Hey guys ,
I took my boat out for a ride today when suddenly the port engine died and couldn’t be restarted . I cracked open my cool fuel module to check the filter and noticed it was pretty much empty . That lead me to believe my fuel pump wasn’t working . I ran to my local marine supply store and he only had the high pressure fuel pump in stock ( a Hail Mary attempt we were supposed to go on a trip tomorrow ) so threw it on but no dice . I noticed when I cycle the engine on I don’t have the high pitched wine anymore like my starboard motor does . I only hear a low hum of one of the fuel pumps . My mechanic is likely two weeks out . Its def fuel related , not the IAC sensor .

Bad relay somewhere ? Bad fuse ?
anything else I can try ?
Merc 496 8.1 2006
