was around a fellow members house, trying to help diagnose a cylinder out.

 

Checked spark, there is a spark, checked coil pack, the coil pack is fine, checked basically everything, when doing the screw driver test on the injector, you cant here it, the spark plug is dry and not wet, even changed spark plugs with a known working one, changed the coil packs with a known working one, it makes no difference if the coil pack is plugged in or not, the cylinder isnt firing, i checked for corrosion on the injector plug, but its clean, infact really clean lol, and checked the wires.

 

Only thing i couldnt check was a signal to the injector wire and the injector its self. only the ear test.

 

So how do you check the cable / injector with it in the car. im assuming the wire is just a case of checking with a meter, but what about the injector its self?

You can ohm test them, I can't post links from my phone. Try looking in the search or faq sections, under misfire? If I remember right set your meter in ohm mode, measure the two pins of the suspect injector. I think you want about 12 ohms.

I think you want about 12 ohms.

 

10 - 14 ohms!

Yes use a multimeter set to ohms, a reading between 10 and 14ohm is within range and anything outside that then its shot. I did mine this week and had one injector at 17ohms, replaced with a spare at 12.5ohms. The injector was still working by the way with the screwdriver test, but would have been and was overfuelling.

Correct. You can also hook up a 9v battery and watch down the plug hole to see if it sprays.

Coil packs as you look at the 3 pins from the side of the engine, middle and left pin and need to be 0.7-1.0 ohm, mine were all 1.0 ohm
