Hey, I just changed the spark plugs, wires, rotar, and distributor cap in my '76 Z. After that my car wouldn't fire. SO, I replaced the parts with the originals. Everything. And now it still doesn't fire. Tested for spark, its sparking, labeled the wires before I pulled them, pulled them one by one. Nothing works. Has anyone had this problem before and found a solution? If so please let me know. Thanks.
