Ford Repair: electrical problem, side fender, 351 windsor

Question
Engine 1988 351 Windsor  (very low hours)
Engine turns over, gas to new carb, fires but will not run.
This seemed to be an intermittent problem prior to date but has since become a 100% failure issue.
Checked voltage to and through ignition switch, battery, etc. All is OK. Cannot get any reading at the battery side of the coil where there should be 12+- volts? Perhaps this is the trouble spot and if you agree what could cause a disconnect to the coil?

Answer
this vehicle is a little out of my range but i'm pretty sure this truck has an ignition module that can fail and do what your saying. it is located on the right side fender well looking at the engine. it's a grey box witth two connectors coming out of it
