I have a 92 Bronco 5 speed. It has MSD Ignition, a stock distributor MSD plug wires and coil. I get a no spark condition when the wire from the coil to the distributor is attached to the distributor, but if the engine gets turned over and the coil wire is laying on the intake manifold I get spark. It appears to be some kind of grounding issue, but the starter works so I'm assuming that the engine block itself is grounded. Does anyone have any ideas why I would be experiencing this problem?
