Fuel

[bobbby]

Hi all
I have a JD 445 tractor the fuel pump is pumping fuel but the injector is not spraying.The injector was replaced last year so i wouldn't think that would be bad again so soon.Any thoughts would be appreciated.
Thanks
Bobby

Not a lot of details , but IF the components are all good, usually the system is air bound. Have you tried cracking the nut on the injector to bleed out air. Also, check the lines to the pump for air leaks, allowing air to enter the fuel system.make sure the fuel filter is sealed good , ( pinched oring etc) I have seen bad primer pumps cause fits too
