So my engine just died going down the road the other day and wouldn't start.. my fuel pump has no power going to the blue and black wire. the efi relay has power to it but their seems to maybe be a break in the circiut between the relay and the pump. whats next any ideas?

Pull the relay and bench test it to make sure it transfers power to the pump when energized. Input to the relay just switches it, you need to make sure it outputs power. The input power and the output power are separate circuits.

I agree with Stillrunning; think relay first. If you are stuck on the side of the road, pull out another relay with the same numbers on it from another nonessential system (a system that you know is working) and try it in place of the current fuel pump relay. If there is still no power at the pump, you most likely have a wiring problem.
