Narrative:

At FL340; with autopilot autothrottle on; and left center pump off/cross feed open 700 pounds in center tank we experienced number 2 engine rollback and autothrottles disengage. Recognized engine failure and captain assumed control of aircraft. Declared emergency with center and began drift down descent to FL290. Executed engine fail checklist from QRH. Started APU. Attempted engine in flight start; which failed. Noticed spar valve was not opening and no indication of fuel flow on start attempt. Attempted second start attempt at FL220 with same result. Secured engine per checklist. Notified cabin crew to perform emergency briefing for divert into [a nearby airport]; maintained FL200. Decided nearest suitable airport to be ZZZ based on longer runway; better breaking action report; lower landing weight; better familiarity. Obtained weather and performance numbers from dispatch for [the divert airport]; all within flaps 15 limits. Planned and briefed flaps 15 landing and executed single engine descent checklist. Notified passengers of divert. Executed single engine approach checklist and again obtained current weather and breaking action reports; still within limits. Executed single engine landing checklist for RNAV approach autobrake max. Landed overweight by approximately 1;500 pounds breaking action good. Clear of runway requested exterior inspection from emergency response personnel; who reported no abnormalities. Taxied to gate.
