Engine cranks but no start

Few days before this happens, my Chevrolet truck was park in the driveway, it has problems that it cranks but no start. So I have placed a new coil and resolved the problem.
And now I drive the truck around then it stops in the middle of intersection, the problems came back the engine cranks but no start, and so I have it towed to my place. So I changed the following, new plugs, new plug wires, new distributor but the issues remain the same, It has sparked on all the plugs and the coil. I still have these problem it cranks but no start. Would like to know if these truck is equipped with Electronic Spark Control Module.
