I bought a used 2000 Ultra Custom boat Model J454S-CAL 454 7.4L engine. I replaced the usual; spark plugs, oil, oil and gas filters, new starter, new Grp 31 battery, fresh gasoline. When I crank the engine it turns but wont start. I add a very small amount of gas into the carburetor and the engine starts right up. The engine stays running without any other problems. I can run the boat on the lake but after I turn the engine off the only way to restart is to add the small amount of fuel into the carburetor again. I'm thinking of replacing the fuel pump but I'm wondering if there could be another cause and/or if there's a way to verify that it is or isn't a fuel pump problem? I'm stumped.
The Marine Power manual shows the fuel pump as #0303-06F1 Electric 7.5 PSI. I'm finding all sorts of information on what could replace the original fuel pump. I could also use help with any suggestions. I'd like to get as close to the original specifications as possible if the pump does need replacing. Thank you.
