Car Injection signal repair tool

Helped me diagnose ECU problem on 3rd gen 4Runner.

Works good helped me confirm my diag to move on to the next step

Used these to test my fuel injector plugs and found the bad ones easily. I would say the the value for the money was well worth it. They are very easy to use and with the assortment, they should fit almost any make & model. The brightness isn't the best, but as I said I found the bad ones.

worked well to verify

Great little set, and the fiber optic extension is really cool

Does the job but the prongs just keep coming out anytime you remove it

none of the lights plug into a 4.8l gm fuel injector plug. I had to use pins in the plug, and attach jumper wires to the light. All the pins on the lights were too large or too far apart. Save your money, buy a brand name good one.
