I'm not a diesel engine expert at all and I'm having an issue with getting the engine started since the last time the boat was out last week. It was working fine until we were returning to the dock and, after reducing throttle, it died (fortunately we had enough momentum to coast the rest of the way). When starting, the gear is in neutral and the throttle is in the middle somewhere. I have tried giving it a little more throttle when starting to see if that makes a difference but that hasn't changed the result. I have also closed the raw water intake to hopefully not fill up the exhaust with water. Here is what it sounds like:
Based on the information I have found so far, it seemed likely that this was a fuel problem so I started looking for a manual pump to bleed the system. As it turns out, this engine seems to have an electric fuel pump and when I turn the key for the ignition into the 'on' position, I can hear the electric fuel pump making a sort of clicking sound. Will the electric fuel pump stop when the system is sufficiently primed or will it continue just keep running as long as the ignition is set to 'on'? Is it possible to 'over prime' the engine? I left the key in the 'on' position for at least 5-10 minutes. It is possible I did not let the electric fuel pump run long enough?
To bleed air that might be in the fuel line, I loosened a screw on the top of the fuel filter that is mounted on the engine while the electric fuel pump was running. After I got a steady stream of diesel, I tightened it. From that fuel filter, the fuel lines seem to run to 2 locations on the engine. Are these the correct places to unscrew to bleed the fuel? (see images named 'steps removed looking closer' 1 and 2) I tried unscrewing the first one but it just seemed like I was stripping the screw. Would a wrench work better? On the right side of the 'steps removed access' photo, you can see the fuel filter on which I was able to unscrew the bleed screw. In the bottom left of the 'port aft berth access' photo, you can see the orange fuel filter which leads to the electric fuel pump (mounted on the left (port) side of the engine) and then it leads to the fuel filter that is mounted on the engine. Would it be worth trying to get these fuel filters apart to see if anything is going on in there? Do I need to fill them with diesel when I put them back together?
Any ideas are appreciated. Thanks!
