I been storing my 190 for six month intervals for about ten years. It's my driver in the winter and I drive my '91 MR2 in the summer, so I swap them back and forth every six months using the above storage prep, and they are stored inside.

Neither has ever failed to start just as if they were sitting overnight. Modern fuel systems are sealed and the pump is energized at least briefly when you turn on the key. At worst if it doesn't start in about four seconds. Wait about thirty seconds and crank again.

Other than doing a basic visual inspection of fluid levels, tires, checking for rodent damage, and ensuring you have a good, fully charged battery, there are no special procedures necessary before you attempt to start.
