Re: Westerbeke - no start post inj. pump rebuild.
If you are getting fuel leakage or spray when loosening the pipe fitting the pump may be OK? Should get quite a bit if you loosen it a turn or two. Perhaps the injectors were set at too high a pressure rating and will not pass the fuel, or enough of it? Easy enough to take them back to the shop for checking. If it runs on WD-40 the compression is probably serviceable. You could put soap bubbles around the injector connections to see if there is air leakage around the connections, but that is probably a stretch. Possibly debris got into the lines when disconnected from the pump and is now plugging the injector tips? Probably another stretch. Maybe remove and blow out the lines? Maybe take both the pump and the injectors back to the shop for checking?
