what will cause a 400 sport too get very lil spark?will not start at all. tried new plug still very lil spark.

 

Bermbanger400 I had a simler problem on my 99 trailblazer. I was out riding one day and hit a water hole and it quit running. I tried everything to get it running but it wouldn,t. Here it turned out to be the wire under the hood that controls the kill switch had water in it and wouldn't let it get enough spark. Because mine was just like yours i had very little spark not enough to make it run though. Try this and see if it works. Let me know if you need to know witch color of wire to check and i will go out and look to see what color mine is tomorrow. Hope this helps.
