Question type: Maintenance & Repair
Running yesterday test drove it. We park it and the next day we turned it on and it wouldn't start. Replaced the fuel pump and the fuel filter,it still wouldn't start.There is no gas flow to the throttle body. It will turnover but won't start. I'm thinking something to do with the wires.

ther is a fuel pump relay under the driver side dash chang it
I agree with MRC40. There's a Main Fuel Relay located under the dash on the drivers side. There's 7 wires to the plug that feeds into the relay. It's smallish in size, but it's only held up by a single nut. It might be hiding behind a big silver box for the cruise control. Anyways, pull that Main Relay out and either take it apart and re- solder the connections, or drop $70 for another one at Autozone. (If you can get one of your electronics buddies to do it- even cheaper than buying new.) Another idea- check all your fuses, even under the hood. Last idea- there's a ground point near the thermostat housing. Make sure that ground point is clean, un-corroded, and the 10mm bolt is tight. That ground feeds much of the electronics for the fuel injection. Oddly enough, it also feeds to the Main Relay for the fuel pump.

What would cause my Honda Goldwing 1500 special edition fuel pump 2 keep running
Possibly faulted closed relay - fuel pump relay directs current to fuel pump regardless of ignition position. Could also be a short from another circuit to fuel pump supply. Try replacing fuel pump relay, then inspect wiring for shorts if that doesnt work.
