no spark
 

I HAVE A 02' 450ESP IT STOP RUNNING, IT SPINS OVER REAL GOOD.
I CHECKED FOR SPARK AND THERE WAS NOTHING, SO I STARTED CHECKING
WIRING AND THE CONTROL BOX WASN'T SENDING ANY VOLTAGE TO THE
COIL. SO I ORDERED A CDI BOX AND IT HAD A NICE BLUE SPARK. I DROVED
IT AROUND FOR A WHILE THEN WENT INTO THE HOUSE FOR A BIT. I CAME BACK
OUT AND IT DIDN'T START. I CHECKED FOR SPARK AGAIN NO SPARK.
I STARTED CHECKING WIRES AGAIN, AND WHILE I WAS GOING UP/DN WITH THE
SHIFT BUTTONS I GOT A SPARK, IT STARTED, I TURNED IT OFF AND TRIED IT
AGAIN AND NO SPARK AGAIN. WELL ANYWAY I CHANGED THE NEUTRAL/REVERSE
SWITCH AND STILL NO SPARK. THERE IS NOT CODES BLINKING ON EITHER THE
NEU LIGHT OR REV LIGHT COULD ANYBODY HELPED ME OUT. DEER HUNTING
SEASON IS COMING UP. THANKS
