I have a 2007 700 Arctic Cat EFI LE 4x4 four wheeler that absolutely refuses to start, it has good compression, it is firing and has a new spark plug. We were driving it, headed towards the trails we ride and half way there just completely died and had to be towed back... When turned on before trying to crank it, the spedometer needle will jump from 0 all the way up and back down to 0, 8 times. Then EFI starts flashing on the spedometer screen. When jumping the plug to show error codes all that shows up is EC 00. Puzzled is an understatement, new to owning an Arctic Cat so someone please help?!?!
