What is going on here, Are we all having the same problem, our trucks crank then die immediately. I thought it was the fuel system, but now im thinking its the vehicle anti theft security . Im gonna replace my fuel pressure regulator if i can find the darn thing. if that dont work , its gotta be the VATS. Im glad im not alone wiht this problem. If i figure out the exact problem ill let yall know.

Don't forget about the Crankshaft position sensor. Mine went bad and caused a no start condition. 1998 K1500
