Me and my buddy have started on his car it was an original 4 cyl coupe body but we put his 5.0 out of his wrecked mustang in it we swapped the harness under th hood with the computer for the engine and nothing worked so then we swaped the entire dash wiring now the car cranks but the fuel pump doesnt kick on and the distributer doesnt send spark to the plugs the coil send it to the cap thats it if you have any idea let me know
