Default Ls1 conv whole bank not firing?

As title suggests, putting a ls1 into Aussie nissan patrol. Engine fired up fine, could tell it wasn't right. But the whole 4 cylinders on the passenger side aren't firing. The pipes are Luke warm to the touch and when ign is on there is no power to the coil(s)
Any ideas? I've missed something but not sure what. Thanks in advance

Do you have your Coil or Injectors fused for each bank ?.. check the fuses and connectors.

You should check to make sure your getting a pulse to the Injectors, use a NOID light. Check the power to the Coil with a DVM.

I only have fusses on the ign and power feeds into the ecu. I went and checked and although I haven't got a noid light, with a stethoscope it appears the inj aren't working either. There was also no continuity to earth on the indi coil conn?

Sounds like the Pink Power wire on that whole Bank is not getting 12v...it powers both Injectors & Coils.

Ground in there goes thru the Harness to the ground points.

Who did the Harness?

Yep, check the grounds. Each bank has its own ground wire that ties in at some point. It is the black wire from each main connector(2). As stated it could also be the supply voltage. You now have your homework assignment.

Harness issue. Injectors get keyed 12V+ with the ecu providing the ground. Who ever did the harness missed hooking up the pink wire to that side.

Yep definitely a pink power wire issue, just had the same type of issue but it was a weak ground on the passenger side. Good luck.
