apparent damage.
If X–START is shown:

[Allows electrical power to starter.]
FUEL CONTROL switch. . . . . . . . . . . . . . . . . . . . . . . . RUN
If an abort start condition as listed in normal procedures
occurs:
FUEL CONTROL switch. . . . . . . . . . . . . . . . . . . CUTOFF

Engine may accelerate to idle very slowly, especially at high
altitudes. The time from fuel control switch to RUN to
stabilized idle may be as long as two and a half minutes.
Slow acceleration may be incorrectly interpreted as a hung
start or engine malfunction. If N2 is steadily increasing and
EGT remains within limits, the start is progressing normally.
If engine starts and runs normally:
GND PROX FLAP OVRD. . . . . . . . . . . . . . . . . . . . . . . . .OFF
