    Does anyone know if a 2001 Ram 1500 with a 360 would have what I believe is referred to as a cold start injector?? Its an additional injector thats function is to spray extra fuel during start-up in cold weather for easier starting. Thanks!!

    Never heard of that one! On a fuel injected gas motor, it should fire right up in cold weather. Never had a problem.

    I had never heard of it either, but a guy told me Dodge used to put them on back in the day, and was wondering if my '01 had such a thing.

    Never heard of one....The powertrain controller will alter the injector pulsewidth according to the engines needs (cold starts included)

    Cranking injector pulsewidth is somewhere in the 5 millisecond range, idle is in the 1.2 -1.5 range.
    Disclaimer......memory may vary from actual measurement:dizzy:
