Intermitent starting trouble, 850GLT 93, automatic

I´ve being having a comic trouble:
sometimes the starter doesn´t turn at all, being in parking. When I
shift to neutral, sometimes starts, but others I need to hit the
shifter, in Neutral position, and the starter turns very well.

This problem usually happens when the vehicle I use for, aprox., 5 min,
turn off the key, set to park and, up to 15 minutes, try to start again.

 

Hi,¨
I have the same problem in my car, a volvo 242 with 960 b6304fs engine and the
960 automatic transmission aw30-43.
Even though my car is RWD and yours is FWD, the basics for the PNP switch are
the same, I figure.
