Fuel Injector Tester and Fuel Injector Cleaner Tool Kit, 4 Sizes Adapter 8 Pulse Modes DIY Cleaning Tools Kit 12V Fuel System Diagnostic Injector Tester

My car would not start after having sat unused for a long time. I could measure fuel pressure at the intake and I had spark at the plugs, so I had to wonder if the fuel injectors were firing. I got this tool and found that 6 of 8 injectors were not firing. This tool is not expensive, but saved me a lot of time and aggravation by quickly diagnosing the problem.

Cleaned my injectors out quickly and easily. Can’t beat this with how inexpensive it is.

Works great! Just don't try to clean low impedance injectors, this unit will stop working forever. Other than that, if the DC power cord was longer, it would be great, as it is way too short to really give you some distance from the 12v battery in your car(if you're planning on using this tool like that).

Worked like a charm! Used it to test and clean some solenoids in my transmission.

Performs the function as stated but the case is low quality plastic that is melted by the carburetor cleaner required to clean the injectors.

My son and I found this tester easy to use. We were working on a 2008 Chevrolet Cobalt w/2.2L engine. With this test we found 3 out of the 4 injectors were bad. I am planning on buying another one in the near future. Thank You

Worked. I had a slight problem with the spray adaptor on the spray can. it was a little messy. Injectors were cleaned very fast. (I used seafoam). Solved my 2.4l Ecotec misfire and camshaft/crankshaft timing issue. i would recommend this product. 4 stars because of spray adaptor mess.

I was only able to test 2 out of 8 2000cc injectors. The module has power and the buttons worked. When I press the Pulse button, the dot appeared next to number setting to send a signal. But, the other 6 injectors didn't click on. And the first two didn't work either.
