How can yo test a coil pack?

[paulgts-t]

Does anyone know how to test the individual coil packs on a R33 GTS-t?

I presume with a multimeter?

If it is with a multimeter what read outs would I look for i.e what range is a healthy coil pack?

Thanks in advance.

Bit hard to explain - I've got a diagram online. You measure between two pins...

ahh but you can get shorted turns as well if u are measureing resisntance or similar...which wont pick up a problem

Sorry i didnt read that article just incase it explains everything...

As what i would do even tho u need to spend $$ albeit not much a 2nd hand coilpac from a japwreck will let you change all 6 coils individually and see if the problem disappears if it isnt your coils then u will have a spare as when u boost up these cars greater heat in engine bay can kill the coils easier and now u have one at hand

if one cylinder aint firing, d/c each coil, one after another

you will find the prob coil easy

to dbl check swap em with the dodgey one, then where the dodgey one is, you will find problem there

thats what i did on my sr

dont think that made sence

GT25, made good sense.

To delve further into GT25's technique, pull out the spark plug and see the color of it after you swap the coil with the cylinder you suspect to be faulty. If the spark plug of the SAME cylinder does not start firing then your ignitor pack or ECU is faulty, not the coil. If the spark plug of the cylinder you moved the faulty coil to starts not firing, then the coil pack is faulty.
