Designed for gasoline engines with electronic fuel injection, the EM276SET works alongside any fuel pressure tester and is powered directly from the vehicle’s 12V battery. The unit features an easy-to-read LED screen, eight pulse settings and four pulse output types to match common injector behaviours.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the EM276SET help diagnose injector problems?\u003c\/h3\u003e\n\u003cp\u003eThe tester fires individual injectors on demand so you can observe each injector’s spray pattern, listen for consistent clicks and monitor fuel pressure changes while the engine is off. By isolating injectors, you can pinpoint failures such as electrical faults, clogged nozzles or internal leakage without swapping parts indiscriminately.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eEight pulse modes to simulate different injector operating conditions\u003c\/li\u003e\n  \u003cli\u003eFour pulse output types: short, medium, long and continuous\u003c\/li\u003e\n  \u003cli\u003eWorks with any fuel pressure gauge for correlated readings\u003c\/li\u003e\n  \u003cli\u003eIndividual injector operation for targeted diagnostics\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I use this kit to clean sticky or gummed-up injectors?\u003c\/h3\u003e\n\u003cp\u003eThe EM276SET is designed to assist DIY cleaning by repeatedly pulsing injectors while cleaning solvent circulates, helping dislodge varnish and deposits from the nozzle.
