1998 GMC C1500 V8 Two Wheel Drive Automatic

My truck just sputtered and died. We have chaged out the wires, rotor, and cap, distrubutor, module and coil. And I am still gettin no spark when checked with lite? What else could it be?

Already replaced the sensor three times used a scanner and crank sensor keeps coming up. I got the sensor at oreillys do I need to get one some where else or is there a specific brand to use

Check the wire back to the computer for short and open if okay could be the computer. Make sure the CPS is installed properly.
