Re: Yanmar 2gm2f no start after fueling

I can turn off the fuel valve (at the tank) in my boat and my 2GM20 will run for a few minutes, so I doubt that it's a clog anywhere very far upstream of the high pressure pump. Make sure the pick-up pump hasn't lost its prime for some reason (i.e., bleed the system). If the pick-up pump seems to be getting fuel, then the problem must be in the high pressure pump or the injectors.
