After vehicle clucked to a stop and towed, was informed that the new distributorless integrated system (coil) has failed... answer: replace same. What really happened: The vehicle would start but the coil would only allow power to flow through and to only 2 out of the 4 spark plug wires. Thus: only two valves working. Changed crankcase sensor, cam shaft sensor, new plugs and wires, another coil pack brain box still operational BUT OH NO still the same thing, power only flowing out of two spark plug wires???????? perplexed!
