    Ive got a 96 Vortec 350 in my K5. When you turn the ignition on, the fuel pump runs like normal, for about 6 seconds. Now, its also running for the same 6 seconds when you turn the ignition off. Anyone have any ideas why its running with the ignitioin off?

    AFAIK it is common for the pump to run a few seconds before and after the engine has started.

    It's to keep pressure in the line I believe.
