First of all the EFI Harley fuel pumps only run for 3 seconds when the ignition is turned on then they turn off until the engine starts.
Did you check for codes yet ? The procedure is in a sticky in the electrical section.
Post the codes and we can diagnose the symptoms from there.

I got a 2007 Harley-Davidson Sporster XL. Everything is fine with her ex-cept the Fuel Pump will not come on at all. All the fuses are fine. Checked all cables and wiring. Even with a Parameter for where all the Plugs plug in. The Fuel Pump come on every-time when i hook it stright up to the Battery. But i hook it back up to the Plug. Nothing. But with the Parameter is shows there is Power. I am Lost right now. Does anybody have any Ides? Thank's.
I have the same bike and the same problem. Do have 12 vdc on a pin of the tank plug when I push the kill switch. Let me know what you find. Mine was running find and then I got stuck on some sand afterwards it will crank but no fuel pump noise and no start.

Unless the bike fell over, when you got stuck in the sand, there would be no connection. But if it fell over, the tip-over switch could have activated and stuck.( it.s a ball that rolls over contacts and turns off the bike to prevent pumping fuel all over hell and half of Texas after a fall.)
