Was warming up and just died. It starts if I spray srarting fluid in the intake and fuel pressure is ok.
Ive got a good meter and am very familiar with electronic repairs and diagnostics,I just am lackingg a manual/wiring diagram. Was also looking for someone else who has had thi happen and maybe some suggestions on whereto look first. Thanks for any help!!

Its a 2018 900 trail. Ive checked the fuses under the drivers seat...all good. Also inspected the grounds that are under the drivers side wheel well in the back and all seem secure. Without a manual Im a little lost on where all the ground terms are that I should check.

KOEO (key on eng off) does the fuel pump prime??? noise? pressure??
