We have replaced the coil, cap, ingintiion and we get spark at the Coil but we don't get any spark down the wires to spark plug, What may cause this. The wires are also new.

We can't afford another car since my husband has been out of work for over a year now. Please help

Thank
Terry

Welcome to the forum. You have a coil wire that goes to center of distributor cap from coil? If you unplug coil wire from cap and hold close to engine ground, if you crank the engine, can you see spark jump from the coil wire to ground? If so and no spark at plugs, I suspect the cap and or rotor. The rotor does turn, with engine cranking?
