I just took in a 2001 Cavavelle with a 5.7 Chevy FI motor that starts up and runs fine and when you get it out on the water the Injection unit quits pulsing fuel, I have no book on this engine so I just thought I would ask if anyone had this same prob and mabye where to look. Have hot battery and good spark if you add fuel she will run so i suspect FI system or computer???
