Electrical question

[Greg930]

My auxiliary air valve and warm up regulator are powered through pin 87 fuel pump relay 2, have continuity from 87 to plug going into regulator. I put a jumper from pin 30 to 87, but no power to regulator. Checked for a short hot wire in to regulator and a groung point, showed that the hot wire was grounded. Traced back through plugs and engine compartment fuse plate, and back to the plug going to the fuel pump. There was the red and green supply wire going to pump, and the red and white wire both connected, going to air regulator. checked for a short, hot wire going in to pump, and grounded the other test lead, absolutly no resistance. So my question is, if electricity, like water takes the course of least resistance, how would the power get to regulator, the power would go through pump to ground. Am I missing something? Tested + to - on fuel pump no resistance, is that correct or is the pump shorted?
