My pump is short cycling on just one zone, no leaks in valve box

My pump is short cycling on just one zone. There are only three heads in the zone and they will come on for about a minute but kinda pulsate and dont run at maximun spray. Then they'll go down and then come up again for about a minutes and so on.

There was leaking in the valve box but I tightened everything and no water is coming out but the short cycling continues. I don't see any pools of water indicating a leak, so I'm stuck.
