I recently Bought an 04 trailblazer 4.2 Got a used engine and replaced it and now i have a no start condition. engine will run off of starting fluid fuel injectors will not fire. got good fuel pressure all the way up to the rail

The fuel pump is running when ingnition is turned on,( tested fuel pressure at the test port got 45-50ish
I have fuel up to the rail so the lines are not blocked, (took them loose from the FPR and turned key to acc. fuel flowed pre and post F.P.R. )

so i think that for some reason my injectors are not firing.
low engine power light comes on along with check engine light
