Went off to work this am, lately the bike have been running a bit rough off idle and has stalled a couple of time. Anyway on my way out, still cold engine, I have a downhill section where I was decelerating throttle off and the bike stalls and I can't start. When I turn the ignition on, I don't hear the fuel pump priming. Is this an r/r issue and what tests should I be doing to pinpoint? Forgot to add, starter does turn over.
