Following up: Power circuit is good, and the relay is good. Apparently there is no trigger signal getting to the relay. If I ground it, relay and motor kick in. Sadly, no idea where to go from here, but....the trigger wire is blue white and so is one of the wires on the solenoid valve. That can't be a coincidence, but....Running, after about fifteen seconds, the solenoid valve kicks in because I can hear the exhaust pulse start up in the hose to the blower. Wonder if both the solenoid and relay are grounded by the same lead or pin at the ECU.
