My 2014 2 seater reeperwith the 812 c.f. cherry motor will not start. Ran it all day. Parked had dinner. Went to start it and it started then immediately sputtered out. Hasn't started since. It's got Spark, fuel,and even tried starting fluid to bypass bad injectors or low fuel pressure. Checked it has compression, the timing marked are lined up perfect. No valves are sticking. I've pulled the positive cable off to reset the computer multiple times and grounded the lead against the ground. This issue is over my pay grade I guess. Please help.

Rule of thumb, if it has spark, and its in time,and it has fuel it has to run. did you try spraying starting fluid into the intake where the rubber air box hose connects? is the air intake restricted...ie is it getting air? is the fuel line at the pump hard to press together? did you check any fuses? just a few things. maybe someone else has had the same problem search wont start or something like that. let us know if you find the problem.

I've done the starting fluid,it sputtered just a little bit just once after using about half of a can on it. timing marks are lined up. Valves are opening and closing.its got good spark on all 3 plugs fuses all look good. I think the computer may be regarding timing for some reason that is the only thing I can think of. So I've unhooked the battery to reset the computer going to leave it unhooked for 24 hours to see if that will reset it
Are you checking the spark by pulling the wire? Have you actually checked spark across the plugs? I am assuming you are pulling the rubber hose at the intake to spray in the starting fluid.
There are a couple things that may effect the ECU and the signal it sends. You didn't say if you had any run issues before this problem.
When checking again you can pull the O2 sensor connector on the exhaust and disconnect. Also unplug the MAFS sensor on the intake. See if it will start and run with these unhooked. If so reinstall one at a time to see effect. If either of these help you may have a bad ECU. Also check all wiring as it runs to the ECU. By my own experience I have had a wire get scraped by the metal holding tabs. Although it created a no spark situation.
This is an odd condition as it has all it needs to run as others said. You may also unhook the ECU connector and reinstall looking for signs of corrosion on the connector.
If you were having any run quality issues prior to this happening it may help to state what they were to help with the background of your issue.

I would also check the continuity of the cheap O kill switch as well. Mine made a good game of "Toss For Trash" for the kids to play. Its been several days now have you started to check any of its problems?
