    I had my ecm disconnnted when I was pulling the engine and trans out so I wouldn't damage it. Well now after hooking it back up and connecting the batt my scanner doesn't see it and car won't start and the gauges say the fuel is full (it was only 1\4) and abs is on, DIC is just flashing.

    Is there a right way of connecting the ecm back up?

    Double check the grounds at the lowest transmission stud. There should be the neg battery cable and two grounds. Then at the starter there's the battery cable and two hot leads.
    I drink..so consider that when reading my posts.
