96 S10 Blazer Has Spark To Distributor Cap But None Out

My brother in law has a 96 s10 blazer and it has spark coming out of the coil, to the distributor cap, but nothing coming out to the spark plugs. He has replaced the distributor cap, rotor, plugs, wires, ignition module, coil, cam sensor. doesn’t make sense to me so i thought i could get others opinions. thanks
the module under the rotor has been replaced, the guys at napa called it a cam sensor, if that is not the name for it, then the cam sensor hasn’t been replaced. Thanks for your comments though….. hope to find the problem
