Re: Yanmar 1GM10 won't start.
+1 on rethinking your theory about it not being fuel. There are 2 bleed points on my 3GM. The one on the injector pump is not obvious. Ether is really bad for these little diesels, so the less you use it the better. You also need to be careful of hydrolock from cranking too much. Any miniscule air leak from fuel tank to injector will cause it to not start.
