    Trailblazer 302 starting problem

    Had a similar problem on wife's jeep. Found poor connection on trigger wire at starter. Was loosing connection where eyelet was crimped on at solenoid terminal. If I would wiggle wire harness wile she held starter in it would start.
    Crimped on new eyelet works fine.
    Just another thought

    I would...

    first disconnect the battery and trickle charge it overnight

    would also clean the connections to the starter and switch...

    don't forget the ground connection..

    Batt voltage seems low ... fully charged should be around 13.8 vdc

    Check fuse F6, and replace if open (see Section 8-11).
    Check battery voltage.
    Check battery connections and tighten if necessary.
    Check plug PLG5 and plug PLG8 connections.
    Have Factory Authorized Service Agent check Engine Control switch S2.

    Got a VOM? Start by checking for battery voltage at the battery and then at the ignition switch and then at the starter engage terminal in START etc.

    Have you checked to make sure you battery connections are good? On both ends - at the battery and starter/ground?
