I just put a new fuel pump, filter, relay and fuse on my truck and there is no power going to the pump. Also I found out that the old pump still works. So I am wondering what would cause the pump to lose power.

It sounds like the fuel pump relay needs to be checked here is a guide and the reay location so you can run the test.
