                                             • Designed for liquid propane injection
                                             • Deliver fuel in same sequence as ignition
                                               firing order                                                 Lesson 4.5
                                             • Amount of fuel delivered is controlled by
                                               the ECM                                           Pressure/Temperature Sensor
                                             • Each injector has an individual ground
                                               circuit
                                             • Each bank of injectors shares a common
                                               power supply
