C7 Starting
When starting my C7, the starter always cranks for approx 2 seconds before the engine starts. My C5 always started in a micro second. Is this normal for the direct injection engine.

Actually, darn it, I might be wrong W88! Am I inverting how it works? You need the oil to be a certain temp before VVT works, i think I'm conflating pressure and temp.. Nothing Google can't straighten out for me..

Now that I think about it I remember when I had my '01 Grand Prix GTP, on cold winter days, I would have to turn the key to the on position and wait for a second or two until I heard the fuel pump cycle otherwise I would have one hell of a time starting the car. I'm guessing that's what is happening here except it does it automatically. But I'm an IT guy so I could be totally wrong.

Wouldn't be surprised if the oil needs to be warm for VVT but I don't claim to know much about it. Perhaps they want the engine to be warmed up before playing with cam timing for emissions sake. Would be interesting for a subject matter expert to chime in. Don
