Will not start in park (sometimes)

[nkswinburne]

Hi my galaxy mk2 2.8 auto has an intermittent problem. it will start fine first time but when I park up to pop in shops or get petrol I turn the key and nothing. Sometimes rocking the gear selector back and forth does the trick sometimes not and after a while will start . It seems to be doing it more often now' does anyone have an idea what it could be? its driving me nuts. Thanks guys

It's probably the starter inhibitor switch on the selector.
Easy fix, it's a grub screw under the selector surround if my memory is working today
Small adjustments at a time
