Study Notes
Engine Primer System
- Each engine's priming system includes a solenoid-controlled valve, fuel lines, and primer jets within the intakes of three of its cylinders
- The system is activated by turning on the corresponding electric fuel pump, which supplies fuel to the primer system
- When fuel pressure is present, pressing the primer button activates the primer solenoid valve
- This action allows fuel to travel through the lines to reach the primer jets within the intake of the three designated cylinders in each engine
