GeneralDisorder Posted January 19, 2021 Share Posted January 19, 2021 The distributor contains the crank and cam optical pickups that the ECM uses to sync up and fire the ignition and injection. Make sure it had power, ground, and check the square wave output with a scope. Likely a power or ground issue. Check all the power and ground circuits for the ECM.
