No spark at plugs

Back about three weeks ago, I changed the distributor in my truck. The old distributor had a crack don the shaft. When I replaced the distributor, I also replaced all spark plugs, wires, Ignition module and coil. Truck ran perfect until yesterday it just quit going down the road. Got it pulled home and hooked my OBD2 scanner up to it. Only codes showing are faulty coolant temperature sensor and high voltage at ignition module. Changed TCS and took new ignition module off and had it tested. It is good. The truck has spark coming from the coil to distributor, but no spark at the plugs at all. So took cam sensor out of distributor and replaced it with another new one. Still no spark at plugs. But coil is firing with a hot white spark. I am kind of stumped as to what else would cause no spark at plugs if coil is firing. Any suggestions on what to check next? Thanks in advance!
