I can't figure out how both fuel pumps don't come on and no waring buzzers or chimes .. but the starters work .. Any Ideas ? Im lost

How about some more info, like what motors? Kill switch maybe

wow . Kill switch makes a lot of sense . I will check . My kid was playing in the boat when i was replacing the port Mech fuel pump . ( not to be confused with the electric pumps ) ..They're 575 sci's

I remember him asking me about that switch too .. i told him how it worked . He must have tested the Lanier . It has to be it . Thank you

Also , i have had problem with the port side engine starting ... With the new mechanical pump . It popped rights off . I think there was diaphragm bleed through going on
