No Start, No fuel pump

Just picked up a 2008 Screaming Eagle Ultra Classic. The bike will not start, and I do not hear the fuel pump kick in. also there in not power at the 15 amp fuse for the fuel pump. Not sure if that is the problem though as that fuse may get power after a relay closes? fuse is good. Any other ideas?

No start, no spark, no fuel pump.

working on my 2008 screaming eagle ultra classic that I just got. Engine is a no start. I do not hear the fuel pump kick also checked spark and am not getting spark. checked fuses and all have power except no power at fuel pump fuse. Tried to pull codes on speedo display. when the display is supposed to display "diag" all I get is "iag" also on the next step is does not show the identifier for the efi module, does show the rest. I presume possibly that location us burned out on the display. if I try to read the codes for efi hold in the button when the identifier for efi should be flashing even though it does not show I get the display of "no ref" Appears to me that I am having a problem with efi power supply???? would like to know how to check power and grounds for the efi module? Or any other thoughts?

How are you testing the voltage at the fuel pump fuse ? That fuse only sees voltage for 3 seconds or unless the engine is running. After turning the ignition on without starting the engine the pump will only activate for 3 seconds.
What about the rest of the electrical system ? Lights work etc. ?
Try tightening the battery cables and make sure the battery static volts is at least 12.8v.

Sorry for the double post. My first post in this fuel system forum is in regards to the fuel pump not kickin in at key on. As I continued testing and learned how to check codes, found no spark also, and found that I don't believe the efi module is communicating. I thought that post would fall under electrical??? At any rate I will check power at the 15 amp fuel pump fuse at key on. Yes, the run/stop switch is in the run position. I to have fell victim to that in the past.....

To test the volts at the fuse you'll need to have the tester leads hooked up prior to turning the ignition on because it'll only show a measurement for 3 seconds.
If battery static volts measure 11.6v or less with the ignition on the ECM won't energize the system.

testing with blue point multimeter, negiative clapmed on battery negative, and positing on the back of the fuse, then turning key on. 0v displayed.
