Simply turning key to the ON position does not turn this pump on!.. The fuel pump circuit is designed to energize only when the key is in the 'start' position or the computer sees a RPM signal output indicating that the engine is cranking or running .. There is no emergency shut off system.. As the engine stops rotating, power to the fuel pump is terminated.. The *computer* controls the circuit opening relay when engine is cranking or running which in turn sends power to the fuel pump... Test for fuel pump voltage while a helper cranks the engine.
