The mechanical pump is driven by the engine crankshaft, while the electric pump is operated by the pump relay, which opens when the ignition is on. Modern cars have an electronic fuel injection system, which can indicate when the fuel pump relay operates and turns off the pump.The fuel pressure must be within certain specifications for the engine to operate properly. If the fuel pressure is too high, the engine will run rough and rich in fuel, and will not burn all the fuel pumped, making the engine inefficient and become a pollutant.
