    73.5T cold start

    My CSI 73 cold start valve does not have 12 volts going to it when cold , the wire diagrams are not helpful ! does anyone know what triggers this? Thanks . 1973.5 T Sambesi Green !

    Ignition switch on and 12 volts!

    All kidding aside, you must check your relays and wiring. ALWAYS use you hand throttle when starting one of these cars. Always.

    There are BIG wiring diagrams somewhere that are really easy to read. Get you hands on one and I think life will get better for you.

    Good luck,

    gumby,

    The Pelican Parts Web site (http://www.pelicanparts.com/index.htm) has the the wiring diagram you need to understand how this works. Just hit the link on the side labelled "Elec. Diagrams".

    The cold start injector will only activate when you crank the car and you have the hand throttle lifted up.
