    I have the secondary fuel pumps being activated with boost in "Programmable On/Off Outputs 1".

    Is there any way to test this circuit in TS to make sure they are being turned on?

    Yep, CANBUS/Testmode menu at the top, output test mode - I/O.

    I'm not sure this is doing what I want.
    Yes, a fuel pump is turning on but I don't know if it's all three or just the two that are wired on that circuit.

    There are two areas that I can activate a pump but they seem to be activating the same pump..or at least the dual pumps sounds the exactly same as a single pump. I'm running three 450 pumps with two coming on with boost so I would think the two pumps would sound a lot different than one pump

    I'm wanting to make sure the MSPro is activating the secondary pumps so I was hoping I can do it without the primary pump running.

    I could disconnect the primary pump relay if needed but I'm hoping TS can test each circuit separately.

    Thoughts?

    Never mind..

    I went in and reversed the secondary pump activation so it is initially "ON" instead of "OFF" and they turned on. Naturally I turned the settings back when done...

    Yep, it sounds a LOT different with those two pumps flowing..
