Re: 2002 gmc sierra 3500, 8.1-flashing mil, dies/hard to start

I have an '02 8.1 as well and have had the same issue. I've had a bad crank sensor do this in another vehicle and have heard they were an issue in the '01 model GMCs. Mine stored code p0100. Can anyone point out where the crank sensor is on this engine and the cam sensor as well, provided it has one?
