Put an obd scanner on it and see if it registers anything (even key on should show power).....and before you do that hook a hot 12v from anything (even just straight off a battery) to the PUMP and make sure they fuel pump wasn't DOA. By far the most common dead part out of the box is a fuel pump.

I did put 12v straight to the wire that goes to the sending unit and the pump turns on.
