Since I bought my teryx brand new in 2009 it has always had a little bit of a rough start when its cold, but within the past couple days the cold start has been near impossible to start. Yesterday it took me 20 minutes to get it started, with starter fluid and not giving up untill it started. But this morning it wouldnt start no matter what I did, can someone help me out? Is it the spark plugs or maybe the fuel pump or fuel filter. Let me know what you think.
