Be careful not to spill any of your carb cleaner or whatever u use to clean the injector or else the exterior can get eaten by the cleaning solution

Looks like the tester is faulty, not providing sufficient voltage. Loss of time with this device.Connected directly to the car battery, the injectors open normally.

Connections could be a bit longer.

This tool was great to help me diagnose fueling issues with an older Volvo that had not been running in a couple of years. The instructions were easy to follow and the tool was intuitive to use. Definitely an essential tool for diagnosing fuel issues!

This was very intuitive and easy to work with. The adapter is great for cleaning the injectors. The different modes of the tester made it so easy to test and to clean my fuel injectors. The display is easy to read and understand. The buttons even make a click noise, so you know you have pressed them. This is a great tool to have in your garage if you do any basic maintenance to your vehicles.

this looks and feels well made. simple to use per the instructions. wiring and connection points feel like they're last for a good while, so this looks like a good choice in my books for having on hand for when an injector gives you trouble.

Nice tester overall. Nothing too high quality, borderline feels cheap. But does work really well. I’m not a mechanic by trade but do work on and fix my own truck. It’s nice to have this tester handy. Good price
