I am at a loss right now. My 7.4 just won't run right. I have taken the spark plug out of the 2 cylinders and started the truck with them hooked to the spark plug wires. Both of them have spark but are not igniting. The truck still misses on the 2 cylinders. I have changed the 2 injectors out for those cylinders and also changed the wire harness for the fuel rail and still not igniting. These are missing on the same side. Has anyone had this problem? Please help!
