I'm having a strange problem with the -200.  When I start the engines using APU bleed air the packs go off,  the engines start fine, and the hydraulics and electrical systems power-up as expected.  The problem is that there is no bleed air from the engines.  The two bleed air switches stay lit.  Eventually the packs come back on but if I look at the "Air" status display I can see that they are being powered by the APU rather than the engines.  The display shows no green path from the engines.  If I turn off the APU, the packs go off and the duct pressure drops to zero.  Also, the engines do not respond to the throttles.  If I move the throttles the engine display shows that they have moved but power does not increase. I have all failures disabled.  Any ideas?

 

Thanks

Can you please post a screenshot of your overhead panel and EICAS 'AIR' page, just before you set your first FUEL CUTOFF switch to RUN? Also post the same screenshot as soon as the EICAS is no longer showing 'APU COOLDOWN'.
