ignition problems HELP

I have a 1987 Bronco II 2.9 I have replaced the coil,distributer ,tfi module ,ecm,and relays .Getting fire to the dist.but not to plugs.I have tried everything short of trying to find a wiring harness.it will not crank.Checked everything with ohm meter any suggestions

if this is a crank, no start with spark in the primary ignition system; the next step is the secondary ignition system. i would start with the coil wire. resistance should be very low.
