Good question Michael. Maybe the pump has to work harder when the engine's
running, although it seems it would simply have to fill the carb bowls, and
then stop. That would imply it draws the same current, regardless of whether
the engine is running or not.
Strange ....
Let us know what you find!

Michael, you probably have a high resistance wiring line. Your test shows
12-V, but that's under a very lightly loaded condition, as the test lamp
draws very little current. When the pump draws current, the voltage at the
pump is droppng, somewhere along the 12-V feed.
Check the connections at either end of the fuel pump circuit, and especially
the ground connections.
Alex--
Sounds like a concept but if I may ask, why does the pump run okay with the
ignition on and engine off but then cuts out as soon as I start up? Because
I have run the bowls dry the pump is pumping quite hard when I turn the
ignition switch on? In any case, pulling a new wire from the fuse panel was
my next step. I have been using the same ground with the pump hotwired to
the battery so I think it is okay but I will check that as well.
Thanks--Michael
