John:

If you turn the key "on" and do not get dash lights,
fuel pump run, etc, look at your battery, ignition
switch, etc.

If you do get normal behavior at "on" but nothing
at "start", then look at your starter.  No 'click'
back there probably means a gummy solenoid.  Archives
have lots on that.  I know---my syncro won't do
anything below ~20 and from 20-35 there is a delay
while the solenoid pushes through the muck to start--
1-2 seconds.
