PROBLEM WITH FUEL PUMP WIRING?

Was driving down the road and the Honda suddenly quit. The first thing i tried was to restart the car, but it would only crank but wouldn't start. So I towed it to the local garage and they said it was the pump. So i left it with them to fix it. They called me back and said that the pumps are fine and it might be the wiring to the pumps. They stated that when they had it on the hoist that it would run fine when it was connected to their computer but once taken off it wouldn't run anymore. Does anyone have any ideas on what this could be or what would cause a problem such as this? Also any idea on where i could find a wiring diagram online for "free" Any help with this would be much appreciated.
