The misfire causes unburnt fuel and air to pass by the oxygen sensor. The sensor sees the oxygen and thinks more fuel is needed, so it adds gas. Focus on the misfire, bad spark plug, ignition coil, plug wire. A clogged fuel injector also causes a misfire but less common.

Do I have to have the brain relearned after swapping out motors.


If everything on both engines were the same, no reprogramming should be required. The engine should start, and it may take a few minutes for the engine to run smoothly since there are going to be some differences in the way the "new" engine performs. I would guess that there is some connection to the engine that is loose or missing. You said it has fuel and fire. The only other thing needed is air. And unless you are in a vacuum, it should start.

Brain box


It could be the ignition module or brain box, but I doubt it.
Your complaint sounds more like weak spark plug wires and dist cap. Have you inspected or replaced them yet ?

If, when you are attempting to start, the fuel injectors are firing; then it should be ok. What exactly are the symptoms your truck is experiencing?
