Robert,
I was starting to go through all this complicated measurement stuff
and replacing switches and all when my van wouldn't start. It turned
out that the red wire connecting to the starter had a loose
connection. Since you just did some work in this area with the
transmission, it might be worth looking at . . . Way easier to take a
pair of needlenose pliers and tighten that connector than to go
replacing switches and taking measurements all over . . . Cheap too!
:^)
