Landing gear will not retract

[Rickskymaster]

Went flying this afternoon, retracted gear and the doors would open but the gear would not retract.
Put gear handle down and the doors would retract.
Tried it several more times with the same result.
We change out the gear pump last annual with a new one.
Any ideas would be welcomed.
I have searched the site to see if anyone else has had this problem and could not find.
Need assistance asap.
Thanks
Rick
