Pump Problem

2003 VTX. She's sat in the garage for 6 months while i fixed some other problems. Put everything back together today and I did not hear the whine of the pump when the ignition turned on. There was enough juice in the battery to crank the starter but it would not turn over.
Voltmeter shows 11V to the pump connection.
I took the pump out and hooked it to a 12 V battery and you could hear it pumping. Hooked it back up to the bike, turned the ignition . . . and nothing???

Start with a good, fully charged battery. Then start further troubleshooting if needed.

Hook the gas line from the petcock to the carb. The pump is not needed. It will run just fine by gravity.

Garage
Voltage at Green and Brown wires at FP connection with pump connected??
Several pumps over the years needed a thump to get them going again.
Try it, see what happens.
Charge the battery.

Do you have a fuel manager and is it getting power from the rear running lights? If it is, check to see if your rear running lights are on. Blown fuse to the rear lights, no power to the fuel manager and no fuel pump. Don't bother trying to start the bike if you don't hear the fuel pump prime, There's no fuel and you'll just waste the battery

Break lights and rear running lights are on. Is there a fuse for this pump itself?
