Does anyone have any experience with a 2040? I cannot get it to start, I am getting fuel to the injector pump but nothing out of it to the injectors. I have removed the end of the pump (where the fuel comes in) and cleaned everything in there including the filter. When I turn over the engine with the end of the pump off I can see the assembly rotating like an old rotary engine but have no idea how to go into the pump and further. Any advice would be welcome at this point as i am at a total loss what to try next. Thanks.
