Inadequate electricity, due to failure of the incoming lead or the fuel injector, will result in improper firing of the injector. Injector pulse width is the length of time the injector is open. finding shorted components The HP 547 current probe with a pulser is useful to track down short circuits. This way with a fuel pressure gauge you can pulse each injector for the exact same amount of time and see how much pressure changed on the gauge to see if the injectors all are flowing about the same amount of fuel or if one's partially plugged so the pressure wouldnt drop as much as a good injector. Whether you are looking to tow or race, we have what you need to make your truck perform. Jim Grant's Tech Tips '97 Chevy Astro, No Injector Pulse. The instruments are reasonably accurate. I really dont know where to start. If you have the engine running, you can check the MAP at idle (or you can guess - pick about ~25 kPa for a stock cam, ~35 kPa for a performance. Since we don't need nearly as much water as a forced induction vehicle, the pump will pulse on and off because it has reached the 100psi limit. But instead of buying one why not build your own for a fraction of the cost and have it working in an hour? Oscilloscopes are extremely helpful when you're testing and troubleshooting digital circuits. Jens von Holten, owner, and Tim Jilg, general manager of Fuel Injector Clinic, knew these injectors would be a challenge and since I would be tuning the Evo myself, they saw this as an opportunity to assist them in the development of new flow bench testing strategies to further improve the matching process of high flow fuel injectors in the nonlinear injector pulse width (IPW) operating range. Metal injector line from an older VW diesel or Mercedes. This device is based on the Homemade Tesla Coil project and uses an improved version of the ignition coil driver circuit to generate high voltages. Fuel delivery is controlled by pulse width modulation. This test will tell you if the computer is pulsing the fuel injectors open when cranking the engine over. Smooth running at low RPM is seldom required of an aircraft engine. Thanks again for your help Tom. did you actually pull the return line from the tbi and crank it over to see if fuel came out? check that before pulling things apart and buying new stuff. Furthermore, some newer injector circuits use high impedance injectors that WILL NOT light a noid-light. BMW E46 models with the 6-cylinder engine utilize one fuel injector per cylinder. Fuel Injector Cleaning Fuel Injector Cleaning; Fuel Pump Testing can tell you exactly how your pump is performing. We wrote up a diagnostic guide to help you identify the issue, so be sure to check it out if you believe that your fuel delivery system is fully clogged or if it's possibly just a single fuel injector not working at full potential. if you get fuel coming from the return line when you crank it then you have a problem with the injector. (crawling under car is no fun so). Practical Guide to Free-Energy Devices - By Patrick J. Why 22,648? I screwed up. The FICM is often mis-diagnosed and needlessly replaced. Engine RPM (speed) and manifold absolute pressure (air density) are the primary inputs that determine injector pulse width. It is capable of testing all sorts of digital and microcomputer projects. AutoSpeed reader Fernando Hood has developed a programmable extra injector controller and here's an overview of it. Quickly test the fuel pump pressure on most injector systems with this fuel injection pump tester. by Nenad Stojadinovic. Lashen Electronics Online is the place for all your electronic needs.

Re: DIY fuel injector pulse tool The one that I built does 1 second, 5 second or a continuous pulse. Outputs a square wave compatible with most logic families due to using the circuits own power source as reference. Ok, I am rigging a 94' pro-v 200hp on my brother-in-laws aquasport. Now injector is not easy to get to maybe today Found that I do have a pulse on injectors 1 & 4 The Voltage Probe that I built works very well to trouble shoot to find out what has to this truck D. I use a DIY signal injector (square pulse) it maxed out at 22,648. But most of all, to perform accurate fuel flow tests using the pulser and your fuel gauge. Making sure that the fuel-air mixture in the cylinder is set on fire at exactly the right moment to push that piston back down! Of course, these days all of these systems have been computerized and are all controlled by the computer.
