NHK: Temperatures rising in spent fuel pool #4 in spite of water injection
http://www3.nhk.or.jp/daily/english/25_12.html

The operator of the troubled Fukushima Daiichi nuclear power plant is carefully monitoring the situation at the Number 4 spent fuel pool, where the water temperature is rising despite increased injections of cooling water.

Tokyo Electric Power Company, or TEPCO, says it will inject 210 tons of water into the pool on Monday, after finding on Sunday evening that the temperature in the pool had risen to 81 degrees Celsius.

The utility firm had earlier limited the amount of water being injected into the pool to 70 tons a day, saying the weight of the water could weaken the reactor building, which was already damaged in last month's hydrogen explosion.

On Friday, TEPCO found that the pool's temperature had reached 91 degrees, so it began injecting 2 to 3 times the amount of water. more at link

4. More than just injecting water..
They need the water to circulate, and after the damage, you can probably safely assume some fuel assemblies were damaged, which means loose pellets in the pool, so Boron would be a good thing to inject as well as getting the water circulation and heat exchangers up.
