Does ignition module have any control of fuel pump working?

The ignition module does not directly control the fuel pump operation in most modern fuel-injected vehicles. The fuel pump's operation is usually controlled by the vehicle's electronic control unit (ECU). The ECU monitors various engine parameters, including engine speed, throttle position, and oxygen sensor readings, and adjusts the fuel delivery accordingly. The ECU then sends a signal to the fuel pump relay to turn the fuel pump on or off, as needed.
