I haven't read the Factory manual completely as yet but I have noticed that my FD will stop pulsing the primary #1 rotor injector after about 5 seconds of cranking if the engine fails to start. Then after 2 seconds it will begin again, that fact seems to be unclear. If you stop cranking and start again the injector pulses once again for its 5 seconds or so and off again. Is this in the programing? Is it for the flooding issues??
