Well, I just started using a Miner on SSP and I just got lava in my way. The Pump doesn't remove the lava, though I have empty cells in the pump and it's right next to the Miner, on the other side of the miner is the generator. Chest is right next to the pump and a seperate chest for the miner. Could someone help me?
Tried powering both the miner and the pump?

Yes, they are both powered. I have a RE-Battery in the pump, I know the pump works with the RE-battery because I used for lava but the lava has to be right underneath it....is there a problem?
Whenever I've set it up, I do it like this:
[Generator]
[cable][cable]
[miner][pump]
[chest][chest]
Empty cells in the top slot of the pump. You didn't accidentally put empty batteries in there? 
Have you tried removing the drill and putting it back in? Miners seem to permanently stall when they can't continue and need to be manually reset before they will try again.
I'm having this same issue. The pump simply fills with water but won't output a filled cell. If I move the same pump to above an actual block of water it works correctly, simply not when placed next to a miner.
Edit: Actually, I just inspected the mine-shaft and there was no water. Even with the mining drill removed and mining pipe retracted it still seems to pump water from somewhere. But there is no water.

That happened to me, too. The pump draws water from nothing when attached to a miner. Also it doesn't fill the empty cells put in the upper slot of the pump and I can't even place empty buckets in the top slot. And yes, it was all wired.
I am using IC² v1.90 with Minecraft 1.2.4 by the way. Would be nice to hear an official statement if this is a bug. 
I've noticed that, but need to look into it. If I can't I'll ask Al.
I did a search on the forum (gasp) and found this thread, having the exact same problem while using Technic. While reading the thread, however, my pump actually popped out a water cell, even though it looks exactly the same as the image above. It would seem the pump is working properly, even though the pumping animation isn't.
I'm having this same issue, it's just not putting out any water/lava, it's frustrating. The miner also won't retract.
