I have a 1998 Four Winns Horizon 180 with a 4.3GL Volvo Penta. Took it out on the lake a couple weeks ago and it quit running after it sat for an hour while the kids were swimming. Got it back to camp. Wasn't getting fuel. Next morning it started right up. Took it out this weekend. Started right up. Ran for an hour or so. Parked at beach so kids could swim. Got in it and started right up. Went 50 yards and died. No fuel again. The fuel pump is not coming on. Got a new relay and the fuel pump will still not run. I checked with my volt meter and when cranking the plug at the fuel pump is getting between 10-12 volts. Does this mean that my fuel pump is bad ? Never had any issues till this yr when it sat over winter and now this yr, this fuel problem. Thanks Pete
