iv got an 02 tahoe that was running fine and all at once lost all power. It's getting fuel , but not firing. Changed crankshaft sensor checked all fuses it's not security. I'm leaning towards a bad wire connection somewhere. Can someone help me out .thanks

Have you confirmed you have spark to the plugs, and what's your fuel pressure? And confirming that you have starter engagement and engine rotation? "Loss of power" vs. "Not starting"?
