Hello, I was out running the boat over the weekend and my boat lost power and quit. I took it home running multiple test. Found out the high pressure fuel pump wasn't activating when the turn the motor over. I ended up bench testing the fuel pump and seems to work fine. I then used a multi meter to chk voltage from ecu plug in which I was only getting 11.5v I see that I'm getting spark and power to the injectors. My guess is a faulty ecu? Unless a possible ground issue. Any suggestions or other things to consider is much appreciated. I heard these don't go bad rarly but does happen.. thanks
