If the noid light flashes on and off, then the fuel injector is getting both power and an activation signal. Locate the fuel injector that you're gonna' test and disconnect it from its electrical connector. If you don't know which one to test first, i suggest you test them all.

It actually spins over very strong, but not even a hint of fire going on. Also, this test result eliminates the electrical end of the fuel injector circuit as the cause of the problem.

My relay for the injectors has an output indicator light which illuminates when the ecu sees rpm, as does the fuel pump comes on while cranking. Once you have unplugged the fuel injector connector from the fuel injector. If the noid light flashed on and off and this flashing was comparable to the fuel injector connector next to it, then this result indicates the the fuel injector is getting power (usually in the form of 10 to 12 volts) and that the fuel injection computer is providing a fuel injector pulse signal to activate it.

It’s true that you can use an automotive meter for the same test. 4.7 out of 5 stars. The noid light wont test the injector it will just tell you that the injector is getting a pulse to test the injector it self you realy need a injector test set up, unless its a throttle body then you can use a timing light to see the spray pattern, is the engine missing or you just want to test wireing ?as far as the led sounds right to me jc

A noid light is simply a little 12 volt light bulb that has two terminals that fit into the fuel injector's connector. This is only one possilble cause why your car’s engine won’t start. This result indicates that the fuel injector is receiving power and the on/off signal from the fuel injection computer.

If the engine is started, the noid light should flash on and off all the time the engine was running. So, all fuel injectors need power and a switching signal, from the fuel injection computer. Unplug an injector and plug the noid light into the harness.
