I have a problem and a number of questions.........
First, the quick overview...........my port engine cranks but won't fire. Has been perfect all season. It is a Horizon 8.1 in my 2003 340 DA. Now, my main panel has both a main switch key and a black toggle switch that must be engaged in order for the engine to be fired up. I'm sure most of you are familiar with this set up. What's happening is when I place both the key and the toggle in the "run" or, in other words, "on" position and try and crank the engine the black toggle trips to "off" and the cranking stops........
My starboard engine runs fine so I did a small experiment. When I placed the key in the on position and then turned on the black toggle to the starboard engine I heard and electrical "engagement". It's faint but definitely audible. It sounds like a fuel pump being primed quickly for just a second. When I did the same experiment with the port engine I hear nothing. My batteries are now charged (and the port engine cranks fine but won't start). It sounds like the engine may not be getting fuel. Therefore I located the fuel pumps which are located above the gas tanks in the engine compartment. I did the same experiment with the key and toggle switch expecting to hear the "priming" sound when I was right infront of the fuel pumps but they're both silent. That sound seems to come from somewhere behind the panel. I removed the panel to try and locate it but I still can't. I thought perhaps it might be a bad toggle but how can I tell? I'm really frustrated because the boats been great all season. I really don't want to end the season like this. Any ideas what the sound is and if the lack of it could mean something specific as to why the port engine won't fire and continually trips the toggle? Help...........
