Try this, open the front wiring compartment...the one below the driver's seat. Look on the INSIDE of this door. Monaco lists any and all hidden fuses on that sticker. Many are inside the door panels under the cup holders. My guess is one of the connecting fuses is blown or one of the wires has come loose from the changeout you had done when the pump was replaced. Most pumps don't have their own fuses unless it was put in aftermarket.
If you still can't find anything, an alternative would be to 'jumper' the pump to make sure it works. Using a meter, (hopefully your friend is still nearby) locate another good 12V source near the pump. Tap into this source and run it directly to the hot side of the pump. See if it runs. If not, then run a separate wire from the ground side of the pump to a known good ground with the new wire still attached. See if this allows the pump to run. If neither of these 'fixes' work, your pump has failed and needs to be replaced....let us know how you make out. I'll monitor this post.....Dennis
