Hi everyone, Looking for some advice. I have a 04 sportsman 700 EFI. I have replaced the ecu and now the fuel pump turns on when I turn the key and the inline filter fills, yet I am not getting any fuel to the cylinders. I poured a little down the spark plug holes and it started. I have checked the codes and I get 51 and 52 (injector 1 & 2 error). How do I test my injectors? Or is it something else? Any advice would be appreciated!
