I'd try re-potting. The soil might be used or somethings wrong with it.. Watch out for root bugs.

I assume, that you do have a Cereus sp. cactus that is found growing naturally in a country with a tropical climate, i.e. a "jungle cactus".
Those plants do require a growing medium that does have organic matter, will need more water than a "desert cactus", and also would do better with an application of water-soluble fertilizer. If you are interested in flower production, make sure, that the second value of the formula, the phosporus (P) is high. If the plant is in a large enough pot and the growing medium (potting soil, cactus mix, etc.) has recently been replaced, there should be no reason for the plant to look pale and refuse to grow. One thing that can cause a "bleaching" of the stem segments is perhaps too much sunlight. Placing it in a slightly shadier environment would result in the "leaves", i.e. stem segments to return to a darker green color.
However, if you do not supply enough light, the plant will grow spindly and refuse to flower.
