Hello, My name isXXXXX will do my best to assist you. Fuel Injectors are an impedance device, you can't really tell how well its working or not without charting its impedance on an oscilloscope or other device, and that would just be the coil, you'd have to do other tests to check the valve/nozzle is operating correctly. By showing you how to do an easy resistance (Ohms) test of the fuel injector with a multimeter. However over a period of time harmful deposits can build up around the injector nozzle. The drive circuitry for this type of injector is simple and sometimes referred to as a saturated driver circuit. In most cases, you can trace problems with a bad fuel injector to a clogged nozzle, stuck valve or failed coil. Repeat steps 2 thru' 4 on the remaining fuel injectors. The previous generation of GM V8 engines were equipped with the infamous ‘Spider’ fuel injector assembly inside the intake manifold's plenum (and which was prone to fuel leakage failures).

Injector data collected is based on the fuel injector cleaning and flow testing service we provided. Fuel injectors should be tested cold unless otherwise specified, temperature variances will change the readings. Although we do show some pressure rating, most injectors are designed to operate 36.25 PSI / 2.5 BAR or 43.5 PSI / 3 BAR - Chrysler and Porsche some times use 55 PSI / 3.7 BAR Estimated Horsepower figures are calculated at 80% duty cycle and 95% duty cycle also based on … A fuel inlet area at the top of the injector incorporates a fuel filter, which is the last line of defense for any contaminants that have made it past the fuel tank’s or fuel line’s filters. NOTE: The Suzuki 1.3L Swift fuel injector factory manual resistance specification is approximately: 12 to 13 Ohms.
