[QUOTE="Frankie, post: 2424447, member: 230928"] If the engine has no spark, check for voltage at the coil positive terminal when the ignition key is on. If there is voltage, the problem is on the trigger side of the coil (pickup, crank sensor, ignition module or primary wiring circuit). If there is NO voltage at the coil, the problem is on the supply side (the ignition switch or ignition wiring circuit). If the coil has voltage, the problem may be a bad high voltage output wire from the coil to the distributor, hairline cracks in the coil output tower, or cracks or carbon tracks inside the distributor cap or on the rotor (if equipped).
