Hi all, I have a strange one for you... I have a 1988 F-150 with a 4.9 liter inline 6 which suddenly died in traffic and will not restart. After eliminating fuel and air as problems i turned to spark and soon realized that the rotor was not turning when the engine was cranked. I pulled the distributor and found that the shaft turns easily and does spin the rotor stator and that the shear pin is intact on the drive gear. At this point i am just about at the limits of my technical expertise. Is the distributor powered by the camshaft? When i crank the engine while looking in the distributor hole, the gear that aligns with the distributor gear does not turn. Any help would be greatly appreciated. Following are any specs i can think of that might help. Please let me know if any more info is needed. Thanks much
