I am having troubles with engine start after installing the patch. I have not seen anyone else with this problem. All other aircraft are fine, but the 747. I have APU Bleed air on (APU Started of course), fuel configured, Autostart on, Pack 2&3 off, and when I pull the ignition switches the engine do not spool at all. I get a reading that the ignition is active but no spooling of the engines. I have started this airplane 100's of times before the patch and I'm not sure what I'm doing wrong. Has anyone else experienced this?Thanks,Troy StevensUAL6210http://virtual.united.comhttp://www.precisionmanuals.com/images/forum/supporter.jpg

Troy,Cutoff switches to IDLE?Hope it helps,

Mats,Yes the cutoff switches are at idle. It's really acting like there is no Bleed Air from the APU. Im stumped on this one.Troy StevensUAL6210http://virtual.united.comhttp://www.precisionmanuals.com/images/forum/supporter.jpg

How about the L/R ISLN valves?
