If you open the MPI Relay box,you`d see it`s basically 2 switches.They make contact when they see 12v power,which magnetically pulls the arm over to complete the circut.When the key is turned to the "on" position,the ECU gets power.When the ingition is turned to "start",the fuel pump powers.The click heard after shutting the car off is actually the ECU power getting shut off,the arm clicks when contact is broken. I had some bad ECU/MPI issues when i 1st got the car,which taught me way too much. ![shuffle shuffle](/forums/images/graemlins/default/shuffle.gif)
