My 1994 Four Winns 5.8 EFI starts hard when warm. Smells gassy when cranking and wont quite light off. If I go wide open on the throttle, it generally fires right up - ala clear engine mode in a fuel injected Chevy. Suspecting one or more injectors are leaking. I know I can pull them all and get them cleaned (and maybe I should do just that if I have one out) but anyone have a trick to finding out which one(s) it could be? Thought about pulling plugs and looking or smelling for vapors but some of you may know the spark plugs are not the easiest to access in this engine. Other than that anyone have other ideas? Pressure regulator is another possibility, I know.
