Engine will start and run. Then you shut it off and it will not start? Have replaced both pumps, checked all air and fuel pressures, new ECU, changed all rubber internal diaphragms, replaced alternator diode, replaced intake gasket by reeds, checked battery, changed fuel in boat tanks with new fuel with octane boost. When it does run it doesn’t idle smoothly? Can’t think of anything we haven’t done?
