Ok my brother got a 89 5.0 AUTO, it went out so he got a T5, stock cable, and a ZOOM stage3 clutch.
Ok so we got it all in, went to start and NOTHING....
Clutch switch is bypassed, clutch cable is adjus'ed, and goes in gears fine.. it just wont start...
did you switch the AOD neutral safety harness to a manual one? If not the pink/white wire (Neutral safety wire) to the N/S switch needs to be jumped! in order for the starter to work.
