testing needle lift valve in injector

[Madmark]

Can some one explain how to test ohms on the injector sensor to see if mine has failed. But treat me like numpty as I know very basic electrics but not when it comes to testing ohmage I have a good circuit tester to hand so what setting and what wire do I test from injector and engine running or not. Give me an engine ill rebuild it but electrics are witch craft to me

i think its not running,disconnect feed to injector and meter set to ohms + on wire and - to earth,cant remember ohms 100, reading but i am sure some one on her will put you ,me right.

Engine needs to be off your meter wont be impressed if you are testing ohm's through a circuit that is carrying a voltage.

So plug unplugged engine of and test ohms on plug terminals

or your meter is, always check the meter works properly before using, often with multimeters there is a buzzer option for continuity, select that and touch the probes, you get a buzz your good if you don't you may have faulty leads/meter
im sure its fine but we have to check our tools before we use them dont want a misreading at 240v so good practice

I tested it on my temp sensors and worked spot on so def injector is dead just need to find one
