Fuel Injector Tester Cleaner 8 Pulse Modes Injector Cleaner Kit 2 Fuel Injectors Simultaneously Tester DIY Cleaning Tools with 40inch Power Cord,4 Injector Cleaner Adapter,Short Circuit Protection 12V

Why did you pick this product vs others?:Saw a review done on it, and the price point was right. Ease of installation:Very easy and straight forward to use. It gets cumbersome when you try to juggle the solvent cleaner can (carb or brake cleaner) and the device the injector uses to plug into it.

This thing works great! I used it to test some old injectors and compare them to the new ones that I'm about to put in the Jeep and I could visibly see the difference in the spray patterns between the old and new injectors. Just a side note, go to any parts store and get a can of brake parts cleaner or carb cleaner and pull the nozzle off. If it has a little white nipple sticking up, you can use it to pressurize the adapter and the injector will spray the cleaner so you can see what it's doing. Just hold the blue adapter in the palm of your hand and use the first two fingers to hold the injector in the adapter because the pressure from the can of cleaner will make the injector fly out. Also, please remember to point the injector in a safe direction and away from your face when you press the button to activate the injector. I found the 1,2 and 5,6 settings to be most effective for basic testing. They will be listed in the instruction manual, but they're basically low and high power single and rapid pulse settings, respectively. Use with caution and I think you'll be very satisfied with it.

Got the job done!

Works perfect good pricing..fast delivery.

I was working on a 20+ year old truck with no real maintenance record whose Check Engine light had kicked in, so I've been replacing parts that are inexpensive (O2 sensors and spark plugs) and testing those that cost some money (fuel injectors). I had bought a fuel injector tester kit that plugs directly into a 12V source but decided against using it. When a fuel injector is in an engine, the voltage (and therefore the current through it) is applied for extremely short durations. I was concerned that while testing I could burn up the coils and destroy the fuel injectors themselves, so I bought this one instead.Works great, only problem was universal for this style of tester: the amount of pressure coming from the carb cleaner can easily popped the fuel injectors out of the plastic attachment. The injector needs to be held tightly in place while simultaneously spraying the can, then this tool's activate button needs to be pushed.

Some injectors, like the ones from my Honda Accord, will not operate at the higher pressure from the aerosol can. I had 8 injectors to test, and 4 of them were out of a running engine. Couldn't figure out why they only worked a split second when I activated the aerosol can. They don't mention this, or at least not that I could find. I had no idea the pressure from an aerosol can could be too high for the injector to operate.

This unit is just what I needed! Thanks for the fast shipping.

Works to cycle injectors, but after cleaning 16 injectors over two separate days, it has already come apart. The injector cleaner spray it is supposedly designed for destroyed the pulse button already. I don’t know about you, but it is impossible to use this without getting any of the spray on it. Mine got a small amount of overspray but I think the button saw the most because the spray gets on your hands…the same hands you use to operate the device. Technically, it still functions but I doubt it will work for much longer.Edit: The seller has given me a refund without a request. Bumping to three stars for customer service!
