Repairs 2008 eXmark lazer z 60"---28hp Kohler Command EFI will not start

I have a 08 eXmark from new and never had an issue with it till now, when turning key on for about 5 sec. till fuel pump stops buzzing it should start right up. But when turning key the red code light flashes instead of buzzing, you can still hear the fuel pump kick in but the red light is intermittent and will not start ?? any suggestions ?? Thanks

I'm guessing this is a fuel injected mower? You need to read the codes off of that red light.
