This machine has the 4.3 gm vortec engine in it , the problem is it just quit running out of the blue, it has codes 522740-6,522739-6,
522752-9. I have changed both O/2 sensors and the cam and crank sensors,cap ,rotor, and wires, plugs. Still just turns over but not starting. Anyone have an idea where else to check?
