I have an 84 x-cab p/u 4x4 w/22r. Replaced head gasket, engine ran, finished putting back together & now no spark. Have power from ign. switch to igniter, from igniter to coil, from igniter to distributor. All parts ohm correct. Tried replacing coil, ignitiion switch, p/u coil no change. Cannot find igniter in town. Before I spend countless hours & money hunting parts, need to know if anyone has any ideas? Help will be greatly appreciated.
