1st: I will bet that 90+% of people that drive a vehicle (any FI vehicle, price irregardless) just jump in them and go. I usually sit for a second and let the oil pressure gauge come up to operating pressure and then go. My wife just jumps in and turns the key. $50 says most people are like her. Most cars made today have one of two things, an oil light or a gauge. Most of the gauges are either on or off type gauges, i.e. a light that looks like a gauge. My blazer has a real oil pressure gauge, but I wonder how many people don't even realize that their oil gauge is no better than an idiot light. Of course, I drive so many diesels that half the time when I'm in my truck I turn the key forward for 10 seconds to let the glow plugs warm up before starting. In my gasoline powered truck. Yeah, I know, right? So, what do I know.
2nd: Start here, read to the end, and then come back and discuss. It's an awesome read if you're into this kind of stuff. I enjoyed it.

3rd: I usually turn the choke on enough to keep it running, then once it will stay running without the choke I turn the enricher lever off and go back inside to kiss my wife goodbye and check the kids one more time then get on my way. With SiSF's kits, it's pretty easy to tell right away if you haven't let it warm up long enough.
