Ok, wait a minute.
You say the pump is running? Then the RCM and relay are fine.
You say the pump is getting hot? Sounds like the pump itself is not right, it's airway is clogged (the additional load on the motor would cause it to get hot).
If the pump is running, forget about the damn RCM, the pump itself is bad/clogged/stuck/etc.
And the P401 code is no bid deal, anyway. It just means your cats don't heat up as fast and your emissions are SLIGHTLY higher for a bit until the cats heat up. No big deal. I do'nt like to drive a car with the light on, but it's not the end of the world or anything.
