This injector tester is designed to operate injectors electronically, allowing for the diagnosis of fuel delivery issues such as blocked, sticky or leaking injectors. It features switchable 12V and 5V outputs, depending on the type of injector being tested or activated. The tester offers four selectable modes: short, medium, long, and continuous, and includes an easy-to-read LED indicator. In continuous mode, the tester can also be used for injector cleaning. Additionally, it comes with three pairs of extension leads to facilitate use in restricted engine bays.
