How to test a fuel injector circuit with a noid light (a ScannerDanner Premium video)

This is a basic test that anyone can perform using a conventional test light. A noid light is nothing more than a light bulb designed to be plugged into a fuel injector harness connector. In this video we will discuss the following test results: - noid light flashes - noid light doesn't flash - noid light is lit all the time Engine Performance Diagnostics chapter 18 page 4 Tools used - injector noid light - incandescent test light - digital multimeter Playlist - (Chapters 17, 18 and 19) Fuel Injector Testing https://www.youtube.com/playlist?list=PLAFYVCyenqcoYm94zK0-EP0ICsGWj_ICs Related videos - How to test a fuel injector (open winding case study) Nissan https://youtu.be/mmRhcVkJdeQ - Stuck Open Fuel Injector (how to fix) https://youtu.be/jsl531-6q-A - A free ScannerDanner Premium video (Fuel Injector Testing Part 1) https://youtu.be/6vIcu3NVfcU - How to test a fuel injector circuit with basic tools (open control wire) https://youtu.be/kQUtAs-VrDY - How to test fuel pressure, injector pulse and spark with basic tools https://youtu.be/SUxagOAVS5M For more information on this topic, I have written a “field manual” called Engine Performance Diagnostics which is available at www.scannerdanner.com as an eBook or paper book.

NOID lights are a main stay in automotive diagnostics, and injector repair. A Noid light is connected across the injector circuit, by disconnecting the injector circuit, and connecting it in place of the injector. The issue with a noid light is that it barely loads the circuit. In other words, a noid light is a regular filament light, which draws very little current, and not stressing the circuit. In other words, you could still have a faulty injector driver transistor and the noid light would blink like nothing was wrong. This is the danger of being misled by the noid light. The Loaded Injector Noid Light is the next step in evolution for a noid light. It is a simple gadget. It also proves how little attention is paid by equipment makers to what's really needed out in the field. The Loaded Injector Noid Light is a simple filament bulb, which is needed for injector testing, and a 20 Ohm resistor in parallel with it. An L E D is not a good option to test injectors. It simply draws too little current for the measurement to be definitive. The Loaded Injector Noid Light will pinpoint issues with the injector driver transistor, the 12 volt power feed to the injector, the ground at the E C M or the ...

simple to use Noid Lite Test Kit for fuel injector testing
I bought this 9 PC Noid lights test kit. It works on Ford, GM, and Geo car models. My car is a Ford Crown Victoria. You can find Noid Light Test Kit on Amazon (affiliate link): http://amzn.to/2qV6F0S There are fuel injectors on your car and they need to be spraying fuel into the cylinders. Every now and then, one or more fuel injectors won't spray because they are not either getting power or pulse signal from the PCM (Powertrain Control Module). When this happens you'll get a misfire condition and rough idle. This video is to show you how I use a Noid light test kit to troubleshoot fuel injector problems. A flashing light indicates normal pulses. No light or constant light indicates a problem. - If the Noid light flashes on and off then this indicates the fuel injector is getting power and that the fuel injection computer is providing a fuel injector pulse signal to activate it. Also, this test result eliminates the electrical end of the fuel injector circuit as the cause of the problem or misfire. - If the Noid light did not flash on and off, this result indicates the the fuel injector is either not getting power or that the fuel injection computer is not providing a fuel injector pulse signal to activate it. More specifics about this Noid light test kit: Quickly and easily tests electronic fuel injection systems on GM TBI, BOSCH PFI, FORD TBI GM PFI, GEO TBI, and GM SCPI, GM MULTEC 2, GM-1987, GM-1982 equipped vehicles. Instructions for Noid lights: Disconnect electrical harness from injector. Plug Noid lites into harness. Turn engine on. - If Noid light flashes, electrical system is OK. - A steady light or no light indicates malfunctioning electrical system. If problem persists, check fuel system.





Stuck Open Fuel Injector (how to fix)
2001 Dodge Grand Caravan 3.3 with a #5 injector control wire shorted to ground. This is a common issue on the Caravan and Town and Country models. The wire harness right above the Exhaust crossover pipe will melt together and cause multiple problems. MAP sensor codes, injector codes, TPS and IAT codes etc. This problem can also damage the computer ground circuit as well as any other sensors on the 5v reference circuit. (Injector control voltage will spike into the sensor ground circuit of the computer). Symptoms: - P0205 trouble code (Injector 5 control circuit fires improperly) - hard staring (long crank time) - start/stall - excessive fuel consumption - poor gas mileage - white smoke from tailpipe - fuel odor - low power - misfire Fix: - repair melted computer harness connector near Exhaust manifold crossover pipe (common problem) Testing methods shown: - how to test a fuel injector - how to test for a short to ground on a fuel injector - how to test for injector control Related videos: - How to test a fuel injector circuit with basic tools https://youtu.be/kQUtAs-VrDY - Fuel injector failing when hot (fixed with snow) https://youtu.be/b8ww7lMMpZ8 - How to test a fuel injector (open winding case study) https://youtu.be/mmRhcVkJdeQ - Stuck Closed Fuel Injector (how to fix) https://youtu.be/NXrd1fYwj1o For more information on this topic, I have written a “field manual” called Engine Performance Diagnostics which is available at www.scannerdanner.com as an eBook or paper book.
