I agree 100% with Bob on this - I get worried if I don't "see" oil in (2) 30-second cranking cycles, and go looking for what I did wrong. No oil pressure on the gauge in (4) cycles? I've got a gauge problem, or haven't purged the line.
I's be seriously worried about my starter's and battery's health after much more than that.
