is the park/neutral switch. <snip>

<snip> The Bentley is absolute crap in regards to troubleshooting this
switch. Is anybody out there with experience on it? <snip>

On my '84 GL, I lifted the carpet enough to remove the screws holding
down the shifter cover.  I was then able to access the contacts for the
starter lockout (or enable ... depending on how you look at it) and I
cleaned them.  Works great now.
