It combines an LED pulse controller with multiple timing modes, silicone-insulated leads and two universal injector adapters in a portable bag so you can power the unit from any 12V vehicle battery and use it alongside a fuel pressure gauge.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the EM276SET help identify injector problems?\u003c\/h3\u003e\n\u003cp\u003eThe tester fires each injector one at a time so you can observe fuel spray, listen for consistent clicks, or watch fuel pressure changes to spot failures. Using different pulse lengths and patterns mimics engine signals and helps reveal sticking, leaking or burnt injectors without removing the fuel rail in many cases.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIndividual injector pulsing for targeted diagnosis\u003c\/li\u003e\n  \u003cli\u003e8 pulse modes plus 4 output signal types (short\/medium\/long\/continuous)\u003c\/li\u003e\n  \u003cli\u003eWorks with any fuel pressure tester to show pressure response\u003c\/li\u003e\n  \u003cli\u003eHelps detect stuck, leaking or non-firing injectors\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat safety and setup steps should I follow before using it?\u003c\/h3\u003e\n\u003cp\u003eFollow the printed warning on the unit, disconnect battery terminals correctly and work in a well-ventilated area free of sparks or flames.
