2001 GMC Sierra 1500 SL 4.8L Hard start
This one has a hard start (long crank) after sitting while hot it fires right up when cold or right after it's been shut off...but if it sits for a while it has a hard start... I was going toward a regulator leaking but I see no sign of leakage and it still do...
