I am doing a 2.8 - 3.4 swap at some point I believe something happened to the harness during the swap. I have fuel. I have air. I have spark. I have set the timing and triple checked it multiple times but it will not start. The only thing I can figure is the harness. If anyone has a harness for a 2.8 tbi please let me know. Or if anyone has any ideas I can check let me know.
