With the pump installed on engine, check for an audible “click” when the ignition is switched on. 2. If a “click” cannot be heard, check for operating voltage from the terminal. 3. If no voltage, check corresponding electrical circuit (fuse, switch, wire...). 4. If voltage is correct, remove the solenoid carefully, ensuring that the plunger (4) and spring (3) do not fall out.
