Remove and replace the coilpack plugs 1 by 1 and it's the cylinder that doesn't change the engine note.

When you have found the faulty cylinder you can then run further tests to determine the cause.

Injector

Coilpack

Spark Plug

Wiring

Compression (Valve or Rings etc)

CAS

is it getting spark and fuel? switch coil packs around and see if it follows the coilpack, if not switch injectors and see if it follows the injector.

So have you tested for power to coilpacks and power to injectors?

yep there is power havn't checked the injectors tho how do you do that?

& yer i'v tryed changing coils but still no go!

Unplug all the injector connectors except no.3

Remove the CAS, turn on the ignition and rotate the CAS drive. You should be able to hear the injector 'ticking'

If it does not, then you need to confirm that there is power to one of the wires on the injector (I didn't understand your last reply as you said there is power but then asked how to test it)

If you have power to injector but no pulse, then do a resistance check on the injector pins (on the actual injector pins, not the plug wires that go back to the ECU)

For the Coilpacks, there is 3 wires. The thick wire that goes to the + mark on the coil is the power. Test for 12V there. You can also hear the spark fire if you unplug all the injectors and rotate the CAS drive again.

What engine is in your car? Is it the RB30? or do you have something different?

If it's the 30 then you will have a distributor and leads. Same deal but no individual coilpacks. Need much more information if you want more help

rb20 redtop

will have a go at that tomorrow & see what i come up with

Even if the injector is ticking check that there is the same voltage across all injectors, I had faulty wiring on #5 (my fault) but it still ticked, fixed the wire and it was all good
