Does anyone know a place that can test coil packs to make sure they are working properly!!!!

I am trying to rule one thing out at a time at the moment to find what is wrong with my car!!!

connect an earth lead and a positive to the coilpack top, then put the live bit of the coilpack on your tongue

it works, honest! >:(

(If it works with a 9 volt battery.....)

have you looked for the error codes on the computer first ?, checked the grounds and plugs for corrosion, pretty common?

From what I have read around the place bench testing them isn't worth it.

If they are only charging $50 to do them they aren't testing them under load or at working temperatures. My guess is it's just a resistance check which can't rule them out as a problem, only at times confirm they are a problem.

Swapping them out is by far the cheapest and most definative way. Even if you can only get 1 known working one it doesn't take long to swap it through the 6 different positions. Once you have the coil cover off you can squeeze them in and out without having to undo anything else. All up it should take 2 hours max- that's if the last one you test is the one that's gone. I recon I could do all 6 in my stagea in under 1 hour

Also, if you cut off the lip at the back of the coil cover you should be able to get it in and out without removing the crossover pipe making future work easier.

Edit: not sure if you can get then in and out as easily on a R34, I've only done it on an R33 S2

Just FYI there is a place that does this & last I knew, they did it for less than $50.... although it may cost that much by now.

The place is called Petro-Ject, located in Stepney (Ph: 81321622).

They will do testing on individual coil packs & heat them up to full operating temperatures & under high load. The guy that does it all has being doing the same kind of work for something like 12 years now & knows his stuff.

And just let them know that Jared sent you :D

thank guys, i have an intermittent missfire and no one seems to be able to rule anything out as there are no error codes coming up.

i have split fires already and they have done less than 5000kms in 18 months, so if it s them i wiil be pi**ed.

Would almost have to be a defective coil pack after only 5000kms for them to be the issue. What boost & spark plugs & gaps are you running?

Do you have the original coil packs? I'd suggest you'd try these first if they worked ok when you removed them.

The car spent 6 weeks in a mechanics trying to sort it out and all they came up with is that one of the ciol packs is slightly faulty as no error codes came up.

Just want to try and sort something as it is detracting from driving the car and my enjoyment.

Boost is only 10 psi and a .8 gap has been set with a fresh set of plugs as done by my mechanic.

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
