I have a HPDI 200hp, 2000 year model Yamaha blowing the fuse to the ecu/fuelpump. I have disconnected the fuel pump along with all sensors going to the ecu. As soon as I turn on the key the ECU/fuel pump fuse blows. I have used a test harness to eleminate the remote harness as well. The only way it doesnt blow the fuse is to disconnect the ECU harness prior to turning on the key. Before I spend 1500 bucks on this ECU I wanted to see if there are any other test I can do?
