160sr wont start in hot weather

[Fatcarp22]

Bought a cheeky lil 160sr off a dodgy dealer. Problems with starting car happened on second day of owning. Will not start on a hot day.
Turn key and all dash lights come on as per usual but turn key again to start & get nothing. Leave doors open for half an hour to cool down inside of car n bang. She starts.

Dealer doesnt want to know and cba with hastle of writing letters to trading standards etc, so down to me to fix otherwise im micra less.Any 1 had similar problems ? Im guessing its a common fault on k12s & im not alone.

Thanks for reading guys n gals.
