What could cause the fuel getting to the throttle body but none at the injectors

Yes. It will run if I pour fuel directly into the throttle body. After doing this, the fuel injectors would drip a little fuel at the next priming cycle, then completely stop again. It was running just before the simple changing of the filter in the return line. The pump was replaced two days ago, so it is new. Also checked to make sure the filter flow direction was correct and it is hooked up correctly.

In that case injector pulse 'should' be ok BUT needs to be tested..along with fuel pressure so you know where you stand! Have you checked flash codes?.. Key on.. Off .. On .. Off.. On. and watch C.E.L. flash out any possible codes??

Out of ammo!!
