Looks like I have the infamous adapter for the rotor. The push on distributor can't work with bolt on because the center pin is too far away and it has to shoot a bolt of lightning to reach causing it to burn up. It is also possible to test the IAC on a noid light without removing it from the light. To do this, you will need to locate the two wires coming out of the IAC. What Does a Noid Light Test: A Noid light is a diagnostic tool used to test electronic fuel injection systems. It is used to diagnose problems in the electronic engine control system. The Noid light consists of an LED light which is connected to a power source and a connector which plugs into an EFI system. When the light is illuminated, it indicates that the system is working properly. If the light does not come on, it indicates a problem in the system. What Materials are Needed to Make a Homemade Noid Light? If the noid light stays on, with the key on or when cranking. Then, chances are wiring on the ground side of the circuit, is either shorted out (shorted to ground). Similarly, the driver inside the computer is bad and the computer may need to be replaced. However, if the light does not indicate any blinking or does not light up, it is likely that the electrical circuit that delivers fuel to the injector is faulty. It is important to repeat the same process for each fuel injector to ensure that each one is receiving the correct electrical signals. How Do I Make an Injector Pulse Test

Summary: A noid light is a diagnostic tool used to test the electrical pulse signal sent to a fuel injector from an Electronic Control Module (ECM) in a vehicle. Making a noid light involves gathering the necessary materials and following a few steps to assemble the device. You will need an LED bulb, a resistor (approximately 220-ohm), a connector that matches your vehicle’s fuel injector harness, some electrical wire, heat shrink tubing, and a soldering iron. So my thinking is that fuel injector #4 is failing. Is there a way to test it before I replace it? And if I have to "drain the fuel" already in the fuel injector manifold thing how do I do that so it's not leaking fuel all over and not so messy? This is one of the most complete Noid light kits on the market. It contains Noid lights for the different fuel injector connectors used on the majority of makes and models, since not all cars use the same fuel injector connector type. The fuel injector Noid light test is done in conjunction with several other tests to find the root cause of the misfire or no-start your vehicle is experiencing. Best way to test an AFM is to probe voltage on the pin that sends variable voltage to DME. Resistance is a poor test on these AFM's and doesn't really help much but that voltage should be smooth.If everything is connected correctly, your Noid light should be working! Try it out by turning on the power switch and shaking the light up and down. You should see the LED light flashing inside the Noid light. Be sure to shake it up and down a few times to get the full effect. Step 4: Open up The Noid Light: Never force your noid light into the harness or into the fuel injector clip. This should easily slide into position and create a firm connection for you to test. Never use a noid light that’s intended for a different vehicle, and always exercise safety around your engine bay.

The first step in making a homemade Noid light is to connect the 12-volt light bulb to the 12-volt test light. This is done by connecting the positive wire of the test light to the positive wire of the light bulb and the negative wire of the test light to the negative wire of the light bulb. Once this is done, the 12-volt power source should be connected to the test light and light bulb. Testing the ConnectionThere are a few reasons you might want to make your noid light. First, it can be cheaper than buying one from a store. Second, you can customize your noid light to fit your specific needs. Finally, it’s a great way to learn more about how circuits work! Required Materials When creating the circuit, use positive (+) and negative (-) terminals on the battery and LED light. Also, make sure that the switch is in the “off” position before connecting the battery. Step 3: Complete the Circuit:

Attach the male and female electrical connector to the ends of the wire. Make sure they fit securely. I have power to the main relay when ignition key is on. I have spark. I have good fuel flow getting to the fuel rail, I have power to the injectors when key is on. If the Noid light DID NOT flash ON and OFF, this result indicates the fuel injector is either NOT getting power (usually in the form of 10 to 12 Volts) or that the fuel injection computer is NOT providing a fuel injector pulse signal to activate it. With this result, you have confirmed that the electrical part of the fuel injector circuit is at fault. In Conclusion This test should tell you whether or not your fuel injector harness is the problem behind your misfire. If your car does not start properly or starts slowly, this test can also help you identify whether or not the injectors should be firing properly.A fuel injector Noid light will help you to troubleshoot a misfire or a no-start condition or a bad fuel injector and is one of those MUST HAVE tools to diagnose the majority of fuel injected vehicles on the road today. There are many advantages to using an EFI system over a carburetor. The main benefits include increased fuel economy, increased power, and easier starting. How Do You Test a Fuel Injector with A Screwdriver? If you have a fuel injector not functioning correctly, you can test it with a screwdriver. First, remove the injector from the engine. Second, use the screwdriver to probe the four pins on the injector. The coil I bought was for the 14v upgrade I believe. It’s a silver Bosch coil with an orange top. It’s ohms right out of the box was 6300. 300 more than the spec in the Bentley recommends. Its resistance between the pos and neg polls is also out of spec. Not sure if that will wear other things out down the road.

For this project, you will need a few basic supplies. You will need an LED light, some wire, a battery, and tape. Step 2: Create the Lighting Circuit:The spark plug cables are different between push on and bolt on rotors. The ends where they go into the dist cap is different and I believe at the coil also, so they're not physically interchangeable. I'm sure things could be adapted and I'm not sure there's any difference electrically, but it would be a headache if you got the wrong one. I also spilled antifreeze on my speed and reference sensors when doing the heater core. Could that cause something to go bad? The first step is to set up your injector pulse test equipment. This includes an oscilloscope, an injector, and a ground clip. The ground clip should be attached to the car’s chassis, and the injector should be plugged into the oscilloscope. Start by connecting the LED light to the wires. Then, attach the wires to the battery clip. Secure the connections with electrical tape. Next, connect the battery clip to the 9V battery. Finally, attach the connector to the other end of the wires and plug it into the EFI system. How Do You Solder the Connections?
