An interesting development...went back out and checked the pump some more to verify that it did indeed have power through all the connections and everything is fine except for not running. Out out frustration I hit it with a wrench and darned if it didn't start running. At least now we have heat and I've only had to hit it one more time.
Still, it's hard to have confidence in the pump so I'm going to order a new one Monday and just stay put in Deer Park, WA for a few more days until I can get it installed. The Weather going E through Montana is looking real bad this coming week so staying here may be a good choice anyway. Snow is forecast through a pass going S. on 15 and I don't have chains for the MH.
Once we get home, I think I can rebuild the old pump and keep it for a spare.
