During cranking the fuel pump relay is activated by the starter. Once the engine is running the fuel pump relay evaluates the engine speed signal "TN' for engine speed of 300rpms. If that condition exists the fuel pump is continued to be energized.

I have had 190e 2.3s that had an ignition controller problem that caused no speed signal. Without speed signal the fuel pump relay shuts off.
