I have an 03 GTX that is very finicky and hard to start. Once it's warmed up it starts well but at cold start it can be a real pain. If you miss it the first try you are screwed and it will not start again. The battery is fully charged and it cranks over like crazy but no go. I replaced the plugs and still nothing. I bought the unit used and the original owner told me to squeeze the throttle fully twice before you turn it over for the first time. This seems to work sometimes but not always. Any help wuld be appreciated cause this machine is driving me nuts.
