    First off all, thanks Marc for your help earlier, you figure with what we came up with it would have fixed it... Here goes...

    88 GTS, 3SGE...

    Will not start in cool/cold weather. I crank it over till the battery dies... nothing
    Go out when it is warmer in the afternoon, starts right up.

    Replaced the cold start injector, cold start time switch (brown plug sensor), and EFI temp switch (green plug sensor), both known working spares.

    Checked for bad wires, checked grounds (all I know of and can see)

    Changed fuel filter/air filter back to standard paper, removed K&N

    Checked timing

    MAF seems to be working, or else it wouldn't run at all.

    Higher octane gas, mid grade.

    Fluids up to level and spec.

    Am I missing something ????

    Nope... Has to be around 50-55 before it'll start.
    I finally got it to start a little bit ago, but it took a couple minutes and my starter box hooked up to keep the battery from going dead...

    maybe the iac valve on the bottom of the tb? maybe stuck or something? cold start injector?

    starting to wonder if maybe the iac's are starting to go and causing wierd issues.
