1999 SeaDoo GTX RFI, having this exact same issue, (starts with front plug out, but not when in) ordered new fuel injectors, fuel rail, and fuel pump complete assembly, the injectors i pulled out looked really bad, thinking the front injector wasn't working properly which is why i ordered 2 new ones, when i pull the front plug out, it starts and runs good (on one cylinder) when i put it back in, it wont start... did i do the right thing by ordering these items?
