Default Long start times, any ideas?

Just got my Jeep back on the road after a year+ swap effort. Runs great, plenty of power and whatnot. My only issue is it takes a long time to start. Fuel pressure is good, and does not drop down after the pump does its 2 second prime. I haven't really dug into it yet, but anyone have any ideas of what might cause a 5.3 to take 5 seconds or so of cranking to start?

Thanks,

The cam sensor would be the first thing to look at since you know the fuel pressure is good. No cam sensor signal will add a lot of cranking time before the engine starts.

You know, now that you mention it, I bet I disconnected it when I was trying to remove the oil pressure sensor. Thanks for the heads up.

Thanks again for the insight, I had indeed unplugged the cam sensor and forgot about it. Starts right up now!
