ser number 2BOO9989. 2013 250 pro xs. I have Removed plugs and tested compression.. plugs oily and wet. turned key on with kill switch hot and hear fuel pump cycle. No pressure on starboard rail schrader valve. I know it could be a myriad of things but what should I check next? It tries to start and stumbles and dies. It started one trip before it quit altogether. It started rough on that trip initially and no problems. Rough start on this trip..tournament, and stumbled and started after first stop and then nada at second stop. Good compression. I understand what the different pumps do, pulse, LPFP, and HPFP, but don't know what to diagnose first. Any help appreciated. FWIW, I have a motor sitting on a stand with #5 cylinder bad but all parts sitting there fully assembled so its easy enough to pull and replace parts. Just want to know where to start.
