i have 98 that wont start. it was running and my cousin was just cruising around and it died, my dad tried to start back up after he pulled it home and he said it would just roll over and backfire some? i went over and work on it and wouldnt start so i put new plug in and no start, pulled plug check for spark on plug and nothing, dont have spark, im thinking coil, but for 135.00 for new with no return, is there any way to test the coil, cdi? stator?the quad has 1500 mile, any help would be great, thanks
