I never ran codes I couldn't find the hookups. Went to leave motor wouldn't start would crank but that's all. What do you think bout the inertia switch I did hit the reset button when I was looking for the hookups wich i should of known they wouldnt be under the dash. maybe that jus finally wet bad I herd they cut spark off to when they go bad. Iam really jus thinking bout the 5.0 swap.
