I did all the trouble shooting, added gauges to the pump. Wasn’t building pressure or holding. The bedroom slide would hardly creep out and had to pretty much manually push it back in. Due to fluid bypassing internally in the cylinder.
My kitchen slide was leaking due to rust on the cylinder rod. Ruined the seal.
So I installed new cylinders and problem fixed.
