Intermittent spark 2003 rancher 350 ES 4 x 4 my rancher will crank and crank with no spark but every 20 or so cranks. As the weather has gotten colder it gets harder to start, I know it is getting fuel, because it gets so badly flooded. I have physically held the spark plug wire and have even gotten shot every once in a while. I have changed out the plug wire assembly and still no change. What I don’t understand is how it can spark here and there, normally when it’s warmer I can cranking cranking it will eventually go, now it is so intermittent and is too flooded by the time it sparks that it will not start.Please help!
