[drolston]

Pull the coil high tension wire out of the top of the distributor cap and hold the end near a ground. Should get a blue/white spark to jump half an inch. If no spark or weak spark the coil is bad. If you get a good spark there, plug the coil wire back into the distributor cap and test the spark at one of the spark plugs. If no spark or weak spark there, check the distributor cap and rotor for broken or burned. Make sure the little thingy in the center of the distributor is in place and that the contact on the rotor reaches up far enough.
