Remove the console around the shift lever to get at the neutral safety
switch.
to get that cover off, start at a tiny allen screw on the shift 'knob' ...

once the console cover is off ...simple matter of seeing two big fat
wires..( don't confuse back-up light wires with starter wires ) .
just jumpering the two starter wires together will bypass the switch there,
if that's the problem.

( don't tell anyone ...I rigged a manual push button starter button and
put it right above the light switch on the the panel on the left
there...that way ..
in times of very expensive gas....rather than sit at a traffic light
idling  and wasting fuel ..
I can shut off in Drive .... then turn the key back on immediately.
when it's time to go ...just push the button ..she fires right off in
Drive and away ya go.
This is only for those smart enough not to start it in gear unless they
really mean to.
Not recommended for your common ........ah .............your common
person. )

Today though, not even a click from the starter. I've shifted it from part to neutral a million times and tried in both positions. Alas, no luck.
