Dodge: Motor has no spark, dodge ram truck, feeler guage

Question
I have a 1986 Dodge Ram truck that won't start, I have power up to the distributor cap. I've have tested the electrical system with a meter and replaced just about everything including the distributor and rotor.  Motor will crank, but has no spark, will not start.  PLEASE HELP!  

Answer
RanMan,
This could be caused by a bad coil.A bad connection at the coil or distibutor,The pickup coil in the distributor could be bad,The coil has to be adjusted to specs in order for it to work.The gap on this is 0.006 in.You have to use a non metallic feeler guage for this,do not use a metal feeler guage.Or it could also be the ignition module.One of these is more than likely the problem.Sorry it took me so long to answer.Thanks RamMan
