Fuel Injectors

Battery voltage is supplied to injectors via a 12 amp circuit breaker located in the electronic control box (above MPI ECM).

Power supplied to injectors does not use external resistors. Due to sequential fuel injection, a separate power output stage is provided for each injector.

MPI ECM controls opening time of injectors by supplying a ground for each injector.
