No voltage from PCM fuel relay trigger

This came out of nowhere. I've had it hooked up for several months now and it's worked really good. Now I'm not getting any voltage from my PCM trigger to my fuel pump relay. If I wire around it, the fuel pump kicks on. I've been all over checking wires, fuses, grounds, etc.. and this is baffling me. In a desperate measure, I tried replacing the crank sensor and still nothing. I've read where guys have encountered this kind of issue theirs wound up being wired wrong or a grounding issue. I haven't changed anything up, so I'm at a loss.
