My 2001 Yamaha 150hp Z150TXRZ dash gauge shows the boat tank empty and won't transfer oil. it's full. The emergency engine manual transfer switch works which eliminates the boat tank pump. I have metered the boat tank switch wires at the engine connection and have continuity showing the tank sw is closed & working. I have jumped the engine connector to the ECM to show the tank is full. Same result. This model unfortunately controls this function with the ECM. The ECM is super expensive, am I missing anything? And there seems to be some confusion on which ECM? Something to do with whether the primary coil wires are grey or black, mine are black. The part # seems to be 68F-8591A-01 which I can find salvage for around $4 or 500. Has anyone had this same problem?
