IGNITION TESTER KITThis ignition tester kit allows you to test that power is getting to the fuel injector by completing the circuit, the injectors are being pulsed, and verifying that the electrical system is not malfunctioning. | DIFFERENT TERMINAL CONFIGURATIONSThis set comes with different terminal configurations to match a wide variety of plugs, so chances are if it is under your hood, it is in this kit. | EASY TO USEDisconnect fuel injectors and insert a noid light. If the light flashes when engine is on, the engine/program control module is giving injector the current to open and close. If lights flash and no fuel reaches cylinder, injectors are gummed or fuel pump is inadequate. If no gas reaches the cylinder, clean or replace injectors. |
