Before putting the kite in the hangar we do a check of the boost pump bypass valves on a ground run. This involves both engines started, all pumps then turned off, monitor EGT, n1,n2 and FUEL FLOW, steadily wind her up to static t/o power whilst ensuring no popping/banging/coughing etc and ensuring the fuel flow is steady and equal for both engines. Left at static t/o for a couple of mins to monitor fuel consumption and if all is satis, throttle back and monitor fuel flows and watch out for signs of a flame-out.
I've done loads of these and have never seen an aircraft where the engines struggle to get fuel or flame out.
