2 weeks ago I had been driving my 1974 TR6 for about 70 miles and it died out shortly after leaving a stop light, about a mile from my house. The car just died out with no warning, and was not running rough or showing any other signs. I checked the fuel and the spark and discovered the fuel was flowing fine, but the spark was not. I am getting spark from the coil, but not at the plugs. I replaced the distributor cap, and the rotor and ignition wires all look fine. The previous owner did install a Pertronix igniter, but it does not appear burnt out. The rotor is rotating when I try to crank the car, but I am unable to get a spark at the plugs. Does a coil send out a continual charge, or is it pulsed and is mine just off time somehow? I am stumped on this one, because it is at the limit of my knowledge on the electrical side of the car.
