How to test fuel injectors with V309 Fuel Injector Tester?


Structure
  1. Clean the injector’s exterior with liquid before use. Place injectors in the ultrasonic bath after removing dirt, ensuring the fluid doesn’t exceed the pulse line connection port.
  2. Turn on the ultrasonic system to allow the ultrasonic energy to dislodge any particle buildup inside the injectors. After cleaning, recycle the remaining cleaning fluid.
  3. Fix the injectors on the main machine and test them for resistance, shorts, and current draw. Add the test liquid to half of the glass tube.
  4. We are performing leak tests, spray pattern evaluations, and flow rate testing on the flow bench. The technicians have now returned the injectors to the flow bench to retest all functions.

Love this V309 tester! It’s super easy to use—4 cylinders let me check injectors quickly, and ultrasonic cleaning works like a charm. 9 test functions cover every scenario I need, and the smart panel lets me tweak settings with one button. 12V/70V/120V voltages fit all my needs, and I can do everything alone. Saves time and gets injectors back in shape fast—worth every penny!

    Machine was having issues but the aftersale service was very helpful and they sent a new motherboard at their cost. Now the machine is working normally again. Thanks for the service and support.

    I put it through all of its functions. We pulled 2 fuel rails from a yard for our stock car. The V309 cleaned, tested each one. The volume cylinders are clear and well lit. The fittings were tight and we had NO leaks. Definitely worth every penny.

How to connect the wires to a GDI of a BMW N43 egine? Which one is Red and which Black (12V/150V signal) Eiko asked on 23/12/2025

Simply plug it in crosswise. If connected incorrectly, it won't work but won't damage the fuel injector.
