    CTS 2005 Starting problems

    I have a 2005 CTS 3.6 Litre engine with 6 speed Manual gear box.

    Occasionally the Car will not start, despite the fact that all the elements connected with starting are new , from spark plugs to battery, to starter to all.
    I also checked the Switch that exists below the Clutch pedal which completes the starting cycle, and lubricated it...

    When the car refuses to start, I turn the ignition on, then I connect an external wire between the positive pole of the battery and the main wire situated in the Relay box in the engine compartment (It is a thick wire and it has a Lilac Colour).
    The car starts and all becomes normal.

    So once I jump start the car the way explained above, I have no problems with all subsequent attempts, until I leave the car un-driven for few days where I have to jump start it again.

    I will be grateful if any one would advise me on this problem and what to do about it having faced a similar situation.

    Thank you

    Just a guess here, but you may have a sticking relay somewhere. I'm not at all familiar with the starting or electrical system in this vehicle though.
