As long as I have a volt meter on the power terminals of the fuel pump, it works perfectly and the engine runs.. as soon as I take the volt meter away, the pump stops working and the engine dies.
I think I'm pretty smart, but there must be some mystical electricity stuff going on that I just don't understand. Anyone have any ideas?
