2001 8.1L 4x4 suburban stalls dies

[letitrain]

i had the same problem with this stall issue. very annoying. was only 200 #'s outside of the Recall on the problem. took me about a week of deep investigating to conclude the Crank Shaft Position Sensor indeed was the issue. only after completely dismantling all the wiring in the engine compartment. make sure when u get the new one in, it clicks 2 times.... OH, and its not easy without a lift or lowering the trans. i did do it however not removing the trans but i did drop the fuel and trans lines to make my small ass able to squeeze up there to pull it out. its just about an inch away from the bottom of the firewall on the block.
