First, you better make sure (don't be offended) that the pump and valve are installed in the right direction. Many of us have put a new valve in and somehow gotten it in backwards. I suppose it could happen with a pump too. Then, check to see if the switches on the valves are in the right position. But, it certainly sounds like you didn't have prime in the pump to start with. Cruising at 15 MPH or so should put on plenty enough pressure to prime the pump. Once pumping you can park while it fills. Good luck! Also, if you get the pump working and the valves still aren't right you can get new ones at Home Depot for about $13 each or for about double that you can get the Irritrol 700 series ones that many of us rave about.
