02 dodge ram van 3500 crank no start

What is your question?

Hi My van crank but doesn't start and I found out that the starter coil is receiving the signal from PCM as well as getting the necessary voltage from the battery, however it is not sending anything towards the distributor. What could be preventing it from doing so. I have changed it 3 times as well as changing the following: Distributor assembly (including the camshaft sensor) spark plugs spark plugs wires crankshaft position sensor Fuel Pump New factory recommended battery Tested the alternator (good) Tested the PCM (good) All fuses and relays are also good Any help would be appreciated. Thanks
