This 4.3L engine? Note the diagram. The pink wire at ignition module, is it hot with key on? It appears both fuel injector fuses are involved with ignition. Any applicable trouble codes? Do you have fuel injector pulse with engine cranking? Does the distributor rotor turn when you crank it? Is the coil wire ok?
