Re: 2001 5.3 starting issues
Try checking at the coils themselves. Spark is pcm controlled, so either its not being commanded (tuning issues, coil driver issue, other code preventing spark), or there is an intermittent issue with the wire or coil (or the wiring to said coil).
Also curious as nsb29 said, is it three attempts, or three revolutions?
