Finding the indications of malfunctioning fuel injectors is crucial before getting into testing. Typical indicators are poor engine performance, rough idling, lower fuel economy, higher exhaust emissions, and engine starting trouble. Also suggestive of injector problems are unusual sounds like knocking or ticking. Understanding these signs guides the diagnostic process and helps to focus on the problem. Refurbished fuel injectors often show these symptoms earlier. One typical problem with fuel injectors is insufficient fuel pressure. Measuring the fuel system?s pressure requires a fuel pressure gauge. Following your vehicle?s service manual for the proper location, connect the gauge to the test port on the fuel rail.
