I had the coil wire removed to make sure it was not driven. Someone tried to start it with the wire removed. When the wire was replaced it would not start. There were no problems before. It has a 350 engine, 4x4 and has 80,100 original miles. I undid the battery to reset the computer, I had the ignition module checked, I tried a new coil. I am not getting spark from the coil and all connections are good. What could it be?
