2014 HyperSP. I changed the oil Friday night. Ran it up to temp and checked for leaks, all good. Shut it down and parked it. Saturday morning wouldn’t start. Still won’t start. It turns over. I’ve verified that I’m getting a spark and it will sometimes back fire. So I know I’ve got spark and gas. Tried a jump pack and a new battery. Checked all electrical connections and fuses, all good. WTH?! Any thoughts? Anybody experience that sudden failure to start?
