If you did not get the hoses mixed up (color coded as you know) the next thing I would check are the rod actuators down on the cable ends of the joy stick. These are outside, underneath the right hand side of the frame, just trace the cables coming from the joy stick. See if the rods that feed into the actuators for fluid flow are free from friction and hooked up properly. They can get rather stiff so some synthetic lube or light grease will help them slide. This also gives you confirmation that they are working while moving the joy stick while standing on the ground and looking at the cable ends. Check your FEL manual too, there might be help there.
