No, an ignition control module does not have a direct impact on fuel injection. The ignition control module manages the spark timing for the engine, while fuel injection is controlled by the engine control module (ECM) and fuel injectors. A faulty ignition control module can affect the engine's performance and cause misfires, but it should not directly affect fuel injection.
If you suspect a problem with fuel injection on a GM throttle body, it's more likely to be caused by issues with the ECM, fuel injectors, fuel pressure, or other related components. It's important to diagnose the specific issue accurately before attempting repairs to ensure proper engine operation.
