    Installing New Vanguard 28EFI No fuel pump ground

    Thanks to everyone for the input and information. I finally got time to install the MIL late this evening to see if I could read any DTCs.

    Installing New Vanguard 28EFI No fuel pump ground

    Installing New Vanguard 28EFI No fuel pump ground

I have no safety switch issues that would stop fuel pump from being energized. The engine cranks, I have spark, but...

    Try plugging a drill in while gen set is running, pull the trigger on the drill and spin the chuck by hand. If it works the drill will start running so watch your hand. Good luck
