E30 Zone

Hi guys, pulling my hair out now on this e30, I've changed the injectors a number of times, as well as a new fuel pump, dizzy cap, it's getting spark, ignition timing is roughly there, but it wont rev, as if its miss firing

I've had the injector rail out with the injectors facing up, noticed they dont fire 1342, they fire at the same time, is this my problem or is this normal?

Normal.

Thanks, at least that's peace of mind as it's been niggling away at me! Process of elimination now then
