[Gmecm] Cold start problem

[Bill - Comcast]

You win Darryl.  It was the crank position sensor.  Stop by and pick up 
your free beer any time. :-)

I don't understand why it gave so much trouble when cold and worked fine 
when warm,  but it's much better now with a new sensor.  The old one was 
apparently contacting the crank flag and was warn down.

Thanks for all the replies, guys.
