JLG 450A 3 Functions not working

I have a 2000 model JLG 450A, Early serial number. Anyway, I bought the item recently at auction, and have fixed most of its problems. I still however have three functions that do not work.
-Basket level up and down
-Extension in or out
-Basket pivot. Right or left.
I can activate the function from the basket or the ground and have active coils, but no movement. I can hear the pump slightly labor under load, but no movement. Any ideas.
