When the ignition switch is turned on the pcm turns on the fuel pump by energizing the fuel pump relay. The PCM keeps the fuel pump on as long as the engine is cranking over or running.It does this by recieving pulses from the ignition module. If there are no referance pulses the PCM will turn the fuel pump relay off in 2 seconds with the ingnition on.

Most models also include a secondary control path through the oil presure switch witch will turn the fuel pump on after it detects oil presure.cranking time will be longer if the fuel pump doesn't recieve current until oil presure switch contact is closed.
