Default 2008 800 rzr started ran 5 seconds shut down

Yes sir it started ran for about five seconds shut down ,now won't start at all, fires sometimes the first two revolutionseparate of the engine then nothing ,do they foul plugs often or what, the fuel squirt out of the injector line good at the injectors, I put a plug on each wire it has spark,it just seems to roll easy after two revolutions and won't fire.?.? Any ideas?

First thing I'd do is to check fuel pump pressure even if there is fuel going through the injectors.The pump must hold 39 psi with no drop in pressure or the fuel pump could be weak and need to be replaced.

Code 51 does show the injector but bogus codes can show up even if it's a fuel pump problem only.I'dd still check fuel pressure and it's checked with the key on,engine off. You need an adapter in most cases to fit your fuel rail for pressure gauges.See if this section from a manual helps any. ?CHAPTER 3 ELECTRONIC FUEL INJECTION

OK I ordered a fuel test kit from amazon should be the right end I hope,if it stays at 39 lbs what is the next Step? Oh by the way I went outside a minute ago and rolled it over and it fired up for 5 seconds then shut off an now when it cranks it sounds like there is no compression ??.

Compression should be between 130-150 psi on average on both cylinders.

Well the engine has new pistons rings and jug but I will check the compression just to make sure it's OK it ran fine before it died at the shed.

5/8" or 16mm socket. Either will work. Plus you need and extension,preferably a wobbly. Easier to just reach through the right side opening for both plugs..
