Accomplish the ENGINE FAILURE/SHUTDOWN checklist.
If temperature is in the yellow band:
AUTOTHROTTLE (if engaged) . . . . . . . . . . . . .DISENGAGE
[Allows thrust lever to remain where manually positioned.]

Move engine start lever to IDLE detent at a minimum of
15% N2.
If EGT does not increase in 30 seconds or another abort
start condition as listed in normal procedures occurs:
ENGINE START LEVER . . . . . . . . . . . . . . . . . . . . . . CUTOFF

Engines may accelerate to idle very slowly, especially at
high altitudes. Slow acceleration may be incorrectly
interpreted as a hung start or an engine malfunction. If N2 is
steadily increasing, and EGT remains within limits, the start
is progressing normally.
