Alltooetools Noid Light Test Kit Fuel Injector Pulse Tester Tool

SPECIFICATIONS: This Noid Light and IAC Test kit includes eight noid lights, two 4-pin connectors, and a molded plastic storage case that allows you to take the kit wherever you need to go with ease. TESTING YOUR EFI SYSTEM: This Noid Light/IAC Test Kit allows you to easily eliminate a vehicle's electrical system as a possible cause when it won't start. Just disconnect the electrical harness from the injector, plug in the correct noid lite with or without an extension, and crank the engine for a few seconds. A flashing light indicates a correctly functioning electrical system, while a solid light indicates a malfunction. TESTING YOUR IAC SYSTEM: Our Noid Light/IAC Test Kit allows you to easily eliminate a vehicle's idle air control as a possible cause when it won't start. To test the IAC system, disconnect its electrical harness from the IAC valve and plug in the IAC signal tester. After creating a load on the engine and letting it idle, two flashing lights indicate that it's functioning, while one or more lights failing to flash indicates a malfunction. GET YOUR VEHICLE RUNNING SMOOTHLY: Fuel tester noid lights work with American domestic and European/Japanese imported vehicles with fuel injector systems; Includes 8 noids with different terminal pin configurations to match a wide variety of plugs (flat vs. rounded posts, wide vs. close apart, thin vs. thick); 3 noids compatible with GM, 1 compatible with Ford, 2 labeled Bosch, 1 GEO, and 1 MULTITEC-2 EASY TO USE: Disconnect fuel injectors, insert noid light, and watch the end of the extension when you turn over the engine (a flashing light indicates normal pulsing voltage); If the light flashes when the engine is on, the "engine control module" or "program control module" (not car computer) is giving the injector the current to open and close and therefore the injectors are receiving the signal to open and close solenoids to inject fuel; If not, injector may be gummed up and need cleaning
