Do you have power to the coils with ignition on? Each bank has a common power.

They're meant to have 12v supply.

You still haven't worked out if pcm s getting signal or not with noid light when cranking.

@ [B]Not_An_Abba_Fan[/B] - Someone in North Coast of NSW. Will not reply to emails or phone calls, does not help me when he won't help.
@gtrboyy - When cranking the injector does not flash. When ignition on power to the injector. No signal at crank.

However i checked the crank sensor power at ignition it was very faint, same at cam sensor, however at injector signal is strong.
Could this be an issue that crank and cam sensor signal is low?

Yep definately sounds like something amiss.

Think you have start all over from beginning by checking wiring is correct from ls harness to car...then check if correct cas (2 types) for engine/pcm.

After that you'd be questioning pcm or tune with vats is actually off ( yes again)

What model is pcm & engine/harness from? All from same donor car or mix n match parts?

Did dude who did harness conversion also put in obd2 port so you can use scan for faults or get it tuned?

Post up a pcm wiring diagram then go from there.
