Recently my Envoy's been taking a bit longer than normal to turn over from a cold start. 3 solid seconds is the most it's taken so far and it once took over 2sec after driving a couple miles, stopping for 5 minutes, and starting it again. The autostart feature (short key flick) won't crank the engine long enough to cold start the car which leads me to believe that it's out-of-spec. Is this indicative of a problem that could bite me later?
I've tried holding the key at "on" for 20 seconds before starting to build up fuel pressure. That didn't help. I also turned the accessory pulleys by hand while doing the CPAS last weekend and all turned smoothly.
Potentially relevant recent maintenance: (trans/xfer case etc. omitted)

There's ~105k mi on the odometer.
