    i think in the scanner turning on the pump just does its normal prime time and thats it, i usually just put say 180 seconds in the prime time and flash then just turn key on, just dont let it run dry u can kill the pumps real easy

    I worked on a fuel test program where we had to drain and refill 20 cars, three times a day. This is how we did it. Never hurt a fuel pump. Some GDI cars would throw a low fuel pressure code, but that's it.
