VR V8 Bad Miss

[Grunt1969]

Hi guys, need some help. I own VR V8 dual fuel and cannot get it run right.Have installed new spark plugs, leads, dissy cap, rotor button, air filter, fuel filter and checked timing.Still running like on only 4 cylinders.Well to my disbelief, it is.Remove No 1 fuel injector wiring and engine does not miss a beat.No pulse when checked with test light.So checked the remaining injectors and spark plugs and found that only Cylinders 2,4,7 & 8 were firing.No injector pulse on Cylinders 1,3,5 & 6.I have also replaced BCM and matching key fob previously.My Question is why/how can i get a pulse on 4 cylinders and not the other 4.
Any ideas or similiar problems/remedies would be greatly appreciated.

broken wire on the drivers side injector harness somewhere id guess

Thanks DD, that could explain 1,3,5 not working, but for 6 not to be working.HMMMMMMMMMM

pulse wire broken somewhere or possible faulty PCM.

pretty sure VS 5.0l's run grouped injection, fired in two separate banks, rather than all at one or sequential.

Thanks wamboin23, so do i source another injector loom or pcm.Anyway to test or repair.
