I have a 2002 gmc sonoma that wont start and im looking for the wiring diagram ignition control module . i have replaced the fuel pump the coil packs ,plugs , plug wires starter i need the wiring diagram to go any further does anyone know where to get one?

 

did u also replace the rotor and rotor cap?...sometimes, even tho u cant see any cracks or issues, they go bad...also check the coil-see if it is sending current to the Distributor...other than a Haynes or Chilton's book, I havent been able to find wiring schems for 4.3 V6 vortecs online either(am assuming, since u did not state, that is what u have)
