Re: Yanmar 2gm20f

The engine did not run on time of purchase. We did start only on WD40 not on the fuel was in the tank. I guess was an old fuel inside, that's why I did replaced it.
The both pressure levelers are in closed position. When I opened the #2 the engine stopes, same like when I loosed the fuel supply to the injector #2, the engine stopped again but not when I was playing with #1 pressure leveler and injector fuel supply.
I did not use any command from the helm, all operations were made on the engine block, the throttle end shutoff valve.
When the fuel supply tube was removed from high pressure pump to the injector #1, wasn't clogged,and after cranking the engine without putting the tube back, no fuel was coming from the high pressure pump.
Is it any chance to have fuel pressure for second but not for the first injector?
And is it any connection between throttle and shutoff not working with fuel supply on the first injector?
