I'm not sure what you're on about here mate

There probably won't be any values showing, beucause the injector will have to be unplugged for the test.

hi that is correct u need to unplug the injector and take the readings from the injector socket on top of the injector not the plug i am trying to work out weather the solonid valves on the injectors are faulty or not .

Any pics as to where they are? Can you not compare them to your others or are all 6 suspect?

hi big sig i suspect i have 2 injectors that are faulty if u look at the rocker covers there are three injectors sticking out of the top of the covers one at each end and one in the centre and each one has a electrical plug connected to it . if u unplug the plug from the injector with the ignition off u will see 4 electrical pins inside the injector socket i need to now what reading u get if u test the continuity between the top 2 pins and weather the reading is constant or disapears straight away .so i can comfirm weather i need 4 injectors or just 2 the way the car pulls when driving i suspect i need only 2 i brought some off flee bay but they were no good and made the car worse many thanks

Where did you buy the injectors mate? I bought 6 from vauxcentre on ebay. I hope I didn't get the faulty ones you got first

hi i got them from the same place and i took three back as they were faulty if u brought 6 then its possible they came out of a different car the ones i had came out of two different cars so i have a mixture of my origonal injectors and the rest came from them . and two of the injectors give different readings from the solonids on the injectors so i need to confirm which ones are faulty 2 or 4 of them but i suspect its the 2 that are faulty what does your car do and if u changed the injectors has it made it better
