DOES someone has the full procedures to start correctly the two engines of the wilco boeing 777-200
sometime i can start them but the two generators eng still stay off
EICAS message "GEN OFF ENG L+R"
so i cannot start the gps the mcp and also the atc doesn't work so the last solution is to fly with only the apu generator , not cool !

I don't have the plane, so this is just a guess...

MANUAL START:

APU... ON.
(possible 1 minute warmup period before bleed air turns on, just wait till AVAIL lights up on APU bleed switch, then turn it on)
APU BLEED... ON.
PNEUMATIC ISOLATION VALVES... OPEN.
PACKS... OFF.
ANTI-ICE... OFF.
ENGINE BLEED... ON.
FUEL CUTOFF SWITCH... CUTOFF.
FUEL PUMPS... ON.
ENGINE IGNITION.... IGN, START, or CONT (in that order of preferance).
START VALVE ENGINE TWO... ON AND HOLD.
When N1 / N2 stop increasing (max motor), then FUEL CUTOFF SWITCH.... RUN.
START VALVE ENGINE ONE... ON AND HOLD.
When N1 / N2 stop increasing (max motor), then FUEL CUTOFF SWITCH.... RUN.
L GEN...ON.
R GEN...ON.
PACKS...ON.
APU...OFF.
APU BLEED...OFF.

OR...

AUTOSTART:

APU... ON.
(possible 1 minute warmup period before bleed air turns on, just wait till AVAIL lights up on APU bleed switch, then turn it on)
APU BLEED... ON.
PNEUMATIC ISOLATION VALVES... OPEN.
PACKS... OFF.
ANTI-ICE... OFF.
ENGINE BLEED... ON.
FUEL CUTOFF SWITCH... RUN.
FUEL PUMPS... ON.
ENGINE IGNITION.... IGN, START, or CONT (in that order of preferance).
AUTOSTART SWITCH ENGINE 2.... GO.
(once engine 2 started...)
AUTOSTART SWITCH ENGINE 1... GO.
(once both engines started)
L GEN...ON.
R GEN...ON.
PACKS...ON.
APU...OFF.
APU BLEED...OFF.

I'll try and help with other issues once you can start engines properly. Either one of the above should probably work - but everything there is just off the top of my head and from the MD-80 / 747...

Any failures? Also, make sure any DRIVE DISC switches are OFF... and also look in options for the plane, and RESET generator drives....
