Tues. night the sled ran great, broke the shocks and rear suspention bracket. fixed them. Went out last night and it went about fifteen miles and died. It has spark, kind of faint. we took the fuel rail off and it seems to be pushing gas. when we did this the box was flashing two long red lights and then three short flashes. No other flashes after we reassembled the fuel rail. I'm lost. spark, air, and gas normally results in fire. and it has compression. Ive read about the batterry problems. we just replaced it a few weeks ago. could it be bad already? Has anyone had this problem??? and can you help me out??
