Faulty fuel injectors can cause havoc with your car. Fixing or replacing them will help prevent serious engine damage and improve your car’s performance.
INDENTIFYING BAD FUEL INJECTORS
Injectors can get damaged from poor quality fuel, corrosive injector cleaners and clogged fuel filters.
When an injector gets clogged or dirty, the fuel going to your engine will be restricted. This can cause a lean fuel/air mixture which in some cases may damage your engine. Symptoms to watch for include:
Bad gas mileage
If your car is struggling to start, won’t idle or feels slower than usual, you may have faulty fuel injectors. If you smell gas and your stalling while idling or experiencing a rough idle, your fuel injectors may be stuck open. Has the ‘check engine’ light also illuminated? Then you should immediately get your injectors checked out.
If you suspect that your injectors are faulty, and still want to conduct a test, you can check the injector’s coil. You will need a digital multi-meter and the resistance valve for the coil inside of the injector.
There are several other ways to test fuel injectors including checking for the circuit control, but most others are software-based and require you to test on a professional equipment which is called diesel fuel injector common rail test bench. With this method of testing, you can visually inspect and diagnose your fuel injectors.
Diagnosing a bad fuel injector early is important because it can help prevent further damage to your engine. A faulty fuel injector can cause poor performance, decreased mileage, and an increase in emissions from your vehicle. It can even lead to engine failure if not addressed promptly since running lean can burn out a piston. Early diagnosis can also save you time and money by preventing the need for more extensive repairs in the future.
